Summary of the situation and next diagnostic steps

reported an XP SP2 machine that shows a link to the router at the command prompt but cannot reach the Internet, while other clients on the same router work. Earlier replies from indicate common Windows stack repairs were attempted and suggested ruling out wireless vs wired. Because the fault is isolated to this PC, the emphasis should be on adapter/OS-level causes (DNS, proxy, driver, services, IP conflicts) rather than the router or ISP.

Recommended diagnostic sequence (fast order to isolate the layer that fails):

Run basic network probes on the affected PC to see where traffic stops:

ping <router-ip>
ping 8.8.8.8
tracert 8.8.8.8
arp -a
netstat -rn

How to read the results and follow-on actions

  • Router reachable but public IPs not: look at traceroute to see the hop that drops. Check the router’s DHCP client list and logs for that PC’s IP and MAC; verify no MAC filtering or static block.
  • Public IP reachable but hostnames fail: this is DNS. Inspect the hosts file at C:\Windows\System32\drivers\etc\hosts and browser proxy settings (Internet Options → Connections → LAN settings). Temporarily set an explicit public DNS (8.8.8.8 or 1.1.1.1) to test.
  • Nothing outside router reachable: check NIC link lights, adapter duplex/speed settings, and reinstall or roll back the NIC driver. Confirm Windows services such as DHCP Client and DNS Client are running.
  • Intermittent or odd behaviour: look for IP conflicts (duplicate addresses shown by arp), third‑party firewalls/AV blocking outbound ports, or malware that installs a proxy—booting a Linux Live USB is a quick way to determine whether the problem is OS-related.

If these steps still fail, capture traceroute/arp output and router DHCP lease info and consider a system restore or clean network driver install. This targets the gaps not covered earlier in the thread while building on and ’s suggestions.

what OS are you using
have you tried opening a comand prompt
type ipconfig/relese
hit enter
wait for results
then ipconfig/renew
also try ipconfig/flushdns
what are the results from above?
when you try to connect, what error do you get?
also try connecting to the internet in safe mode with networking as a test
it also maybe winsock
download this program, make sure you click winsock and are downloading winsock

Are you connected wired or wirelessly? If wirelessly, can you check with a cable and see if you have the same issue?

Member Avatar for la1

did you try with safe mode with networking

do ipconfig/all
what is your ip

are you sure the cat5cable is staight through and not a cross over cable ?
when you remove the cable at the router a coresponding lamp for that connector on the router should go out and come back on when plugging back in, the same at the back of the pc

do you have any firewalls including xp's firewall
has this pc ever been infected
how is the pc running in general
