Public bug reported: I have researched all possible solutions. The correct driver rt2800pci is installed correctly out of the box. No hardware faults. Wifi works on Ubuntu 14.04 with rt2800pci, but better with rt5390sta fixed for Ralink wlan driver found here https://github.com/wapmesquita/2011_1007_RT5390_RT5392_Linux_STA_V2.5.0.3_DPO_v2
This fix does not work for 16.04. I can sometimes regain functionality for a limited time by using network manager to un-check "Enable Networking" and the recheck it. I have tried connecting by Ethernet cable and get the same behavior.
