I am experiencing this as well; same macbook pro (11,1) as Julien. I experience many occurrences of this in /var/log/syslog: ERROR @wl_cfg80211_get_station : Wrong Mac address
Eventually, the card disassociates, and fails repeatedly to reconnect to the AP. Sometimes it succeeds, but will fail again soon after (the driver remains in a bad state). I have a very rough "workaround", reloading the wl module, but it's time-consuming and is no real fix. After running this, the card reassociates on its first try, then works well until the problem re-occurs. This indicates to me that it's a problem in the driver, not something to do with any state on the card. sudo service network-manager stop sudo pkill wpa_supplicant sudo rmmod wl sudo modprobe wl sudo service network-manager restart -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bcmwl in Ubuntu. https://bugs.launchpad.net/bugs/1256158 Title: BCM4360 High packet loss at 5GHz Status in “bcmwl” package in Ubuntu: Confirmed 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.
