Got the firmware in the right location? /lib/firmware/MT7601u.bin This guy got it working, albeit without WEP https://github.com/Yackou/nixie-radio/wiki/mt7601u-compilation >Do I go back to the old pre-4.2 driver? Would it react differently to >the >current one? Might have to go back. Although I did read that this particular firmware is missing from linux-firmware and that simply putting the blob in the right place fixed it for some Ubuntu distros. The post I saw had your device listed as working out of the box on Ubuntu 15 and some instructions for patching earlier releases. Apparently this is a popular problem. https://github.com/raspberrypi/linux/issues/1090 Usb hotplugging of a NIC, its kind of a funny concept. Trusted networks don't necessarily like that kind of quick change artistry. IMO usb has a shifty history of tracking and managing a hid Endpoint (device) to endpoints (buffers) Pi boards with different revisions, plus throw in systemd targets to boot and your looking at a clusterfork about to happen. The general tone is its not worth the time because better dongles are out there. You could see what wpa_supplicant shows systemctl status wpa_supplicant.service -l Or post the output of uname -a and ps xawf -eo pid,user,cgroups,args for the bigger picture. I'd bet on the firmware blob tho. Thats an issue with a lot of history in Linux and it does look like there is a working one out there.
