How to configure Belkin Wireless G Router with a Netcomm NB3 modem

[JTC]

Hi,
I have a friend who has just signed up for ADSL and it came
with a Netcomm NB3 modem. He wants to connect a couple of computers wirelessly with a Belkin wireless G Router.
Does anyone know how to configure these two to work together.
The router doesn't seem to allow/detect the modem.

Thx.

He might need to add the modem to the trusted zone on the router.
