Wifi doesn't work on 17.04

Question

After updating from 16.10 to 17.04, Wi-FI no longer works. I use the APPUSB150NAV2 adapter, which worked fine in 16.10.

I also tested with Ubuntu Gnome; it made no difference.

How can I get my Wi-FI working?

Open the NetworkManager file with your text editor:

sudo -H gedit /etc/NetworkManager/NetworkManager.conf

add lines

[device]
wifi.scan-rand-mac-address=0

Save and close file then reboot.
