Wifi has been working out of the box for close to 20 years now. On some computers with old Broadcom cards, you have to enable non-free drivers. What model are you using?

WiFi works fine if there are drivers for whatever WiFi chip you have.

Unfortunately there are no standards for OS to talk to WiFi devices like exist for many other types of hardware, so it’s not possible to make generic drivers.

Did you forget your WiFi password?

yes
