I looked in the device manager and I saw the ethernet driver and all the WAN drivers, but I saw none for wifi and when I tried to update them it said all of the drivers were up to date.
It could be an issue with the actual antenna for the Wifi, are the Cables coming out of the Antenna clearly labled which one is 2.4 and 5ghz? as well as the ports on the back of the Motherboard itself? if not, try both ports on each plugin, or try only using 2.4 or 5
Have you plugged your PC into an Ethernet and updated Windows Via Settings? after a PC is "Reset", all the framework updates are uninstalled and can't be reinstalled until a User permits it to with an internet connection
Also look inside the plugins on the antenna and see if the little copper wire coming out is bent at all, I know Coax cables are always touchy and need an aligned connection
Check device manager again after you've tried both of these things and let me know If/what changes
worst case scenario, you might need to buy another antenna, or you can have the guy you bought this PC from do it for you, seeing as it was DOA
if possibly it's a software error and nothing physical, a fresh install of Windows 10 always fixes most of those, although that requires wiping your PC and is usually a time consuming step
