Public bug reported:

Occasional the wireless network connection stops working. If I then disable and enable networks using the network applet or the following command the whole PC slows down:
> sudo systemctl restart NetworkManager.service

I know of only two ways to resolve the problem: reboot and suspend.
The fastest way is doing suspend followed by resume.
