Erro ao tentar acessar rede Wireless.

[Rodrigo Tavares <digolinopage@yahoo.com.br>]

Pessoal,

Consegui levantar minha placa de rede Wireless. 
Tanto que usando o utilitário do gnome configurei a
placa para pegar configurações do DHCP da rede (usando
chave do WEP).

#/etc/network/interfaces
iface wlan0 inet dhcp
wireless-essid INFOR
wireless-key on
wireless-rate auto
auto wlan0 

# comando iwconfig

debian:~# iwconfig 
lo        no wireless extensions.

eth0      no wireless extensions.
