Wipe is not an option, don't read further if you plan on suggesting it.
I don't necessarily think I'll get help here, but I love Lemmy and it constantly surprises me, so I'll shoot my shot.
The other day I downloaded and installed driver updates for my motherboard and then a BIOS update as well. I'm paranoid about stuff so even though I'm experienced with this stuff for the most part I still followed the instructions step by step to a T and made sure it was for my correct motherboard.
After rebooting my internet wasn't working so I checked device manager and it was showing an error for my network adapter which along with other drivers was among the updates. So I tried various things with that for hours and never made any headway. Internet over bluetooth doesn't seem to want to work or be detected, my phone won't tether Internet over USB correctly either or it's not being detected by the PC. So I ordered both a PCIe LAN card and a PCIe WiFi card. The lan card uses the same drivers apparently and so it's just an additional error'd out Realtek Family Whatever Whatever; the Wi-Fi card doesn't appear at all. Both the lans do light up during booting and in BIOS but shut down once Windows loads it's drivers.
I've rolled back my system as far as I can which unfortunately do to trying to many other things before the rollback I could only go back to installing one of the first drivers. I've tried different drivers and different BIOS. I've run SFC but it required Internet for some files, DISM requires Internet or a install image but I don't have one and don't have room on my phone to download one. I've tried in safe mode and I've probably tried 30 other things to no avail that escape my mind right now.
Any thoughts will be appreciated. Thanks for reading.
