wifi not working with 4.4 fw for touch 622

Hi there
my pb 622, with the latest firmare 4.4, ends the wifi connection with a "disconnected by the by user" message each time I try to connect, living me disconnected

anyone experimented such behaviour and, more interesting, has got a solution?

edit:

sorry, forgot to check russian site, they're working on that
