Im desperate for help please.

I have an IPAQ 2210 and have just bought a Trust BT120 USB bluetooth dongle.

My full network consits of 1PC with the internet via a USB cable modem using internet connection sharing i then have a laptop able to surf.
I now also have the usb dongle so after following all the instructions i can get a network connection and an internet connection via bluetooth but when ever i type a URL i get "the page you are looking for cannot be found" if i use MSN i get a message saying you are not connected to the internet.

i can surf using the pda cradle but not via the internet explorer in Pocket PC 2003.

does anyone have any ideas pls ?
