I just got my PC back from the repair shop after replacing the motherboard, and now I'm facing some serious issues. I can't log in because it shows my username but none of the passwords are working. Plus, the only internet option available is to toggle airplane mode; there's no WiFi option. I've already tried enabling the hidden administrator account using "net user administrator /active:yes" and did a reset while keeping my files, but no luck. Has anyone dealt with this before? What can I do to get access to WiFi again?

Considering this is Windows 11, you may be running into issues because your login credentials were saved on the old motherboard's TPM chip. If you can't log in with your Microsoft account, you may need to do a clean reinstall of Windows. Just make sure you back up your data!
Have you checked if the new motherboard actually comes with built-in WiFi? Sometimes, if it’s integrated, it might need an antenna attached properly. If you need immediate internet, consider tethering your phone via USB to download the necessary drivers through Windows update.
It sounds like the drivers for your WiFi or network interface card (NIC) aren’t installed. I'd recommend taking the PC back to the repair shop and asking them to sort it out. You can also give them a little nudge about how they should've installed the drivers before handing it back to you.
Honestly, it’s best to get back in touch with the repair shop. They should inform you if there were significant changes made, and it’s their responsibility to ensure everything works before returning a system to you.
It might be worth checking if the old WiFi setup was a separate card or part of the old motherboard as well. If the new board doesn’t support WiFi, you could find yourself needing to buy a new WiFi card.
