Public bug reported:
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.
