Comment 4 for bug 1438422

Tested 3.16.0-29 . Bug behavior appeared to be the same.

It might also be worth noting that sometimes, even when I re-enable WiFi, the network manager does not recognize available networks. However, I can connect if I choose to connect to a hidden network and then select from a list of potential hidden networks one that I know is active and in range. After that successful connection, network manager begins displaying that and other networks properly. I have assumed that this is just to do with the messy way in which the OS thinks the WiFi has been turned on or off by hardware switch, but maybe it's some kind of clue by itself.
