I've tried to search on forums but I'm not able to find a clear solution to this problem.

I have installed 16.04 in my laptop, and WiFi was working well until an automatic upgrade. On Grub the actual version I'm running is 4.8.0-52-generic

Succesive upgrades (4.8.0-56, 4.8.0-58 and so...) not activates WiFi and I don't know how to activate it.

I'm thinking on downgrade until .52 and then try to upgrade directly to latest version, but I'm so disoriented, what I have to do? Downgrade or patch?

The output of sudo lshw -C network is:

The only way for you to have the driver mt7630e working in 4.8.0-52 is that you compiled the driver from source code. You compiled it for the currently running kernel only; that is xx-52. Please reboot and select the latest kernel version you have available and re-compile:

cd Downloads/MT7630E

...or wherever you downloaded the files,

make clean
make
sudo make install
sudo modprobe mt7630e

Your wireless should now be working.

Whenever Update Manager offers a later kernel version, after the requested reboot, repeat the process.

  • Thanks for your help, but it doesn't worked at all. To work properly with wifi (networks in general) I still have to start with a previous kernel version. I'll try to reinstall complete system some day, I think. Thanks again! – estemon Oct 26 '17 at 06:00
