Problemas para conectar o Ubuntu 9.10 a Internet

Bruno ou Emanuel eu executei o comando que vc falou para mim digitar, mostrou essas mensagem. Tentei fazer a conectar mais não deu certo, só mostrava essa mensagem: rede com fio conectada , porém não entrou na internet. Segue abaixo os comandos e os resultados da execução deles.

No meu notebook HP Pavilion dv6650br ele tem uma chave que liga e desliga o wireless. Percebi que a luz azul no Ubuntu 9.10 não fica acessa mais no Windows fica porque será, e eu não mexo nela, sempre fica na mesma posição.

cat /etc/network/interfaces: apareceu essas mensagem:

Emanuel: Ok, vou digitar esses comandos, já mostro o resultado.

Boa Noite!!

Emanuel e Bruno, conforme vocês mencinarão eu digitei esse comando abaixo e troxe esses resulatdo:

Percebi que esse comando abaixo não mostra nada. Como mostra abaixo:

root@helbert-laptop:/home/helbert# lspci -v | grep -A12 Wireless
root@helbert-laptop:/home/helbert#

Então eu digitei assim e mostrou esse resultado:
