hello , i'm using a usb modem on a windows xp 32 bit pro version and i'm trying to connect to this computer with a windows 7 64 bit pro version. i made myself a personal ad-hoc wireless network. but it doesn't seem to work. the windows xp computer wireless tray icon seems like it's connected but when i go to the windows 7 computer it's seems connected with an error. any help ? thanks in advance , udi
