Интерфейс № wlan0: Ubuntu 16.04

Я установил b43-fwcutter и firmware-b43-installer на моей человечности 16.04 (HP Pavilion G6 - 2149tx) ноутбук.

sudo apt-get remove --purge bcmwl-kernel-source 
sudo apt-get update
sudo apt-get install b43-fwcutter firmware-b43-installer

Но я не мог создать интерфейс wlan0 на своем ноутбуке.

ifconfig wlan0 up
wlan0: ERROR while getting interface flags: No such device

Мои конфигурации следующим образом:

iwconfig
