I am trying to share my iPAQ 3615's WiFi connection to the internet with my laptop running Windows XP SP1 using a BT connection (Belkin USB dongle). (This is the reverse of the usual situation - I want to use my iPAQ's T-Mobile Hotspot subscription for my Laptop as well).

I have paired the two devices, and the laptop seems to think it is connected to the iPAQ, however that is as far as I get. When I check the connection from the laptop side, it states that "LAN or High Speed Internet Enabled", DHCP is used but the IP address is always 0.0.0.0.
