Ethernet adapter suddenly missing

It could be that pc is missing a signed driver for the ethernet adaptor. If so, sometimes the adapter is not seen at allI has this issue with a wifi adapter.

The first time I clean installed Windows I did get a message telling me I was missing a driver of some sort. I think it wanted me to put in a cd, but at the time my cd/dvd drive wasn't even plugged in so I didn't try. Somehow I got past that though and installed windows.

Not sure how to correct that if it is what's wrong.

I know it suck's but it's not the first time I have to do that. My mother replaced her MB once and 2 weeks later there's was no more On-board Ethernet working. Instead of returning the MB and wait I pop in a Pci adapter and it never failed since.

I read one solution online where someone bought a PCIe card and as soon as they installed it, the onboard LAN started working again. I'm going to lose my mind if that happens lol.

First you need to go on to web and find ethernet driver for that mobo, then you need to inject driver into Windows

Briefly reading about injecting drivers; it seems kind of complicated. And all the results I'm seeing mention injecting to a Windows iso or image, does that mean I would need to clean install again after injecting?

Unfortunately that didn't seem to work.

Microsoft PnP Utility

Adding driver package: e2f68.inf

There's either something really weird going on with my devices (which I don't understand how that's possible after clean install), or the on-board controller or adapter somehow broke in less than 1 week of usage.

Have you opened up your computer and tried uninstalling the ethernet card and reinstalling?

That will be difficult with an Onboard adapter.

Lol. Yeah the best I could do was disable/re-enable in the BIOS but that didn't work. I just bought a TG-3468 today so I'm going to install that later as a band-aid fix but I would still like to solve this, in case it happens to anyone else.

I suspect that this problem is caused by the Gigabyte BIOS. If you simply unplug the power, wait for 15 seconds, then plug the power back in, and boot the machine, then enter the BIOS > settings page, you should see the Intel Ethernet Controller reappear at the bottom. This should solve the problem.
