Looking briefly I saw this bug:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=842422

Two workarounds:

 /etc/NetworkManager/NetworkManager.conf

adding

 [device]
 wifi.scan-rand-mac-address=no

to 

 /etc/NetworkManager/NetworkManager.conf

or kernel parameter
 
 net.ifnames=0

at boot.

Maybe not pertinent.
