In setting up a Linux Mint 20.1 machine for my wife, we have a problem that the wired networking does not find (name).local machines. I've played with avahi and some other things, but so far no joy ---- EXCEPT things work when I attach a wifi USB dongle. Sigh. And we thought we'd resolved enough things -- not really needing the .local machines -- that we could remove the dongle. But then the networked printer did not work either. Alex Pilon has suggested that maybe there are some firewall settings in the (wired) networking. However, I'm fairly ignorant of that sort of thing. Suggestions for diagnostics or things to try welcome. We'd rather not run the extra wifi if it isn't necessary. As an old one, it runs fairly hot. Re: printer. I tried 'sudo system-config-printer'. Got a different URI from searching, but no joy on printing. Says printer not connected. Similarly, took URI (different again) from my desktop (wired) machine. Same "not-connected" result.
