Similar on my old Acer Travelmate 5720 after an update from 14.04 (where I didn't have any issues with this lately): https://forum.ubuntuusers.de/topic/wlan-schmiert-immer-ab-nach-update- von-14-04-a/#post-7581108. This is in German, unfortunately, but I hope the console output there is still of some use.
