After updating my network-manager, my wired connection continued to work, but it shows no notification; the double arrow is also missing, and the network manager just shows that "no connection" icon. How can I fix this?

  • @Pilot6, not a duplicate. Connection was working fine, just the notification was off. – Waldir Leoncio Feb 02 '16 at 19:52
  • But the problem and the solution must be the same I guess. – Pilot6 Feb 02 '16 at 19:57
  • @Pilot6 I appreciate the effort to avoid duplications on the site, but aside from restarting the network manager (which is not part of the solution, just a shortcut for a computer restart), I don't see similarities between the proposed solutions. – Waldir Leoncio Feb 02 '16 at 20:29

Edit your NetworkManager.conf file. One of these two commands should work, depending on your Ubuntu version (the first command worked in my 14.04 installarion).

gksu gedit /etc/NetworkManager/NetworkManager.conf

gksu gedit /etc/NetworkManager/nm-system-settings.conf

The opened document should have these lines:

[ifupdown]
managed=false

Change them to:

[ifupdown]
managed=true

Finally, you need to restart your network-manager. Do this at the terminal:

sudo service network-manager restart
