While I'm not certain it will help, I found building and installing a driver from https://github.com/lwfinger/rtw89 worked on my HP 14" laptop running Linux Mint 20.1 (based on Ubuntu 20.04 code infrastructure).

It works for me! Thank's! I had one problem of this. There wasn't rtw89 directory but I created it manualy.

I should add that I've since found that I don't get a proper network printer installation to my Brother HL2270DW. I tried a USB ethernet (wired - fine), and a TP-Link TL-WN321G USB wifi dongle also OK, but a (new, tiny) TP-Link WN725N clobbered all wifi and popped up some messages that wifi disabled because of some problem with Realtek Renoir GPP Bridge. It seems there's a fight between internal Realtek and USB one. I suspect that I may have to play around quite a bit with printer settings and/or some of the options in rtw89 -- assuming it is running correctly for all aspects of the protocol.

After core update driver not working again. For fix it driver has to install again.

Yes. I found I had to reinstall after kernel updated too. Not a big deal, but an annoyance.

Also found that I have to use direct IP4 number to get to printer etc. still. I suspect there are still a few features lacking in the rtw89 driver.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
