Set up netgear WGT624 as a bridge

I was wondering if it was possible to set up the WGT624 as a bridge
(or wireless access point, I am a little confused with the
terminology) to my existing network. I just moved in to a new place
and the guys I live with already had a network setup with router and
dhcp and all that, and I am bringing the wgt624 with me. I would like
to be included in their network, but as it is now, I can't get to any
of the other machines on the existing network. I can get to the
internet, but its like my local network doesn't exist. I can't see
the other computers, and the other computers can't see me.
