Using Ubuntu 18.04 and a TP Link WN722Nv2 USB to Wireless adaptor I have been unable to setup a WiFi hotspot.
I have tested the H/W on 18.04, connecting to a WiFi router, which works fine. I have tested the H/W on Windows 10 and it works fine as a hotspot.
The adaptor shows up as wlxd03745a3c52b. The networkmanager logging didn't show anything that meant anything to me.
I have created a script which produces the following results:
$ ./hotspot.sh

I've tried various combinations of WiFi security options but all produce similar results or references to 802.1x supplicant taking too long.
I'm running out of ideas and would be grateful for any suggestions. Are there other USB to WiFi adaptors that are known to work better?
