I tried all of those things and as predicted after shutting off my computer and turning it back on, Windows 7 did not connect to the internet and the only way to connect it is to disable and enable the driver...
I have the nForce 650i SLI Ethernet and it's not staying connected to the internet after restarting/sleep mode the computer. I have to disable and enable the driver in Device Manager to get it to work again. I have the latest drivers (15.51). Anyone know what to do? :confused:
