Which AV are you using? I set up a Win7 PC for a friend a couple of weeks ago, and could ping the world but connect to nothing, nomatter which protocol I used. Short version, once I removed the bundled Bullguard AV and replaced it with Microsoft Security Essentials, everything started working perfectly. Disabling it made no difference, I had to remove it. So, you might want to try removing your current AV and installing another, and Security Essentials is free and worked for me.
I'm using avast free edition. I removed it anyway. No difference.This post has been edited by kironohasama: Feb 21 2011, 05:59 AM
