Hello everyone,

So I know that this a question that has been asked a bunch of times but nothing is working and I am getting pretty frustrated. I've been using a Netgear Nighthawk router with my PC but I am still getting too much interference/lag when gaming so I decided to switch to a wired connection. I ran a cat6 ethernet cable from my PC to my router. Went to switch from WIFI to ethernet on my PC and it wouldn't detect the ethernet cable. Usually, under network adapters there would be a red X on the Realtek Ethernet Controller (when not plugged in) but the only thing listed is my netgear wireless adapter. My buddy told me to update the driver for the Realtek Network Controller...only problem was that it is not listed under Network Adapters in device manager whatsover. Its gone. When I try to update the Realtek driver through the MSI website (my mobo brand) I get the well-known error message "The Realtek Network Controller was not found. If Deep Sleep Mode enabled Please Plug the Cable". By the way, there is no "ethernet controller" under "other devices", otherwise I would have used that fix already. Someone said to go into msconfig and change to "normal startup" , only problem is that after restarting it goes right back to selective startup (and I've tried to troubleshoot that also). When I get home I am going to try and re-sit the RAM to reset the MOBO. If that doesn't work maybe I will reset BIOS (even though I am not sure how to do that).

Any help will be much appreciated! Thanks!
 
Solution
Make sure your adapter is listed in the BIOS (eg as a possible boot device). You might also want to turbn off "Quick Boot", disconnect your hard drive(s), so BIOS has nowhere to boot from - this will leave all devices discovered on the screen.
