Estou usando o ubuntu 15.04 vivid, estou conectado ao wifi, mas quando abro o Firefox, ele diz "Servidor não encontrado", abro o Software Updater e diz que Falha ao baixar, basicamente sem acesso à internet. Mas eu já usei o ubuntu 14 antes e poderia usar o wifi normalmente sem nenhum erro. Além disso, meu Windows e meus telefones também funcionam sem erros. Eu já reinstalei várias vezes e tenho o mesmo problema.
Aqui estão algumas informações sobre minha situação:
Meu dispositivo wifi é: Huawei HG8045A
