What do you get from:

iwconfig

Note that on recent kernel, we don't have wlan0 device but some strange name so you need to either rename it to wlan0 or use that name. I build and try 4.8.1 and its show up, will do some brief test later.

Here I am sorry for the delay.

iwconfig

ppp0      no wireless extensions.
eth0.101  no wireless extensions.
bond0     no wireless extensions.
eth0.104  no wireless extensions.
eth0.102  no wireless extensions.
tun0      no wireless extensions.
lo        no wireless extensions.
eth0      no wireless extensions.
br0       no wireless extensions.

What does it mean:

 

BTW: it happen to me too - no wireless at another boot so this could easily be is a power related problem. Check other topics for hardware hacks to fix this.
