      And yeah, that adapter driver was installed and working correctly until yesterday.

      What happens if you install the driver again ?

      What file or screenshot can I provide for better info on this?

      Post the output of dmesg on pastebin.com.

          Seems like the module is already installed and the re-installation fails. What's the output of

          dkms status
          

          dmesg that you requested:
          https://pastebin.com/mkfFKb2D

          I don't see anything related to the WiFi adapter here. By default RaspiOS will disable the WiFi if the ethernet adapter is connected, which is what I see from your dmesg . Have you tried booting without the wired network connected ?

            Yeah, I had to ethernet cable both Pis so I could change the config.txt file to:
            #dtoverlay=disable-wifi
            #dtoverlay=disable-bt

            I don't know what I'm doing but thought that was at least a way to get WiFi back again.

            Have you tried booting without the wired network connected ?

            Yes, and I received something like a "No wlan0 interface detected" on them both.

            I understand nothing. :D

              I see that xpad has been added for the latest kernel, but the 8812au has not.
              Remove the driver:

              sudo dkms remove 8812au/5.6.4.2_35491.20191025 --all
              

              and then try to re-install it again. If you get an error during installation, then post the log file from the build - dkms will show you where it is.

                The preview for this post seems to show extra large fonts a few times for some reason.

                That wasn't from me.

                No idea how that came to be.

                My apologies ahead for any unnecessary font weirdness on this site. :P

                  I don't know what that means.

                  I need something to copy and paste because I am too stupid to live.

                    OK, so it fails here and it's probably why it was not automatically installed during the kernel upgrade.

                    Try running

                    dkms install -m 8812au -v 5.6.4.2_35491.20191025 --all
                    

                    from the source folder and see if it gets installed.

                          Ah nuts.

                          Just realized you requested to install that from the source folder.

                          Sorry.

                          Have I done that correctly?

                            Yes, but I think it doesn't matter. Is the wireless driver still not installed ? You can check with sudo dkms status to see if it was installed for the current kernel (5.10.103).

                                It's still not installed. I wander though if you're not actually seeing the same issue with https://retropie.org.uk/forum/topic/34200/.
                                Add arm_64bit=0 to your /boot/config.txt , reboot and then try again installing the driver.

                                    Remove the module again with sudo dkms remove 8812au/5.6.4.2_35491.20191025 --all and re-run the installation, but just the last step.

                                      Think it took this time. :D

                                      Going to unplug my ethernet cable now and do this for my other Pi as well.

                                      Thank you so much Mitu!
