My network connections stopped working, I am unable to connect through a wireless connection, or through a wired one.
On the top bar, on network tab I get this message: No network devices available
And on System settings -> Betwork, If I click on options nothing happens, I only can create a new VPN network.
I have to mention that it worked fee days ago.
I have a Dell inspiron N5110 and I am using Ubuntu 12.10.
