Sometimes when I hibernate my laptop It's not able to connect to internet(neither ethernet or wi-fi) after waking up. The icon on panel says "Networking disabled" and can't be switched back on by clicking on it as it usually works. Next restart/hibernation/sleep always makes networking work again.

Notes: I mostly use ethernet on a network that is mac address specific and so far I haven't had same problem anywhere else.


I get this problem sometimes, here is how I fix it. Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:

sudo service network-manager restart

Enter your password, and press Enter
