1.Plug this USB dongle in PC.

2.Download from Mediatek last driver https://d86o2zu8ugzlg.cloudfront.net/mediatek-craft/drivers/mt7610u_wifi_sta_v3002_dpo_20130916.tar.bz2 , extracted the archive and:

$ cd ~/Downloads/mt7610u_wifi_sta_v3002_dpo_20130916

enp3s0    no wireless extensions.

I don't understand what's the problem and how do I install this driver?

  • There seems to be a regression in 4.4.0-79 compared to 4.4.0-78, and therefore the dongle is recognized only when hotplugged, and will not work after a reboot. With the older kernel everything is fine and dandy out of the box, alas a kernel downgrade on Mint 18.1 solved it. Upgrading to 4.4.0-79 is of low urgency anyway. Not the most elegant solution, but it works.
