Realtek PCI-e Network Controller Not Detected
#1
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).

You shouldn't download copies from a Torrent file, because they could be damaged or altered in some way, always use a DVD, from a friend, from work, wherever, but of course, use a legal key all the times.

I had same problem with my sony vaio wireless (My wired connection was working fine), I downloaded a wire less updated driver from sony website and it worked after installing it. Your problem sounds to be software related. It should be solved easily, you just need to find out right driver setup.exe for your hardware which is compatible with your current OS. If you want to know more details please visit here network controller not found
