Platform Win xp sp2, mbo gigabyte 945gzm-s2
In my network connections I had Dial-up connection
Local area connection(cable unplugged) and 1394 net adapter icon. When I installed wireless usb connection, 1394 net adapter disappeared after few days. After that I couldn't find it or install it in every way imaginable. I even formated hdd and installed same version of windows and nothing. I didn't change anything in bios in meantime, and I didn't install wirelles usb connection.
HELP NEEDED URGENT!
