Wireless Ubuntu

Olá pessoal

Eu tenho um HD e um SSD

Instalei o Ubuntu no SSD e estava tudo mil maravilhas

Tive que formatar o SSD pois é muito pequeno e instalei o Ubuntu no HD...

Agora estou com problemas no meu Wireless...

Ele não conecta no wifi da faculdade, não tem senha, e sempre funcionou tranquilo

Quando eu logo no Windows ele fica 5 pontos, e nas máquinas dos meus colegas de classe também no linux deles funciona os 5 pontinhos do wifi...

Alguém pode me auxiliar para resolver esse problema??

-qual é a sua wifi?
-qual a saida do comando " lspci " ?
