Tethering connection Times out.

[Beach]

Hi, im using internet sharing on my mogul. DCD 3.0.0 w/ latest radio rom. It connects just fine and works for about 5 minutes or so. But then it just sort of times out. On the phone it still says connected but the internet connection is completely dead. When i try to click on the network connection nothing happens until i hit the disconnect on the phone. Was wondering if anyone had a solution to this problem or if its sprint catching on. I'm using it via usb connection on my windows xp 32bit desktop. Thanks
