I tried everything, searched forums, looked at the Dell support sites and downloaded some drivers from there, and downloaded the N4050 drivers CD iso, but nothing worked. This is so frustrating that I don't even know what to try next.
It will difficult to find "N4050 drivers CD iso" as you mentioned. But still you can try Dell System Detect or Dell System Software Utility to analyze your system. Or you can use the online device detecting application provided by dell. You can find more information here. Otherwise you can try other commercial driver detecting applications such like Driver Detective, etc. Or probably if you know the driver information dell site itself provide all the necessary device drivers. 2b1af7f3a8
