Ok so I upgraded my Dell Studio XPS m1640 from Vista 64-bit to Windows 7 64-bit. When I started it back up, I had to install new drivers for my WiFi which is the Intel(R) WiFi Link 5150. I had no trouble getting the driver for this. However, I tried to start up my internet and the computer notified me that the driver for the "Network Controller" was not installed. I have still not been able to find a driver that works for this and am unable to access the internet on this computer. I would appreciate any feedback! THANKS!
