Since 2 days ago I can't edit any connections using network manager, because the "edit" button is greyed out. I tried doing a normal restart of the service to no avail.

Any suggestions?

Try this fix-for-error-network-device-not i think you got the similar problem as me.

Summary from linked content:

  1. Run in terminal - sudo /etc/init.d/networking restart

  2. Edit file - /etc/NetworkManager/NetworkManager.conf

  3. Change - managed=false to managed=true

  4. Run - sudo killall NetworkManger

  5. Now attempt to configure your interface

One quick work-around is to invoke the connection editor manually from the command line:


You'll get the same familiar edit screen. Worked for me.

u might need to unlock it, there might be an unlock button somweher in that window, if u cant find it try maximising the window and look for it, happened to me once :)

I checked and I don't see there is any unlock button as it is in other configuration options not related to network-manager. I Have done an upgrade and still can edit. –  Oscar Martinez Nov 16 '11 at 9:06
