Title:
  14e4:4331 [Macbook Pro 10,1] Extremely high packet loss with BCM4331
  wireless

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  When using the b43 driver I can bring up the wireless. I see fewer APs
  then expected when scanning. I can connect to an AP, but any attempt
  to use the network connection results in packet loss of nearly 100%.
