(solved) bug report: failure with Ubuntu 20 on HP Z230 (again: this repo does not support the 8811au chipset. See: https://github.com/morrownr/8821au-20210708 )

[keithbriggs]

I've got an HP Z230 desktop which ran an earlier version of this driver under Ubuntu 18 without problems. I upgraded to Ubuntu 20, and now I cannot get the latest driver version to work. I even bought a new dongle, the AWUS036ACS was was claimed to be tested and compatible. The transcript below seems to show that installation worked without problems. I did "sudo bash ./install_driver.sh" and got a success message. I include the other requested output below. The device is showing up with lsusb. I would appreciate any suggestions as to what to try next.

Hi @keithbriggs

I even bought a new dongle, the AWUS036ACS was was claimed to be tested and compatible.

The AWUS036ACS uses the 8811au chipset. The proper driver for the 8811au chipset is:

Thanks very much - it's working now!
