This also affects me on a late 2013 retina macbook pro (11,1) running under 13.10 (same BCM4360 chipset). I've tried both with the original 3.11 and with 3.13 (from mainline kernel ppa).

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.
