Problemas com o driver WIFI do Debian 9 (nova instalação)

Question

Em uma nova instalação do debian 9, estou tendo problemas com a instalação dos drivers broadcom proprietários.

Eu segui este guia exatamente.

mas na etapa final, recebo o erro modprobe: FATAL: Module wl not found in directory /lib/modules/4.9.0-1-amd64

Eu já vi muitos "consertos" para isso, mas nada parece funcionar. A saída para sudo find / -name "modprobe*" é:

/sbin/modprobe
/lib/modprobe.d
/proc/sys/kernel/modprobe
/etc/modprobe.d
/usr/share/man/man5/modprobe.d.5.gz
/usr/share/man/man8/modprobe.8.gz
/usr/share/bash-completion/completions/modprobe

O comando lspci :

03:00.0 Network controller [0280]: Broadcom Limited BCM4360 802.11ac  Wireless Network Adapter [14e4:43a0] (rev 03) 

Subsystem: Broadcom Limited BCM4360 802.11ac Wireless Network Adapter [14e4:0619] 

Kernel modules: bcma 04:00.0 PCI bridge [0604]: ASMedia Technology Inc. ASM1083/1085 PCIe to PCI Bridge [1b21:1080] (rev 03

e /etc/apt/sources.list :

Answer 1

O broadcom-sta-dkms está disponível no debian stretch, você não precisa adicionar jessie repos (não é recomendado).

Como broadcom-sta-dkms é um software non-free , você deve adicionar o componente non-free ao seu sources.list .

Edite seu /etc/apt/sources.list da seguinte forma:

deb http://deb.debian.org/debian stretch main contrib non-free
deb-src http://deb.debian.org/debian stretch main contrib non-free

deb http://deb.debian.org/debian stretch-updates main contrib non-free
deb-src http://deb.debian.org/debian stretch-updates main contrib non-free

deb http://security.debian.org/ stretch/updates main contrib non-free
deb-src http://security.debian.org/ stretch/updates main contrib non-free

Atualize seu sistema

apt-get update && apt-get upgrade && apt-get dist-upgrade

Remova o broadcom-sta-dkms

apt-get remove broadcom-sta-dkms

Siga o guia oficial para instalar o driver do Wi-Fi (postado em sua pergunta)

apt-get install linux-image-$(uname -r|sed 's,[^-]*-[^-]*-,,') linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,') broadcom-sta-dkms
modprobe -r b44 b43 b43legacy ssb brcmsmac bcma
modprobe wl

    

Answer 2

Tente do synaptic para instalar o broadcom-sta-sources em vez do dkms.
