WIFI doesn't work after a fresh 4.0 install

[newtusmaximus]

If you have the Atheros AR3012 (shipped in some lenovo laptops like the z50 that i have) and linux lite 4.0 or ubuntu 18.04, you might have a problem with the adapter, and if you use the command dmesg you are going to get this error:
[sup]bluetooth: hci0: don't support firmware rome 0x31010000[/sup]

I found this solution that solve that issue...

1. Add the ukuu repo to your system:
[sup]sudo add-apt-repository ppa:teejee2008/ppa && sudo apt update[/sup]

2. Install ukuu:
[sup]sudo apt install ukuu[/sup]

3. Install the kernel 4.16.9 with ukuu:
[sup]sudo ukuu --install v4.16.9 [/sup]

4. And finally reboot

The problem with the AR3012 is caused by the kernel 4.15.0 shipped with Ubuntu 18.04 and linux lite 4.0 and the unique kernel i found  that solve that issue is the 4.16.9

pd: i'm not an english speaker so maybe the instrutions or the grammar is bad, sorry for that

Posted elsewhere. Might this help here also?
