Acabei de instalar o Ubuntu 12.04 juntamente com o Windows 7 no mesmo laptop - o Dell Vostro 3560.
Agora, no Windows 7, posso acessar diferentes redes wi-fi. No entanto, quando estou logando na seção Ubuntu (depois de reiniciar meu laptop) - uma mensagem de erro aparece:
Disconnected - you are now offline
Quando dou uma olhada no meu menu de rede (na barra superior da tela), vejo que nenhuma rede foi encontrada (e eu tenho algumas delas na área).
Eu tentei olhar em volta, mas realmente não consegui encontrar uma solução prática concreta para esse problema específico, apreciaria qualquer solução de alguém que tivesse esse problema e resolvesse o problema.

A - sugestão da web-e de procurar drivers adicionais não mostrou nada
@ WEB-E, você sugeriu que eu fizesse o seguinte:
1.check para drivers adicionais - não mostrou nenhum resultado relevante
2. execute o comando lspci -vvv no terminal. o resultado relevante (comunicação - ethernet, etc .:
