I also have an older TP-Link TL-WN321G stick. It does work, but only connects with some trouble and retries when I boot. After I get it to connect, though, it works more or less normally.
Since I don't normally have a cable-LAN connection on this computer, this is important for me to fix.¹ Thoughts greatly appreciated.
¹Now that I got wobbly windows working, I can work on the next-most-important problem.
