Hi Arend on debian is avaible only an experimental trunk of mainline 
4.12 and the RTL8723BS module is not activated i suppose , i tried this 
guide 
https://github.com/hadess/rtl8723bs/wiki/RTL8723BS-module-building-instruction-for-Debian-GNU-Linux 
but doens't NOTHING the make command ( obviously i installed all the 
necessary ) in the zip there are the firmware  *.bin maybe i must wait 
the 4,12 backports ....i could compile my own kernel but in this moment 
ain't much time.....
