As far as I can tell the adapter simply isn't being recognized. I also tried creating a wifi connection, but that didn't work.
I also couldn't get linux-firmware-nonfree to install, which came up in some other threads I saw. I've gone through some other similar threads, but nothing seemed to work. I'm trying to get my desktop setup to get wifi with my new Linksys Max-Tream AC600 Wi-Fi Micro USB Adapter. I'm new to linux, so sorry if I'm a bit slow on the uptake here.
