I can connect to network, but the computer cannot find the internet.

[crow1307]

I am running a network at my home of 4 computers. The other 2 days ago I noticed that I cannot connect to the internet from the laptop that is connected to the network. I can still access the shared files and folders on the network, but I cannot access the internet. Whenever I click on internet explorer it gives me a message that the page cannot be displayed. This also happens when using firefox. I have already checked and reset winsock2 and my tcp/ip. What can I do to restore access to the internet?

pls check u r proxy settings

What am I looking for with my proxy settings?

[crow1307]

I do not have internet explorer using a proxy server. This problem is not limited to IE, it does the same thing with firefox as well. My computer is running very slow, and when i bring up my software for the wireless card it tells me that I am connected to the network but not the internet. I also have all the same problems when I connect directly to the router. I have tried resetting my system and that did not work.

You've left out everything we need to know.
What OS(s)? What hardware?
Post ipconfig.
Router? ISP?
Run a spyware scan.

I'm running windows xp on the laptop. I have a 2wire gateway modem/router that was provided to me through at&t. I ran a virus and spyware scan that did not pull up anything. I will run one again tonight and post results in the morning. I am using AVG Anti-Virus for that. If you know of anything better and preferably free let me know. I am using a linksys wireless card, but also have all of the same problems when I plug directly into the router. The ip config is as follows:

Windows IP Configuration

Ethernet adapter Local Area Connection
Media State . . . . . . . . . . . : Media Disconnected
Ethernet adapter Wireless Network Connection 3
Connection-specific DNS Suffix . : gateway.2wire.net
IP Address . . . . . . . . . . . . : 192.168.1.68
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.254

If you need any further information please let me know so I can resolve this problem as quickly as possible. I will be checking this several times throughout the day.

Do the other computers show a similar pattern for the IP address (i.e. 192.168.1.???). Is the gateway the same?
In Control Panel/Internet options, what is shown under connections?
Can you ping any web sites?
Try ping www.yahoo.com from a command prompt.

[crow1307]

All of the computers on the network show a similar patterin for the IP address. The gateway is the same for all of the computers. Under network connections from control panel I have one for Wireless Connection 3, one for Local Area Connection, and one for 1394 Connection. I'm not sure what the 1394 one is. I cannot ping www.yahoo.com from the command prompt. When I try I get a message saying "ping transmission failed : error code 5." I get the same message when I try to ping the gateway or one of the other IP addresses on the network. Also I ran another scan last night with AVG Anti-Virus Free and it did not pick up any infections. It also scans for spyware. The version of AVG is 8.5

[hughv]

1394 is Firewire, and that's OK.
All the other info sounds good. so this might be a firewall issue. If it's McCaffee, just uninstall it. Any firewall that blocks you without telling you is a piece of crap.

I was running McAfee on the computer. I got a message right before all this happened that said my McAfee subscription was up and that I needed to reinstall it. I thought that was a bit wierd, but I went ahead and tried to reinstall it. After that I think is when all this crap started. I had the shortcuts on my desktop, but whenever I clicked them they would not do anything. I went to the add/remove programs from the control panel and nothing from McAfee showed up. I went and deleted the McAfee folder from off of the c drive myself. other than that I have the windows firewall turned off so that shouldn't be an issue and I don't think the AVG is running a firewall.

[crow1307]

Ok... so I figured out my problem. I had previously ran McAfee on this computer. I tried to delete it with the Add/Remove Programs feature from the control panel to get rid of it, but no McAfee software showed up. I then deleted all of the McAfee folders form the computer and the problem still persisted. I found out that even after deleting all of these things through add/remove programs or deleting the folders McAfee still had left some things behind on the computer. There is a McAfee software removal tool that can be obtained through the McAfee website. Once I ran this software and removed all of the McAfee software and restarted my computer all of my problems were fixed! I hope this helps anyone having this same problem.

i wanted to confirm you have some computers that have no problem with internet browsing while the laptop cannot.

[crow1307]

yes... that was the problem, but I had solved it.
