Wireless with Windows ME problems

My belkin F5D7050 wireless adapter connects to the wireless network for
about
5 minutes, and works fine. After 5 minutes or so, it stops functioning,
and will not start up again unless the whole system is rebooted, and
then again it will work for about 5 minutes and stop. After it stops,
when i go to Windows systems screen and check the device manager, it
does not appear at all; whereas when it is working it appears as a
belkin wireless adapter.
why does this happen, and how can i stop it?
I don't have anything else connected to the usb ports except the
adapter.
thanks.
