I tried many times to install (via apt get, dkms, git clone) the rtl8812au driver for the alfa AWUS036ACH adapter. Internally (xps 15) I have a Intel Wireless-AC 9560 WLAN WiFi 802.11ac so I need the backport iwlwifi to make it work).

Including : Need rtl8814au driver for kernel 5.3 on Ubuntu 19.10

When I search on ifconfig, iwconfig or airmon-ng is not found.

It does appear on 'lsusb'. Also:

modprobe rtl8812au

got:

modprobe: FATAL: Module rtl8812au not found in directory
 /lib/modules/5.3.0-40-generic

I have ubuntu 18.4 on kernel 5.3.0-40-generic Also

 dkms status

and ifconfig returns only my internal Broadcast module:

PS: I also tried the kernel 5.3 but it didn't solve the problem immediatly and on my skylake processor was eating up all the battery. So the solution needs to be be using kernel 4.15+
