Thought I'd throw this out to the community to see if anyone else has seen this. My wife's Windows 7 (32bit) box can't browse the Internet through the VOIPo supplied Linksys RT31P2. Here are the details.

I bricked my WRT160N (don't ask), so I promoted the RT31P2 to be the gateway router. I get better call quality this way, so I thought I'd like to keep this set-up. But since then, her PC can not browse the Internet.

Her PC shows an Internet connection and can resolve DNS. Pings and tracert work as well, so it's only HTTP that is blocked. I removed virus scanners and firewalls to no avail. She's being assigned a valid IP address and her default gateway and subnet are correct. I've even reinstalled Windows. What convinces me it's not her PC is that she can browse just fine when I assign a static IP and put her in the router's DMZ.

Furthermore, my Windows 7 (64bit) PC, my laptop running XP, two Ubuntu boxes, the WII, the Sony television, and our Blu-Ray player are all connecting just fine. In fact, her PC behaves normally when I dual-boot it into Ubuntu.

So obviously it's some incompatibility between Windows 7 on her PC and the RT31P2. But what?

Thought I'd explore it with you guys before I go the BYOD route.
