Ubuntu 10.10 - Wireless não funciona!

[sabrinadfs]

Pessoal,

Sou novata e instalei o Ubuntu 10.10, mas a wireless não funciona, nem liga a luz do dispositivo wireless...

Executei alguns comandos indicados pela comunidade, mas não sei resolver... de qualquer forma, resultado foi:

Olá juliana,

Instale o pacote "b43-fwcutter", depois execute novamente os comandos de teste, pra ver se a internet melhorou.
