Setting up a Linksys router to expand the network

Hi

I have a PC which has a wireless dongle in it
I have a Linksys WRT54G which I want to attach a network printer to
(jet direct card)
I also have a Linksys WAG54G which is downstairs next to the phone line
for the broadband connection.
The signal from the PC to the WAG is quite unpredictable ad so I would
like to use the WRT to access the network (its in the same room as the
PC) and for the WRT to then talk to the WAG.

I am trying to get the WRT and the WAG to talk to eachother but am not
having much success at the moment.

I have set the WAG up as the DHCP server and the WRT to a static IP.
The dongle also has a static IP.
Both routers have the same network name and are on the same channel
(11).

Is there any othe information I need to give you please (never done
this before!!!).

Thanks
