I want to add WiFi functionality to a desktop PC with a USB Wifi convertor. Wich brand and/or type is the most likely to be recognised and used by Ubuntu Mate 22.04?
Or - provided I can find it in tthe documentation - wich chipset do I have to look for?
I have a Trendnet TEW-644UB USB WiFi dongle that has worked very well with Mate 22.04. I used it to to the initial rounds of updates after I installed 22.04 to a new machine where my workspace for assembly was not convenient for wired Ethernet. I don't know if this model is still available or not.
The u-tube chanal "Learnlinux TV" has a video called How to get WiFi working on Linux which gives a lot of useful information.
This link will take you directly to the part where he ( Jay LaCroix) talks about USB-WiFi dongles:
He calls the thinkpenguin USB adaptor(s) "relatively inexpensive". The cheapest one is 54USD. That's not cheap. If I buy 4 different ones, different brands, locally for say 12€, I'm still have 4 chances that ony one of them works, and still be cheaper off, while I can use the ones that do not work for other projects.
