Wifi si blocca di continuo

[pokinmba]

Ciao ho un portatile con ubuntu 12.04 lts (è un fujitsu siemens amilo si2636) con ubuntu e windows, mentre con windows non ci sono problemi, con ubuntu il wireless salta di continuo, cioè al posto di aprire una pagina carica all'infinito senza risultato, quindi sono costretto a toccare il tastino laterale che spegne e accende il bluetooth su 0 e poi di nuovo su 1 per far riconnettere in automatico alla mia rete e farlo funzionare di nuovo fino al prossimo "blocco", qualcuno può aiutarmi? grazie, ciao.
