** Description changed:

  While connected to a 802.11n network, network-manager says I am indeed
  connected, but apparently I am not. Trying to ping the router, access
  the internet or somehow use the network doesn't work.
  
  Restartint the network-manager service, though, fixes it. The problem is
  that I have to do this EVERY time I reboot or resume from suspend.
  
  I found this bug report[1] at Red Hat that seems to be exactly what I'm
  experiencing.
  
  Cry.

+ 
+ WORKAROUND: adding the 11n_disable option to modprobe "solves" the
+ problem.
