Status changed to 'Confirmed' because the bug affects multiple users.

I have been having trouble with this as well. It happens occasionally for me...usually after a long period of inactivity. Restarting the network manager will bring everything back to life:

service network-manager restart

I haven't tried reinstalling the network manager yet.

Service network-manager restart does not fix the problem for me. The only
way I have found is to reboot. I tried several other suggestions in other
peoples posts that have a similar problem and none have worked. I have
reinstalled network-manger with no change.
