Forum Ubuntu-it

Salve a tutti!!
Ho un portatile (non più nuovissimo) su cui ho voluto istallare ubuntu server 12.04 LTS per farci un server casereccio.
Dunque, installo tutto, nell'installazione ho usato connessione via cavo perchè non mi rilevava il sever DHCP per il wireless, pensando di riuscire a risolverlo una volta finito il tutto... bene sono giorni che sto cercando di risolvere sto cavolo di problema!! La scheda vede la rete (protetta con WPA), cerca di connettersi ma niente da fare, sembra non acquisica l'ip. A volte si connette per qualche secondo e poi giù ancora, in quei pochi secondi sono riuscito pure a navigare!! Ho installato wicd e tolto network manager e wicd resta in attesa dell'ip....
