post the EFI folder + IOReg fie

Atheros are not supported beyond High Sierra therefore you'll need to restore IO80211Family.kext from HS. 

For Big Sur, you'll need to 1st disable SIP,  find and delete Snapshots, unSeal, then you can access /S/L/E.

You'll have to google for the instructions, I don't have it off hand. After that, you'll still need to patch it to be compatible.

Probably much easier to find a more compatible card.
