Got the solution Hey guys, I found your messages here because obviously I had the same problem, and I was starting to really think about a rollback to Vista or XP because my 100Mb fiber optic was totally like an old DSL and most of all, every browser was sooo slow (IE, Firefox, Chrome, etc). Of course it wasn't my connection, I tested that and my laptop was working very fine... and then, all of the sudden, the word "rollback" echoed in my mind. What you have to do is remove the shinny drivers you downloaded and installed, thinking they would be better and give you more speed, and rollback to default windows 7 driver (I run with a nForce and default drivers are from 2008 in Windows 7). My connection now runs like a charm (http://www.speedtest.net/result/586836297.png) and I don't see myself installing any nVidia network driver again... So once again : rollback to the default windows 7 network driver in the control panel - devices manager. Hope this helps !
