Title:
  14e4:4727 [Lenovo G570 Notebook 4334] activation of wifi freezes
  system (Broadcom 4313)

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  upon activation of the wifi networks, my computer fully freezes. This has been since about 2 months. I have tried many time the different drivers:
  * brcmsmac
  * wl / Broadcom 802.11 Linux STA (via sudo apt-get install bcmwl-kernel-source)

  I did go through the guide at the wiki but got lost in the drivers part:
  https://help.ubuntu.com/community/WifiDocs/WirelessTroubleShootingGuide/Drivers

  I asked a question without sucess for solution:
  * http://askubuntu.com/questions/267510/how-to-prevent-system-freeze-on-wifi-activation
  * http://forum.ubuntuusers.de/topic/bitte-helfen-system-friert-beim-aktivieren-des/
