I “lost” my ralink usb wireless dongle in the upgrade to 11.4. I don’t know if you want to cover old ground, but search on the firmware. I needed to extract only two files and place them in folders I had to create for them. Having done that, my wireless is back to normal. I was using the very old rt73usb supplied by suse. Not in front of that computer now, I think it was replaced with a 2500 driver.
Off topic - the forum software looks different today. It’s brighter and more colorful. I just upgraded google chrome. Maybe that’s it.
