[Wireless] Wireless Blocca tutto su Acer 722

[mauri_maf]

Ciao signori!
Ho dapochi giorni comprato un netbook Acer AO 722. Win 7 più ovviamente Ubuntu 11.04.
Ho però un problema con il wifi.
In win funziona tutto. In Ubuntu i  driver aggiuntivi sono installati.
Quando accendo il wifi dopo un pò si blocca tutto, il puntatore si ferma, non funziona nemmeno un tasto e devo uccidere il pc.
Si blocca tutto in momenti variabili.
Può essere appena accendo il wifi, mentre cerca le reti, quando lo connetto...., cambia sempre ma è ovvio che qualcosa non va.
Ho provato a rimuovere i driver aggiuntivi. Ho fatto ancora peggio...
Disperato...
Grazie mille a chi ha un idea da suggerirmi per aiutarmi...

In che senso 'riprovi da zero' ?  ???
Per quanto riguarda l'errore nella guida segnalalo in Gruppo Documentazione per farlo correggere dagli editori 

[mauri_maf]

Tranquillo, intendo dire che spengo il wifi, riavvio e provo il tutto.

Tranquillo, intendo dire che spengo il wifi, riavvio e provo il tutto.

non importa spengnere il wifi, riavvia direttamente. Al riavvio di solito occorre soltanto selezionare la connessione dal network manager al massimo se non viene selezionata in automatico  ;)

[mauri_maf]

Fantastico! Grazie! Metto risolto.
