Here is the truth of the matter..
If you're here, one of two things has happened. The first possibility is that you just need to uninstall drivers and reboot the machine as described above.
The second possibility is you've been fked over by Windows 11 because their developers are goofs. There are over a dozen WiFi adapter models that we've identified as being incompatible with W11. This is typically a problem in slightly older machines, but long story short - there is no resolution and there will never be one. If the basic steps do not resolve the issue, then you will need to buy a WiFi dongle and bypass the WiFi adapter that's built in.
For the record, we've tested no external dongles that failed to work. This is limited to onboard WiFi hardware in laptops, All-in-Ones, and some desktops.
