for context i always used wi fi cause of the way my house is built i can’t use an ethernet cable, and i never had problems with it but just like 5 minutes ago i booted up the pc and the option to connect to wi fi is literally gone, even if i go to settings and then go into the network subsection there is literally no option for the wifi, like if my pc never supported it
If it’s a Dell desktop, power off. Unplug. Hold up the plug end and touch the metal ends of the plug with a finger to be touching 2 or 3 poles.
Plug back in, start, and maybe that Wi–Fi card will be showing again. (a known XPS-8930 thing)
