Briding two networks for sharing internet connection?

Ok all you netoworking gurus, here's one that's left me stumped!!

I have the following network configuration:

In the living room : cable modem connected to a Linksys WRT54GS wireless router (192.168.1.5). Connected wirelessly to the WRT54GS is a laptop (192.168.1.102).

In the office: A Linksys BEFSR41 wired router (192.168.1.1) with a Linksys WET54G wireless bridge (192.168.1.103). Connected to the BEFSR41 via ethernet cable are a desktop (192.168.1.100) and a laptop (192.168.1.101).

My goal is to access the internet connection in the living room from the desktop and laptop in the office. I can access all configuration utilities of the various routers from the desktop, as well as ping all IP adresses from the deskto, so this tells me the WET54G and WRT54GS are successfully bridging. However, I cannot access the internet from the desktop. Any ideas?

Thanks for any information you can send my way!
