J'ai installé b43-fwcutter & firmware-b43-installer sur mon ordinateur portable Ubuntu 16.04 (HP Pavilion G6 - 2149tx).
Sudo apt-get remove --purge bcmwl-kernel-source
Sudo apt-get update
Sudo apt-get install b43-fwcutter firmware-b43-installer
Mais je n'ai pas pu créer d'interface wlan0 sur mon ordinateur portable.
ifconfig wlan0 up

Je dois installer wlan0 sur mon ordinateur portable. Merci.
Votre interface sans fil est wlp7s0b1
pas wlan0
. Oh mec, tu devrais accorder plus d'attention aux tutoriels et aux recherches avant de poser une question ici.
