Public bug reported: After upgrading to 16.04 LTS, whenever trying to switch wifi access points (APs), network-manager "crashes" -- meaning that the applet no longer displays available APs and in their stead is a message "device not ready."
In case it helps, here are the wifi script results: https://dl.dropboxusercontent.com/u/13392425/wireless-info.txt. Note that this is bug different and distinct from Bug #1574347 (wifi dies on wake from suspend), and the reported fix for that bug does not help at all.
