[Bug 49221] Re: Unable to start applications after suspend/hibernation

[André Carezia]

Also, in my case, I can fix the problem issuing the commands below:

  sudo /etc/init.d/networking stop
  sudo /etc/init.d/networking start

As I use network manager, these commands affect only loopback interface.
I didn't check loopback interface before restarting it. Will do next
time.
