Eu apenas dual-booted windows 7 com Debian 7, durante a instalação ele disse que o firmware wifi estava faltando então eu instalei sem uma conexão com a internet, após a instalação eu tenho o meu cabo LAN para instalar vários programas mas agora estou tendo problemas ao configurar a conexão wifi, na partição do windows wifi funciona bem.
Então, a primeira coisa que fiz foi instalar o módulo para minha placa wifi, que é:
Intel Centrino Advanced-N 6205
Eu fiz isso instalando o iwlwifi no apt-get.
Depois disso, eu reconheci o meu cartão porque eu podia procurar pela rede:
root@debian:/home/user# iwlist wlan0 scan

Eu então instalei o iw para tentar se conectar à rede:
root@debian:/home/user# iw dev wlan0 link

Ele diz que eu estou conectado ao roteador, mas ainda não tenho acesso à Internet.
Mais alguns resultados:
