RISOLTO!
Il problema era che veniva caricato il modulo prism54 che andava in conflitto con ndiswrapper... è bastato fare: Codice:
modprobe -r prism54 modprobe -r ndiswrapper modprobe ndiswrapper Per evitare di ricaricare ogni volta il modulo prism54 al boot bisogna metterlo nel blacklist, editare Codice:
/etc/modprobe.d/blacklist Codice:
blacklist prism54 |
