Network cable is un-plugged! No it isn't.

[cozzy]

Hello. I bought a new computer 7 days ago so we could have internet on 2 computers so to lessen the queue time waiting to go on. I've connected the network cable & router & modem properly & used the router set-up disk on the new computer only. I cannot go any further than this coz both computers tell me that "A network cable is un-plugged". It is definitely plugged into both. I bought another cable but they still tell me its un-plugged. Internet still works fine on the old computer (1 year old), but when its hooked up to the new computer the connection is lost every minute.

I cannot set up the internet or network connection on the new computer at all coz, you've guessed it........."a network cable is un-plugged"

Using 2X AMD Athlon (Maxdata) computers, both using Windows XP & service pack 2. USB ADSL BT Broadband modem X1, 2X micro filters & 1X router.
The new computer is just left idle, please help.
Cheers! :cry:

try reinstalling the NICs?

[Cain]

I agree w/ steosaur(oWn) ..sounds like a bad NIC maybe? xp should auto recognize
hardware while hot.. (although not reccomended..) try reseating the card whilst the
system is on ;) dont fry yourself. thats a 400w+ power supply.. toast it can make

[cozzy]

What card? Do you mean a network card? Don't even know if the puter's have got network cards in them, although they are pretty new.
Never opened a puter B4 & would not know where to look anyway.
Is there a way to find out if the puters have got network cards through system information? Both puters have a red cross on the bottom right of screen saying that a network cable is unplugged. So does that mean they both have cards? Or, one or both of them ain't got one & that's why they are saying a cable is unplugged!
I got an explanation with a sketch of how to connect a 2nd puter in the home, to the same internet connection, but there are too many abbreviations in the thing & i don't understand it. Maybe i've got my wires mixed up.

Any chance of telling a new born kid how to do it?

Cheers boys.

If God lived on Earth he would get his windows put through.

No time like the present to learn by doing. Join the club. I dont think I know a
quality tech that didnt learn by crash n burn. Its your turn now.

Each machine that accepts an 8wire RJ-45 type cable 'straight' not 'twisted'
(this is a type of wiring scheme that differs at the jack at each end of a cable
or is the same; im not talking about shape. sometimes just any ol; RJ-45 cable
wont do.) What that cable plugs into is an ethernet connection, 8 wire.
This is used predominantly for DSL/CABLE internetworking sououtions with or
without 'hubs' in between. If you use dial up you use a 4 wire phone line type
RJ-15 (I think) that would connect a modem in your pc directly to a phone line.

Regardless, both are located (sometimes on the motherboard as a component)
in slots that are filled with 'cards' NIC, Graphics, sound.. all can be 'on board'
but most often the best are on add in cards.

If you dont know what you've bought you can start with the motherboard
manual and reciept. This will also give you an idea of whats inside. (crappy
little black and white pictures.)

If you still cant get it to work call your ISP. Maybe they do somthing special
and can talk you through an average setup or advise the purchase of new
hardware. If they go nuts and just cant help you over the phone ask them to
send out a tech. dont forget to pay them, theyve earned it.

to find out what NIC you have click on control panel----system----hardware----device manager---then look at what net adapter/s you have
Look at the cable connecting your comp to the internet and tell us how many wires you can see at either tip/end of the cable. And then tell us that it fits/or doesn't fit the hole in the back of the comp.

but an RJ-15 (phone line) will fit into an RJ-45 (ether) port.. ..and it wont
work but the converse isnt true..

Both puters have got 1394 Net Adapter & VIA Rhine II Fast Ethernet Adapter. The downstairs puter has BT Voyager 100 ADSL Modem. I'm wanting to get the upstairs puter connected to the internet using the downstairs internet connection. The downstairs puter is one year old, the upstairs puter is brand new & i still do not know if there are network cards in either of them!

I can see NO WIRES at either ends of the network cable as it is plugged at both ends.
It is connected properly to both puters but yet, both puters say its unplugged. The internet works just fine on the downstairs puter, but, when i connect the cable to the upstairs puter & switch the upstairs puter on, THEN the internet will not work at all on the upstairs puter coz it says "a network cable is unplugged". Yet, something IS happening because the downstairs puter then loses the internet connection about EVERY MINUTE, time & time again, until i switch the upstairs puter off. So something is happening somewhere.
The downstairs puter then works 100% brill & never loses the internet connection so long as the upstairs puter is switched off. Phew! Upstairs Downstairs = Soap Opera.

[Sphyenx]

well the computer's should get connection feed if you have your modem correctly set up (checked) then you have the router configed for both PC's etc with all drivers and you pluged the cat5's or usb etc in to the two PC's while they were off and booted up correct? I some times get that error but im wireless so I can't compare. I got an idea first take out all the cord's. Reinstall the router so PC 1 work's. Then if you get internet. Set it up so that PC2 will get conection, then run down and plug that one in and boot it up. WALAH you should be up and running. It worked for me. I got a few 50foot CAT5E's

[cozzy]

Nope i cannot do it. The downstairs puter now says "BT internet shared" (at least something different has happened). We got a new puter we don't use coz i can't set it up to share the internet with the other. I can ring a chap who charges £30 an hour to sort it, but, trouble is, i don't want him coming just to say that we need network cards! I still do not know how to find out if there are network cards in the puters. One is new & the other is a year old. Should there be network cards in from new?
I still get the message from both puters that a network cable is unplugged. but it's plugged into both of em! Am i sticking the wrong wire into the wrong hole?

[Thong_Ispector]

It looks like we have some good people here trying to help you.
What it looks like we need is to get the terminology down so we all understand what is being said.

If you bought network cables and there is a place to plug them into the back of your computer you do have network cards or built in network interfaces...

I saw your post 1394 and VIA... Ok, 1394 is your firewire adapter, good but not what you will be using for your network connection...

The VIA is what you will be using...

Can we assume that the downstairs computer was connected to the internet and working fine when you started this project?

Was the downstairs computer connected directly to the modem with a network cable before you added the router?

Did the downstairs computer connect to the internet through the router before you added the connection to the upstairs computer?

What make model and type of modem are you using?

What make and model of router did you purchase?

Did you use the network cable that was on the working system to connect the working pc to the router or to connect the router to the modem...?

If the existing cable was a crossover cable and you used it to connect to the router instead of using it to connect the router to the modem that might be the problem. Also some systems require the use of a crossover cable when adding a router to an internet connection... or connection to a crossover port on the router...

Which ports on the router do you have plugged into which cables/devices?
Does one of them indicate crossover or have a switch beside it?

Answer these questions then we can move on...

[Sphyenx]

50 ft cat5e's lol I lovem best 20 buvcks ive ever spent. I bet you could get them cheaper. Staples, Newegg, tigerdirect, wallyworld lol. You know!

[Thong_Ispector]

I just make my own...

I've strung miles of cat 5...

We never started a run with a used box... Always a new one...

The back of the shop was always piled high with partial boxes free for the taking...

Often they had a hundred feet or more...

I even ran quad shielded dual runs to every room for Tivo and DTV hookup and RG cross-connects ...

I have WAY too much time on my hands...

[aeinstein]

i've been away from these boards for awhile, so i'm sorry i didn't jump into this thread sooner, but it looks like it might still be active. I hate to tell ya but the 1st thing i wud of done after realizing the new setup wasn't working would have been to re-confirm that the original setup was working (which i think u did), and then, considering the error msg u were getting, i would have swapped the "old" pc's rj-45/ethernet cable with the new rj-45/ethernet cable from the new pc - if the old pc failed to connect at that pt u knew right then & there that cable was hosed - even tho it's new & even if the nic's link/speed led(s) lit up properly. if the old pc connected then u would've know it was an issue w/pc, but still needed to determine if it were a soft/ware or a h/w issue, or simply a configuration issue. if this is still an ongoing issue then i'll be happy to walk you step-by-step through t/s ur connection.

[cozzy]

Yep, some good folk helping...Aeinstein & Thong Ispector cheers & happy new year to ya.
Although i'm pretty good at working AT a computer i'm lost when it comes to doing anything externally with them as you can see. I'll try & answer your questions. 1st of all, there is definitely network cards in both machines, i know this because i watched the progress of scans & the program said at some stage, "scanning network card" in both puters.

I bought network cables, router, & all other gizmo's required to connect both puters to the internet, from the same shop, with the new puter. I told the chap exactly why i was buying a new puter.....so we could have them both connected to the internet. So i've got everything needed to do it. Driver discs etc, & everything is new. I bought another network cable & connected both puters but it still says on both of em that the network cable is unplugged.

I don't know what the 1394 & VIA are? There is only one possible place to plug in the cable & it is connected correctly. The cable is plugged in next to the printer's connection on both puters. There is nowhere else for it to go unless i can get an oblong end into a small round hole! (met the wife)? hehe.

Yes, the downstairs puter is fine & has always been ok with connecting to the internet. It has always indicated with an icon on the bottom right of the task bar that a network cable is unplugged. Which was fine because we just had a BT Voyager 100 USB ADSL Modem connected into the puter, & a setup disk to install the modem, drivers & BT help program. It was a breeze. But no, there was not a network cable involved here, but we need to use one now.
Now that i've added the router & gone through network setup wizard several times the downstairs puter works completely fine with the router & original modem connected, along with the network cable of course. Yet, it still tells me the cable is unplugged. Then, if i go upstairs & switch on the new puter, the downstairs (1 year old puter identical to the upstais one) keeps losing the connection. So, even though both puters say "a network cable is unplugged" i can tell them "it isn't" cos why does the downstairs puter now decide to lose internet connection every 30 seconds? Turn the upstairs puter off & everything is fine with the other. The downstairs puter states that "internet connection is shared". The upstairs puter just will not conect to the internet at all, it tells me that an internet connection does not exist.
i've installed the drivers that came with the router, on both puters, & have installed BT broadband onto the new one. Is this correct? I've been through both wizards a few times but no joy.

The router is ADSL high speed internet access bridge, & the make is MENTOR, & it has 4 ports!

I cannot really answer the question whether 'i used the netwok cable that was on the downstairs puter to connect the working pc to the router or to connect the router to the modem". There wasn't an existing network cable? Don't think so anyway? Just like i said above...modem plugged into the back & away it went ok.

I don't know what a crossover cable is? He just gave me a 15 metre network cable to connect both puters & some other smaller ones for the router & modem. Thing is, we have 2 short cables which are "left over", there is nowhere, absolutely nowhere they can go?
I don't know which ports the router is plugged into which cables/devices? There is no switch anywhere. If it indicates a crossover then i don't know what to look for?

Thanks again. Hopng my next post will be a 2 liner.
P.S. Need any help with Databases? I'm your man.

[aeinstein]

ok, i'm going to tackle this 1 thing @ a time.

1), pls confirm that currently ur isp (internet service provider) cable connects to your BT Voyager 100 USB ADSL Modem which connects to ur router (confirm specifically that this is a router & not a hub; pls post make & model info), which then is connected to each of ur computers, &

1a) confirm that all of the intervening cables (between the cable modem & router as well as between the router & computers) r ethernet cables

in the interest of time i'll assume that the above is the case & move on

2) what is the ip address (internet protocol address) that the router gets from your isp? (call ur isp if necessary to find out, but u should be able to get it by checking ur router's config info; the ip address will be delineated by 3 periods (###.###.###.###), such as 170.20.0.5 (fyi: most programs will drop leading zeros where applicable, so that an ip address that is actually quadradically notated as 170.020.000.005 is displayed as 170.20.0.5) btw, u dont need to tell us the last quad (the ".5" in my preceeding example), just mark it as x's (170.20.0.xxx).

3) what is the ip address assigned to each computer (all the numbers)?
3a) what is the subnet mask assigned to each computer (all the numbers)?
3b) what is the work group name assigned to each computer?

**********
you can get the ip address, subnet mask & work group name by completing the following steps on each computer:

1) click (left-click through-out, unless otherwise specified) the Start button
2) on the lower-right of the pop-up menu click Run...
3) in the Open: box type cmd & then click OK
4) this will launch another window open, typically with a black background & white text (it doesn't matter if the colors on ur system r different) & in the window title bar just to the right of a little icon that shows C:/ u'll see something like C:/WINDOWS/system32/cmd.exe (if u typed command instead of cmd u'll c command.com at the end rather than cmd.exe; either way it's actually the same program)
5) in this new window type ipconfig/all (ipconfig /all works as well, but ipconfig / all wont work), & then hit ur enter key; this will display the pc's ip configuration info
6) right-click the little C:/ icon up on top (next to where it says C:/WINDOWS/system32/cmd.exe), which activate a drop-down menu
6a) with the cursor, momentarily hover over Edit on the menu (this will activate another drop-down menu), & then click Select All (this may temporarily reverse the colors within the window; i.e., if the text had been white on a black background it will now appear as black text on a white background; the colors r immaterial)
7) once again right-click the little C:/ icon at the top of the window
7a) with the cursor, momentarily hover over the Edit on the menu & then click Copy (dont close the window yet - just incase u need to retrieve the info again)
8) if the computer is connected to the internet open a reply to this thread & then hit ctrl-v (by holding down the ctrl keyboard button, hitting the v keyboard button & then letting go of both buttons together), which will paste the information that u copied from ur computer in the preceeding step into the reply window for this thread; add which computer this info is from & submit the reply
8b) if the computer is not connected to the internet (or if you want to get the info from both computers & make a single reply post to this thread), after u've copied the computer's ip configuration info (steps 7 & 7a), click Start
8bi) click Run...
8bii) in the Open: box type notepad & click OK, which will open the NotePad text program
8biii) paste the info into notepad (by repeating the ctrl-v operation, as detailed in step 8); after notating which pc this info is from safe the file

if ur not able to copy this file from 1 pc to the other simply e-mail the info to urself & then access ur email from the other pc.
**********
**********
as mentioned in 3b above we also need to know the work group name for each computer. ther's a couple of ways of ferreting out this info, but a straight-forward method is as follows:

1) click (left-click unless otherwise stated) Start
2) click Control Panel (u may see a link that says My Network Places, if so click it & skip down to step 4 below - i think u probably will c that link, but since i'm not currently running a network i don't have it for reference on my pc)
3) double-click Network Connections
4) click the link off to the right that says My Network Places
5) click the link off to the right that says View workgroup computers

this will display an icon showing the name of the work group and then under it the computers currently accessible within the work group. if for some reason u don't c this icon (such as in my case since i don't have a network setup) u will still c the work group name as it will be displayed as the title of the window (at the top of the window, above where it says File Edit View etc).

pls dont forget to provide both the ip configuration information as well as the work group name in ur reply post!
**********

ok, once uv confirmed & provided this info we'll go from there! HTH :)

Sory i've taken so long, it's a long story. My wife did this bit of info on the upstairs computer & i've noticed it's different to the one that i did above as there is no ip address on this one! So i didn't have to inser them xxxx this time. She couldn't email the info to herself as you suggested, as we cannot, as you know, connect the upstairs computer to the internet.

Regarding the 'workgroup name', i'll say that there isn't one. I did give a workgroup name when trying several times a couple of months ago but have forgotten what it was! I've since deleted all drivers & traces of my attempts from the upstairs computer as i decided to start from scratch. I ended up with 4 'connect to web' on the programs list & got confused & deleted & uninstalled the lot of them.

Curtrently, the router & all cables & discs are now back in their boxes.

There is something i've come across since. There are 2 questions for you. Do i check the box in internet option properties, advanced, wher it says 'allow other web users to share files & printing'? & Do i check the box in the BT internet provider property box, where it says, 'Allow other users to connect through this computer's internet connection'? I did not know about these options before. Besides, i just thought the network wizard was all that was needed.

Also, i'm still unsure whether or not i should install the router, once at a time, separately, on both computers! Can't remember if i've already tried that.
Gosh i feel like a goon. Cheers.

I've since deleted all drivers & traces of my attempts from the upstairs computer as i decided to start from scratch.

depending on how you went about deleting the "drivers," if that's in fact what you deleted, it may have been inadvisable or it may be inconsequential; either way it's done now!

Do i check the box in internet option properties, advanced, wher it says 'allow other web users to share files & printing'? & Do i check the box in the BT internet provider property box, where it says, 'Allow other users to connect through this computer's internet connection'?

well i most certainly would not on a stand-alone pc (even if you're connecting through a router), but i don't use any type of resoure sharing programs, such as bearshare, grokster & kazza for music, which may need those settings to be selected. if you do use such a program then i would suggest that you post an inquiry on how to setup your computer in order to use the program(s) safely and securely as a separate post in an appropriate forum. if you're using the router to connect and share information between the two computers then you would need to have the files & printing box selected on both computers; you'll need to call you're isp about the BT setting (my inclination is to say no, that the BT box shouldn't care what's on the private side of the network - your computers - and the setting is to disallow/allow (unchecked/checked) public access to you're computer(s), but without being familiar with the unit that is purely a guess on my part; be safe & find out for sure from the source!).

Also, i'm still unsure whether or not i should install the router, once at a time, separately, on both computers!

eventually yes, but this is how i would do it:

for both computers do the following:
1) open Control Panel
2) in Control Panel open System
3) once System is open click on the tab that says Computer Name
4) copy down what it says for Computer description, Full computer name and Workgroup.

Technically the Computer description and the Full computer name can be the same for that one computer, but I would and do use different names for each. In any event they should be different from one computer to the next. On the other hand, the Workgroup name MUST be IDENTICAL from one computer to the next for each of the computers that you want to share information on and between. If this is not the case then do the following:

1) Decide what you're going to use for each Computer description and Full computer name, as well as what the Workgroup name is going to be.
2) Run the Network Setup Wizard on each computer that needs to have the above referenced information changed. I would tackle this by addressing two issues at a time: 1) making sure the information is correct, and 2) making sure each computer can connect to the internet. In that vein as a basic step I would run the wizard on each computer, even if you're going to input the same information as referenced above, but while it is connected directly to your isp - that is to say not through the router.

First you need to ensure that each computer can connect directly to the internet, bypassing the router. If not you need to contact you're isp to troubleshoot that connect (it can be SO many things that for me to walk you through t/s the issue would be very inefficient - not to mention time consuming! - so let's have the ppl who you're paying to help support connection earn their paycheck!). Once each computer can successfully connect to the internet, but before you connect them to the router, run the Network Setup Wizard to ensure that both computers are setup with the appropriate information, as discussed above.

To run the wizard complete the following steps:
1) open Control Panel
2) double click on the entry/icon for Network Setup Wizard
3) the welcome screen will open up, click Next
4) the review screen will open up, click Next
5) select the second option "This computer connects to the Internet through a residential gateway or through another computer on my network." (even though you're connecting to the internet directly with the one computer that you're running the wizard on, for now, use this setting), click Next
6) the Computer name and Computer description page will open up, change any information as appropriate, click Next
7) the Workgroup name page will open up, change this entry as appropriate (remember that the Workgroup name needs to be EXACTLY the same on both computers), click Next
8) the File and Printer sharing page will open up (since you want to be able to share files between the two computers you are going to need to enable file and printer sharing by selecting the first choice, but if you're using any internet based resource sharing programs/services you FIRST need to find out how to safely and securely use the program(s)/service(s) while protecting your computers from unauthorized intrusions), make appropriate selection, click Next
9) the information confirmation page will open up, scan info to confirm it's accuracy - hit the back button as appropriate to make any necessary correction, click Next
10) the network disc page will open up, since both pc's are running WinXP select the last choice "Just finish the wizard; I don't need to run the wizard on other computers." and click Next, and then click Finish on the last screen.

Once you have tested each computer's internet connection successfully and and confirmed that the appropriate computer name, full computer description and workgroup name has been entered you're ready to connect the router. I should mention here - actually, probably earlier in this spiel - that when you're switching the connection around you may need to reset the ip address each computer is using as well as the connection from the BT dsl modem. The most straight forward way to reset the computer is to do a normal shutdown (not a restart) on the computer, switch whatever equipment needs to be changed (i.e., changing the connection from one computer to another one, or changing it from the BT unit to the computer, to that of from the BT unit to the router to the computer, etc.), powering down the BT unit (check with your isp to ensure that powering down the unit - typically for 10-15 seconds - is the correct procedure to reset the BT, otherwise follow their instructions on resetting it instead), and then powering each unit up in sequence of connection (i.e., BT unit first, wait until it is up and running and showing a connection to your isp - check with isp help desk for appropriate indicators, power up router, wait two or three seconds and then power up the pc).

For instance, if I was using one pc directly to my cable modem and i wanted to change it so that i was connecting two of my pc's (which have been previously tested for connectivity and had their settings verified), i would complete a normal power down on both computers, ensure the router is powered down, and unplug the power cord to my cable modem. I would wait a few seconds for the modem to reset and forget whatever it had been connected to (although just a momentary disconnect should be sufficient to reset my cable modem it may be necessary for me to leave it powered down upwards to five minutes to clear up any memory cache issues, especially if the modem has been u/r continously for 30 days or more). While the modem is reseting I'll change the ethernet cables around so that I have the cable modem connect to the router and the router to each of the pc's. Once the modem has been powerd down for a sufficient length of time I will then power the modem up first, wait until the LED lights indicate it has successfully negotiated a connection with my isp, then I'll power up my router, wait momentarily and then start up each of my computers that I've connected to the router. From there I'll test the internet connection on each pc and if all is well I would be off and running.

Ok, I hope this helps! Once you've gotten each computer connected directly to your ISP and successfully connected to the internet go ahead and reconnect the router, resetting the connection as referenced above and/or as per your ISP help desk's instructions and let us know what happens!

My recent experience hooking an extra computer to my network may help.

I tried everything and my new internet connection ran too slow to do anything. I suspected the cable from the beginning but plugged it into one of the working computers to test and it ran fine. It was a long cable and so I moved my router to try a short cable in the new computer. I was up and running. Lesson is - don't trust the cable. I could not believe it would work in one computer and not the other. But I have no problems now.

if the cable worked at one location but not another - or didn't work that well at the other location - then the likelihood that it was the cable is remote; more likely when you had the cable snaked through the long run it was too close to a source of electro-magnetic/RF interferance, such as too close to a florescent light, especially the ballast mechanism, a step down transformer commonly used for thermostatic controls and/or door bells, etc. After all, a cable can't fix itself so when it's broken (or, as in your case, slow, due to electrical/mechanical defect), it stays that way.

I hear ya, aeinstein, however, and I thought that too but in the end, reality was stranger than theory...the detailed explanation follows, just because:

It was actually a cable I salvaged from my wife´s school when they tore it out. It had a regular connecter on one end and a wall socket on the other. I had a short ethernet cable plugged into that and into the nic. The whole thing was about 20´ long, basically because the short cable wouldn´t reach and I was too cheap to buy another one and don´t have crimpers. I suspected the cable with the wall mount but since I plugged it into one of the working computers and it worked, didn´t think about it anymore. After tearing my hair out and troubleshooting everything else possible, I finally just moved the router closer and used the same short cable (without the wall-mount cable) from the router to the computer. It worked perfectly. I plugged it back into the wall-mount cable and it ran slow. Plugged the wall-mount plus short cable back into the working computer and it works fine. The run is the same, in fact, I just now put the working computer (it´s a notebook) in the same place as the new addition and it works fine. Works with the notebood, doesn´t work with the new addition in the same exact place. The same short cable unplugged from the wall mount and plugged into the new addition works fine.

I don´t see how it´s possible but when you are faced with the impossible, I guess you´ve got to accept it.

I´ve seen some strange things in this networking world.

...It had a regular connecter on one end and a wall socket on the other...

Hmmm, something doesn't seem quite right about that scenario! What to you mean by "wall socket"? Is it a female connector? If it's a female connector how are you connecting the end points & to what (i.e., one end to a router & one end to the notebook/pc), especially the "wall socket" side?

There's nothing mystical or impossible about the workings of cable: it's either working properly or it's not working properly, and when it's not it be exhibited as anything from a rarely encountered intermittent issue to a full and consistent cessation of functionality.

In this case it sounds like it could be a faulty connector that when connected to the additional cable is seating in such a way that permits data transfer, or that there is a break in one, or more, of the cable's wires that comes into play depending on how the cable is laying when the other cable is being used versus when it's in use by itself.

I understand what you are saying and the reluctance you have in buying what I´m saying. Believe me, I tried everything in solving the problem I had before I finally replaced that cable. I just didn´t want to go out and buy a cable because I don´t have access to cable and the only place I could buy a 25´ cable charges $25 for them, if you can believe that...

But here´s the scenario (and forgive me for a long post - for such a stupid problem, it takes forever to explain it so you will know I´ve tried everything :!: ):

I had two of these cables, one end a standard connector, the other end a wall-socket(yes, a female connector, the contractor that installed them put a box connector on them so that standard cables could be plugged in and out as needed (there were only so many computers on rolling stands and they could be moved around the classroom)). I salvaged them and was using that, with a normal cable plugged in to provide the male connector to plug into the new computer I was putting on my network.

I tried both of them - I was not getting a connection, then getting a very slow connection, yeah, it was very flaky. But I have another cabled computer on this wireless net and when I tried the cables in that computer it worked fine. Normal speed, no problem. Plugged the cable in, got the connection, unplugged it and the connection went away.

But when I plugged them into the new computer, it was flaky. Follow my troubleshooting here. I changed nics, no difference. I changed hard drives (I had two different drives with two different O/Ss in the chassis, no difference, I changed drivers on the nics, no difference. I changed chassis, no difference. I kept coming back to the cable BUT, since it worked in that other computer, I just could not make myself believe that the cable was at fault.

Finally, after many wasted hours and much less hair, I just unplugged everything and put the router across the desk and across the room so that I could reach the computer with just the short cable that was plugged into the wall-socket end of the long cable (should have tried that in the beginning but, again, I couldn´t believe it was the cable when it worked in the other computer). Imagine my surprise when I immediately got a connection at normal speed. I put the salvaged cable back and got no connection, tried the second one and got no connection. Put the short cable back in and got the connection.

So, I just ran all my cables so that the router is closer to the new computer and it´s all worked with no problems ever since. Faulty connectors? maybe but I plugged them in an out so many times, I can´t believe that. The long cables were running over a multiple-electrical outlet, but the short cable runs over the same place, so that can´t be it, can it? In fact, I´ve got the router sitting right on top of it for lack of a better place. I repeat, there has been absolutely no problem since I got rid of both of those longer cables. And before I ditched them, I tried them a couple of times more, just to make sure. They both work in the original wired computer and don´t work in the new computer, with the same short cable plugged into them that I´m using now.

I can´t explain it.

Well i appreciate your help but this is now cracking me up. I've had another go & failed again. I brought the upstairs PC downstairs, (as the phone wires don't reach that far), & connected to the internet without any problems. Did windows & anti-virus updates & installed a firewall too. At least i know that the PC DOES connect to the internet now.

Did all of the things you said in your last post. I'd actually done everything correctly before on my other 2 previous attempts so there was nothing new that i came across in the process, (apart from. along the way, creating a home network set-up disk) by choosing that option in 'Network set-up wizard'. After running the wizard on both PC's, they both state that required hardware for home networking is not connected. The 'Network cable' icons in the task bar's of both PC's still have red crosses on them, & when i place the curser on them they state that, " network cable is unplugged".

I went through B.T. Broadband help, of how to connect 2 computers on the same internet connection & it's very extensive in it's instructions but NEVER ONCE mentions about connecting a ROUTER! So i've connected the PC's just through the ADSL modem AND tried it through the router & still, after the network wizard has told me everything has been successful, both PC's still tell me that i have not connected the network cable. It IS connected & i've tried 3 different cables now.

I borrowed mt sister's PC & tried all combinations, ie, connect 1 to 2, 1 to 3 & 2 to PC 3, & they all told me the network cable is unplugged when it is definitely connected up.

The downstairs PC is still 100% OK & says the internet connection is shared. In 'My network places', all the details are correct, the workgroup is the same, i've enabled file & printer sharing on both PC's & done everything i can think of, but still to no avail.

The only thing i must be doing wrong is plugging the wrong cables in the wrong places, or not in the correct order. The answer to all this will be very simple when i finally do it.

I'm not too bad working on applications with computers but it's the hardware i'm hopeless at, i've not learned anything at all about it yet. We have cables everywhere & like i said, some short ones left over (from the router kit). Also, i'm still not sure WHERE to put the router! Do i connect it from the downstars PC then into the BT ADSL modem? Or, out of the modem then into the router? Or, out of the upstairs PC?
Do i use a micro-filter for the PC upstairs? There is one downstairs & i have a spare one. There is a grey wire coming out of the back at the base of the downstairs PC absolutely going nowhere at all. Could this be for a dial-up connection? There is a phone wire coming out of the upstairs PC & there seems to be nowhere to put it after i've connected all the other things together. The downstaris PC obviously does not need this loose grey phone wire at the moment coz everything is fine.

So. i've got hardware disconnected but there are no more holes for any more wires to plug into. At least the PC upstairs DOES connect to the internet & is up to date now. It can't connect now of course because it's back upstairs again poor thing.

Any more suggestions would be greatly appreciated. (Apart from, "go away") Cheers!

[zeroth]

Cozzy, let me clarify just one point. You say you have connected 1 to 2, 2 to 3, etc. Are you plugging the cable from computer to computer or both computers into the router? And with all the verbage on this thread I can´t see where you mentioned the O/S. Is it XP?

[cozzy]

Yes it's XP. We are connecting the cable directly from one computer to the other. At one stage we had the modem connected to the router but i can't remember how! But still, for definite, we have always connected the network cable out of one computer into the other via nothing. Wish i could find a really simple drawing on the web somewhere. I've looked but just come across really complicated set-up's like offices etc. I'm not sure what goes where!

I'm nearly sure i'm setting it up correctly, could it be driver problems? Do you need drivers to enable the network cable to activate? If so, will the drivers be on the original windows XP cd's that came with the new PC's? After saying that, a full installation has been done on both PC's in the 1st place.

Do i need to connect the upstairs PC to a separate phone socket? because there isn't a phone point upstairs. Or do i connect the phone line into the router or into the ADSL BT modem? Do i use 2 microfilters? If i could find a simple drawing of 2 computers connected together (so they can both access the internet at the same time) i would be OK. We don't want printer & file sharing or wish to set up a massive network. All we are trying to do is enable BOTH PC's to be able to connect to the internet at the same time through the same connection. They both connect to the internet & work 100% OK when set up separately, but only the downstairs computer can connect to the internet when i've got it set up as a network with the cables connected to both PC's.

If i SWAP the PC's around & bring the one upstairs down & vice versa, then still, whichever PC is downstairs will connect to the internet but the upstairs one will not. Both PC's tell me a netwok cable is unplugged & whichever PC is upstairs just continues to try & dial up but cannot find the server. Then a red box appears telling me to plug in the network cable, but i can go no further coz it's plugged in. I've tried 3 network cables & 3 PC's so far.

Wondering what the simple answer is going to be. Cheers.

...Finally, after many wasted hours and much less hair...

:lol: yeah, been there & done that too! ;) It almost sounds like an attenuation issue, but unless the "long" cables where just that but taken to an unreal level (for residential implementation anyway), that wouldn't be it...unless the custom made cables really are the culprit, and their "fault" doesn't come into play with the shorter cables? You're right, that is a real hair puller! Glad to see you got that one solved! ;)

[cozzy]

Solved? No, nothing has been solved yet! The network cable is 5 metres long is that too long? Could that be the problem. I did all the things on the link below from CSCGAL & in the process, updated the drivers for the local area connection. But still, there is a red cross on the local area icon in the tray saying the network cable is unplugged. When i go into BT properties, select networking then advance i noticed the opion box, "enable print & file sharing with another PC" to be unchecked! Yet, when i ran the wizard it said it was enabled! I pressed "install" but it said there are no drivers installed for this option so i had to cancel. Strange. The next time i tried, it said OK but it will not come into effect until the next time it' dialled. So i disconnected from the net & connected again but the cable is apparrently still unplugged!!!!!!! It is plugged in..........HONEST. I've just tried it on all 3 PC's & they all say the same. I've got an old PC in the attic & gonna try that tomorrow.
