Public bug reported: Pre-18.04, I had to download and install the module for my TP-Link T4U USB WiFi adapter manually. With most (not all) previous updates, the module would be incorporated in the update automatically.
With 18.04, this module is now included in the standard repository, which I appreciate. However, every time I do a version update ( twice, from 4.15.0-44 to 4.15.0-45, and now 4.15.0-45 to 4.15.0-46), the module is no longer operational following the update. I expect the module, now that it is in the standard repository, to be incorporated in the update every time. After an update, I can issue a command lshw -c network and it shows only my onboard wired adapter. If I connect my wired adapter and issue the command sudo apt install rtl8812au-dkms I get the response that the current version is already the newest version, and nothing happens. I need to first remove the current module, then reinstall it, and then reboot. sudo apt remove rtl8812au-dkms sudo apt install rtl8812au-dkms reboot The module is then functional when the system starts up again.
