WIFI na inicialização, mas desconecte imediatamente

Question

Eu tenho um asus N550JV rodando o Ubuntu 14.10.

Substitui o Unity pelo i3 e estou com problemas de rede desde então.

Neste momento, meu Wi-Fi é conectado assim que o i3 é carregado, mas ele é desconectado após 1 segundo. A Ethernet permanece nesse meio tempo.

Alguns detalhes:

@dev-Laptop:~$ sudo rfkill list all
0: asus-wlan: Wireless LAN
    Soft blocked: yes
    Hard blocked: no
1: asus-bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: no
2: phy0: Wireless LAN
    Soft blocked: yes
    Hard blocked: yes
3: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no
@dev-Laptop:~$ sudo cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

auto wlan0
iface wlan0 inet dhcp
        wpa-ssid ssid
        wpa-psk password

Se eu adicionar rfkill unblock all a /etc/rc.local , ele não será inicializado com nenhuma rede, embora rfkill list all mostre que tudo está desbloqueado.

Na configuração acima:

@dev-Laptop:~$ sudo ifup wlan0 -v

Alguma idéia de onde tirá-lo daqui? Eu pesquisei por algum tempo e tenho gerente para obter uma conexão trabalhando através de wpa_cli, mas isso não persiste.

O wifi é protegido com WPA / PSK2.

Tenho certeza de que assim que a inicialização estiver completa e o módulo auxiliar asus_nb_wmi for carregado, o OFF será o wireless; por favor note:

% bl0ck_qu0te%

Vamos tentar um parâmetro de driver. Por favor, abra um terminal e faça:

sudo -i
echo "options asus_nb_wmi wapf=1"  >  /etc/modprobe.d/asus_nb_wmi.conf
modprobe -r asus_nb_wmi
modprobe asus_nb_wmi
exit

Pode ser necessário reiniciar. Alguma melhoria? Se não, repita a seqüência acima, mas use 4 ao invés de 1:

sudo -i
echo "options asus_nb_wmi wapf=4"  >  /etc/modprobe.d/asus_nb_wmi.conf
modprobe -r asus_nb_wmi
modprobe asus_nb_wmi
exit
