Placa USB Wireless do notebook A530

[alan_ribeiro]

ola todos.
Estou tentando configurar minha placa de rede USB do Notebook A530.
Apesar do Led estar sempre aceso, o que indica que alguma coisa deve estar funcionando, não consigo conectar, nem configurar o endereço da rede via pump.
Um ifconfig wlan0
retorna:

wlan0      Encapsulamento do Link: Ethernet  Endereço de HW 00:00:00:00:00:00
         BROADCAST MULTICAST  MTU:1500  Métrica:1
         RX packets:0 errors:0 dropped:0 overruns:0 frame:0
         TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
         colisões:0 txqueuelen:1000
         RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

quando tento: pump -i wlan0
retorna:
Operation failed.

Listando os dispositivos usb com: lsusb
retorna:
Bus 004 Device 002: ID 124a:168b AirVast
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 002: ID 0ea0:2168 Ours Technology, Inc. Transcend JetFlash 2.0 / Astone USB Drive

Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

Alguem poderia indicar qual o problema ? Porque não consigo usar o pump para pegar um endereço??
Agradeço desde já sua ajuda.

O pump é para configurar a rede obtendo o endereço IP, Gateway, etc, mas a parte "wireless" tem que estar configurada e funcionando antes que vc possa usatr o pump.

Essa parte wireless corresponde a essid, ap, canal, criptografia, etc.
Tem certeza que ela está funcionando?
Posta o resultado do comando iwconfig para ver se está tudo ok.

O resultado do iwconfig é:
lo        no wireless extensions.
eth0      no wireless extensions.
wlan0     no wireless extensions.
sit0      no wireless extensions.

Pesquisando na Internet encontrei uma lista de comandos. Criei um script bash.

#!/bin/sh
sudo wlanctl-ng wlan0 lnxreq_ifstate ifstate=enable
sudo wlanctl-ng wlan0 lnxreq_autojoin ssid="alan_michel" authtype=opensystem
sudo iwconfig
sudo dhclient wlan0

quando executo o script pela primeira vez acontece o seguinte:

message=lnxreq_ifstate
 ifstate=enable
 resultcode=implementation_failure
wlanctl-ng: No such device
lo        no wireless extensions.

eth0      no wireless extensions.

wlan0     no wireless extensions.

sit0      no wireless extensions.

O fato é que não sei bem o  que estou fazendo. Segui o script e funcionou.
Gostaria de entender e deixar a rede funcionando assim que der o boot.
Você pode me ajudar ?
