Let me wrap my head around the exact situation here... There is not a packaged .tar driver file you can download to your windows computer and then transfer over and extract it in the proper place in the Linux computer?
There is simply no shown detection any of the 3 USB wireless adapters, thus no "add driver" option. On my own PC I have found two files that I decompressed,
rtl88x2BU_WiFi_linux_v5.2.4.1_22719.20170613_COEX20170518-4444.tar
rtl8821AU_linux_v4.3.14_13455.20150212_BTCOEX20150128-51.tar
However, where to put them and how to make Linux work with them I know not, and think the Kubuntu solution would be better.
