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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1256158 Title: BCM4360 High packet loss at 5GHz To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1256158/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
