Então eu peguei meu netbook de 5 ou mais anos, e atualizei o Ubuntu para o release 14.04 (a partir de 10.04) e agora ele pode ver a conexão sem fio e diz que ele se conecta a ele, mas não carrega nenhuma página no navegador, nem carrega o site do roteador. Eu posso conectar via ethernet.
Por favor, note que eu sou um linux newb, só sei postar esses comandos no googling desse problema e ver que outras pessoas postaram eles - por favor me avise se há algo mais que eu deveria postar também, e se você pudesse explicar soluções como se eu tivesse 5 anos de idade, provavelmente ajudaria muito!
Soluções que já experimentei:
