Hi guys i've been recently having an issue with one PC on my house which i can't seem to fix.

I lose my internet connection for no reason for very brief (about 1-5 secs) periods, i noticed it because my browser IE8 says something about losing connection to the server and then it automatically refreshes all my tabs, i tried to use firefox 4 and it has the same problem, because of this i can't download any files bigger than 20mb or so, which is quite annoying.

My modem is located on another PC and the internet connection is being shared over my local network, i am confident that there are no problems with my modem or my router as the other PC's on my house work just fine.

I've already tried reinstalling IE and firefox, also reinstalling my network adapter drivers and scanning my PC with NOD32, Malwarebytes Anti-Malware, Spybot Search & Destroy and Lavasoft Ad-Aware and i'm still facing the problem.

Additional Info:
OS: Windows XP SP3
Firewall: Windows Firewall
AV: Eset NOD32

I'd greatly appreciate any help you can offer as i can't locate the cause for this issue.

Thanks in advance,

If it's possible, here are some basic troubleshooting steps:

1) Is the problem computer a wired ethernet connection to the router, or wireless? If it's wired, try switching the ethernet cable with one of the working computers. If that doesn't fix it try another port on the router or switch (one you know works). If the connection is wireless, connect the computer via ethernet cable. These steps will rule out the actual network connections itself, especially since you have other computers working with no problems.

2) If step one didn't find the problem, compare all your network settings with a working PC. You can find most of the pertinent info in XP by going to control panel, network connections, Local Area Connection or Wireless Connection, then right click and select status and then support tab. Make sure both computers have valid IP addresses. Make sure that the problem computer isn't statically assigned an IP address that exists on another computer or network device (printer, NAS, etc)

If you can provide more details from the above steps, we might be able to find it.
