I tried the kernel and the nohwcrypt solutions but didn't work for me, so i've downloaded and installed the madwifi drivers (sorry i can't pont the website, but there's a lot of how-to's about the procedure). It was my last choice since i don't like to mess with the modules and blacklisted modules... but maybe somebody will need this workarround. Thank you all for your comments anyway. :)
