Eu recentemente instalei o ubuntu 12.10 no meu lenovo Y570, e tenho um grande problema em conectar-me a algumas redes sem fio. Então, o da minha casa está funcionando bem, assim como o meu hotspot de celular (ambos protegidos com WAP / WAP2 Personal e WPA (TKIP)), mas quando vou para a biblioteca e tento me conectar com inseguros rede lá Network Manager, depois de alguns segundos de tentativas, está me dando informações que eu fiquei offline. Então eu pensei que era problema de segurança, mas quando mudei de hotspot móvel para não-seguro eu me conectei a ele sem nenhum problema. O que eu também descobri é que as redes que não consigo conectar "parecem" diferentes no gerenciador de conexões (tela anexada).

Não consigo me conectar à esquerda (que tem o Security como segundo cartão) à direita, tudo funciona bem (a segurança é a última placa)
Terei todo o gosto em fornecer dados adicionais que serão necessários. Também devo pedir um passo-a-passo preciso, já que sou novato em Linux.
