aubergine, thank you for testing the newest mainline kernel. The next
step would be to bisect from Quantal to Raing, in order to identify the
commit that caused this regression. Could you please do this following
https://wiki.ubuntu.com/Kernel/KernelBisection ?

Title:
  14e4:4331 Broadcom BCM4331 unusable with Raring kernel 3.8.0-19

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I'm using a MacBookPro 8.1 with BCM4331 and it's linux driver b43.
  After upgrading to Ubuntu Raring with kernel 3.8.0-19 my wirless network device is nearly unusable.

  List of issues:
  - After suspend the wireless network connection doesn't go online again. The known network isn't found without changing the distance to the wireless network router.
  - Sometimes after reboot the wireless network connection doesn't go online without changing the distance or place
  - iwlist scanning shows only 25% or less of all physical available networks. Wireless network performance is bad.

  I'm using the old kernel 3.5.0-27 from Quantal Quetzal again and the
  wirless network is working fine again. None of the issues above are
  present.
