WiFi não funciona no Debian Jessie

Question

Tenho problemas com o meu controlador WiFi no meu computador portátil Acer E5 575G.
Eu tentei instalar drivers manualmente e eu tentei mesmo apt install firmware-realtek e apt install firmware-atheros
Eu até tentei instalar drivers manualmente do git mas sem sorte.

Informações úteis:

Só para esclarecer as coisas, meu adaptador ethernet funciona, mas meu WiFi não funciona. Outra coisa, meu WiFi sempre funcionou de maneira simples no Fedora e no Ubuntu.

Alguma ideia de como corrigir isso no Debian?

Obrigado.

O driver ath10k não está disponível no debian jessie, você deve obtê-lo a partir de backports.

Adicione a seguinte linha ao seu /etc/apt/sources.list :

deb http://httpredir.debian.org/debian jessie-backports main contrib non-free

Pesquise e instale um novo kernel a partir dos backports:

apt-cache search linux-image
apt-get install linux-image-xxx
apt-get install linux-headers-xxx

Reinicialize e instale os firmware-atheros dos backports:

apt-get update
apt-get -t jessie-backports install firmware-atheros
modprobe ath10k
