Wifi Connection drops after exactly 10 minutes

Hi everyone,
I really need some help Please!

I have a very well updated Laptop running XP well patched with IE7.
I have run all the malware scans and there is nothing wrong on the PC.

After exactly 10 minutes of the PC being on, wireless internet connection is lost, BUT:

Signal Strength states "Excellent"

I can't access any website at all on the web. (Except for "Facebook" for some odd reason?) I can't access it
after the 10 minute mark but if I'm already on it, I can navigate thru it's site without being disconnected, don't
ask me why

I have tried the following:

- Dynamic and Static IP setting
- Turned on and off windows firewall and rebooted each time
- Ran all kinds of malware detection and virus scans
- Disabled power management on network card
- I've tried different PCs on the same network and they're fine
- Tried ipconfig release and renew
- Tried repair connection
- Tried netsh reset
- Tried FireFox and other browers
- Logging off and back in doesn't help, must restart the computer to get another 10 minutes

I'm at wits end, Please Help!

 

Do you have an IM programs? Do they drop after 10 minutes?

That facebook stays on makes me wonder if your DNS server is having an issue. I can't for the life of me imagine what would make a DNS server stop responding after 10 minutes but it sounds like something somewhere might be set to have a 10 minute lease.

This is just a regular home connection with your run of the mill home network equipment?

To test the DNS, try overriding the current dns setting (write it down to put it back after the test) with a temp DNS server for TESTING ONLY, like 4.2.2.2.

If you can browse for more than 10 minutes with that then there are some more steps for getting a good DNS server in. If that doesn't resolve it, there are a few other things to look at.
