Wireless problems

[Atariguy]

I'm using an Ashton Digital AirDash USB Stick to connect to this this Belkin router. Normally, this works just fine, but for some reason, on Sunday the connection cut out during the middle of a game of City of Heroes, and has rarely worked for more than a few minutes at a time since (in the rare instances it works). It's gone out for a day or two at a time before, but never this long. Anyone have any idea what's causing this or how to fix it?

have you released it from the usb manager and then rebooted your PC since then?
