ho installato Ubuntu 9.10 32bit insieme a windows 7 64bit,col mio adattatore wifi linksys WUSB54GS,network manager rileva reti protette ma non quelle aperte,con windows invece non aveva problemi,allora ho disinstatallato network manager e messo wicd col quale non rilevo piu neanche le reti protette.
qui alcune cose dal termnale:
