[ubuntu] Atheros AR9271 flaky connection, Ubuntu 18.04.2 LTS

Hi,

I am running Ubuntu 18.04.2 LTS on a Dell Optiplex 9020 with a Wireless N USB Adapter w/ External Antenna (Model: TPE-N150USBL from ThinkPenguin.com), and my wireless connection is very flaky. The connection is fast when it works, but frequently, suddenly--and seemingly randomly--drops out. When it drops out, sometimes I will get a '?' tray icon in place of the wifi signal strength indicator at top-right and other times I will still have a few bars of signal strength but no connectivity.

My MacBook is sitting right beside the antenna of my wifi adapter and has no connectivity issues; it always has a strong signal strength and never disconnects.

The output from wireless-info script is here http://paste.ubuntu.com/p/DyTDXMvq95/ and is also attached as a tarball.

Any suggestions on how I can troubleshoot this issue?

Thanks in advance,
Malcolm
