Title:
  Network Manager fails to connect to any wireless network

Status in “network-manager” package in Ubuntu:
  New

Bug description:
  I can't connect to any networks. Even when i set-up an ad-hoc network
  it fails to connect. I tried both the STA and the b43 driver but the
  problem persists. Wireless networks are listed.

  When I try to connect through the command line I get the following
  error message:
