Eu instalei recentemente o Ubuntu 12.04.4 LTS com o Xfce 4.10 no meu laptop Asus F5RL AP033C. Quando abro o nm-connection-editor a partir da área de notificações (nele o "Enable Wireless" está em cinza), na aba Wireless não há redes, como no Wicd Network Manager. O WiFi LID no laptop permanece ligado o tempo todo e eu não consigo controlar nem do Wicd nem pressionando Fn + F2 .
Primeiramente, eu procurei no site da Asus por drivers, mas não havia nenhum Linux.
Eu tentei adicionar a /etc/rc.local
da linha:
%código%
Por causa desses tópicos, eu encontrei: 1 , 2 . Uma coisa estranha sobre isso é que eu mudei a linha, eu estava adicionando de echo 1 | tee /sys/devices/platform/asus_laptop/wlan
a asus-laptop
, por causa da pasta já existente.
Esse arquivo asus_laptop
continha wlan
, então eu editei para se tornar 1
e o LED foi desativado. Voltei a ligá-lo, mas ainda não consegui ver a lista de redes disponíveis.
Eu também tentei:
sudo apt-get purge --remove bcmwl-kernel-source
sudo apt-get install linux-firmware-nonfree
sudo modprobe b43
por causa de esse tópico , mas sem nenhum efeito.
Quando pesquisei na rede sobre as características do meu laptop, descobri que minha rede sem fio é 0
.
Integrated 802.11b/g
retorna:
wlan0 Interface doesn't support scanning : Network is down
lo Interface doesn't support scanning.
eth0 Interface doesn't support scanning.
Mas há uma exceção: quando eu inicializo meu laptop pela primeira vez depois de ser desligado, ele retorna:
wlan0 No scan results
lo Interface doesn't support scanning.
eth0 Interface doesn't support scanning.
sudo iwlist scanning

Pode ter algo a ver com o resultado de /var/log/udev
, que muda dependendo se eu desconectar o cabo ethernet ou se eu pressionar Fn + F2 . Expliquei exatamente como em meus comentários sobre a resposta de Olli.
