Ubuntu: Ralink MT7601U (148f:7601) Wi-Fi adapter not working on Ubuntu 16.04


I have updated my Ubuntu desktop from 14.04 to 16.04 and my WI-Fi dongle stooped working. I've tried to follow the instructions on Ralink MT7601U (148f:7601) Wi-Fi adapter installation but it did not worked.

How can I make it work again?

Thanks guys.


I've ran the commands:

rfkill list all    sudo modprobe mt7601u && dmesg | grep mt76  

The result was:

[   85.231948] mt7601Usta: module verification failed: signature and/or required key missing - tainting kernel  [10822.191654] usbcore: registered new interface driver mt7601u  

Any idea of what to do next?


I disabled the secured boot and it's still not working The result of running again the previous commands are: [ 185.695417] mt7601u 3-4:1.0: ASIC revision: 76010001 MAC revision: 76010500

[ 185.712356] mt7601u 3-4:1.0: firmware, attempted to load /lib/firmware/mt7601u.bin, but failed with error -22

[ 185.712362] mt7601u 3-4:1.0: Direct firmware load for mt7601u.bin failed with error -22

[ 185.712917] usbcore: registered new interface driver mt7601u


The problem was apparently the kernel that was corrupted because other stuff did not worked as well. I erased Ubuntu completely and than reinstalled 16.04 and the Wi-fi dongle just works and no special installation to be done.

Thanks anyway for checking and putting your comments.
