Title:
  Broadcom 4313 causes heavy interference with wireless clients after
  13.04 upgrade

Status in “bcmwl” package in Ubuntu:
  Fix Released

Bug description:
  After Ubuntu 13.04 upgrade, other wireless clients cannot access my
  WPA2-AES-PSK home network. They encounter high packet loss when
  physically near my Ubuntu system, but function fine when physically
  close to the wireless router and away from my system or when my system
  is off. My system appears to be causing heavy interference with the
  other clients.

  My wireless adapter is a Broadcom 4313 (built into the HP G72 laptop).

  Interference starts on boot and runs continuously until poweroff, even
  when my system should not be transmitting or receiving network
  packets.

  This began happening just after upgrading to 13.04, and did not happen
  with earlier versions of Ubuntu. I have been updating daily.

  The wireless network is visible (not hidden SSID), and in mixed
  802.11n/g mode.

  I do not see unexpected network traffic on the wireless network card
  when running Wireshark on the offending system, although I can only
  see the ethernet packets; I cannot seem to put my card into monitor
  mode.

  If necessary, I should be able to get a third computer capturing
  packets in monitor mode to see if my system is flooding RF packets,
  but that would require a bunch of time to set up.
