Problem is back in 5.4.0-62-generic. That version was recently released by Ubuntu and installed on my system during a regular update. However, when I run it and with that TP-Link AC-600 installed, I am again seeing the symptoms I observed in my original bug https://bugs.launchpad.net/bugs/1907764 .
- Networking won't start. Network Settings shows "NetManager not running"
- "ip addr" just hangs
- Firefox never displays a window
Rebooted under the developer version 5.4.0-61-generic, and things are working again (my AC-600 is still enabled and connected).
