Wireless not working in 17.10

I’m still on 16.10 because wireless didn’t work in 17.04. I have just tried 17.10 off a live CD and it’s still not working - for me anyway.

Hello
You should file a bug on launchpad against Linux.
This is unlikely to be an issue specific to Ubuntu MATE.
If it’s a Wi-Fi problem, then the whole Ubuntu ecosystem is affected.

I tried Ubuntu Gnome and Ubuntu Budgie and found the same problem, so I’m sure you are right. There are a couple of related bug reports on launchpad and a thread on here about it. Most of the advice doesn’t work.

However running an Ubuntu Budgie live CD, I tried the following.

Edit a file with:
sudo nano /etc/NetworkManager/NetworkManager.conf
type:
[device]
wifi.scan-rand-mac-address=no
Save it, then type:
sudo service network-manager restart

That worked, so I installed Budgie and repeated the above, it still works! Budgie hasn’t got the missing window decoration problem I’ve had with Ubuntu MATE either, so I’m sticking with it.
Thanks ouroumov!
