Title:
  BCM4360 High packet loss at 5GHz

Status in “bcmwl” package in Ubuntu:
  Invalid

Bug description:
  I have an ASUS PCE-AC68 adapter (BCM4360 chipset), running under
  13.10, kernel 3.11.0-13-generic x86_64, bcmwl-kernel-source
  6.30.223.141+bdcom-0ubuntu1. The AP supports 802.11a/b/g/n/ac.

  The card and adapter work perfectly when connected in the 2.4GHz band
  and 5GHz low channels (36-48). When connecting at 5GHz high channels
  (149-161), there are no obvious errors, but packet loss to the gateway
  is extremely high (50-80%). This behavior is very bursty, alternating
  between no, and total packet loss on a timescale ranging from a few
  seconds to a few minutes.

  Power management is off, and syslog/kern.log don't provide any useful
  clues. Based on the observed pattern of the packet loss, and the
  performance of other 5GHz devices connected to the same AP, I don't
  think it is an interference issue.

  I'm unsure as to how to proceed with generating some more useful
  logging, so any suggestions would be appreciated.
