On Ubuntu 19.04 I had current rtl8812au (AC1200) and rtl8814au (AC1750) dkms drivers for my USB wireless dongles installed and running fine.
They both broke after I upgraded to Ubuntu 19.10.
I've been able to find a replacement/newer rtl8812au driver that works with kernel 5.3 on Ubuntu 19.10.
I haven't been able to find a replacement/newer rtl8814au driver that works with kernel 5.3 on Ubuntu 19.10.
Github.com has a number of rtl8814au drivers available, even some that proport to compile with kernel 5.2. I believe that I've tried about 6 different rtl8814au drivers from github, but none of them work, even though some of them do compile with kernel 5.3.
Does anybody know of a working rtl8814au driver that works with kernel 5.3 on Ubuntu 19.10?
It worked for me on my rtl8814au device, it should work for rtl8812au, rtl8814au, and rtl8821au devices. For some strange reason the driver didn't want to work until after a second reboot. I don't know why
Secure boot needs to be disabled in BIOS, check results for
mokutil --sb-state
With recent changes you need to
Reboot
