Hi - I'm having exaclty the same issues as described in this thread. I'm on Windows 7 Premium 32-Bit and my Network Controller is Nvidia. Anytime I use applications on Facebook, stream a large movie or play an online game my connection drops and I have to Disable/Enable my Ethernet connection. I originally upgraded from Vista so I went back and ran a full install. Now there's now nothing on my PC apart from Windows 7 and IE8 but the problem remains. I tried disabling DHCP and using a static IP address but this made no difference. Has anyone tried the suggestion in the post above yet and does it work? If so I'm going to try it after work as this problem is driving me nuts lol!
