Qualcomm Atheros Device 0042 (rev 30)

[vagner]

I Have a new laptop:

Lenovo ideapad 300-15
Intel i5 6th generation

Running Debian Stretch/Testing. And my wireless card does not work. I 
have tried all sort of solutions. Including compiling with backports. 
But, my kernel is new, using the same backports new version.
How can I make this nightmare card work in my machine? Please, help.

uname -a

  4.3.0-1-amd64 #1 SMP Debian 4.3.3-2 (2015-12-17) x86_64 GNU/Linux
