wireless network(s).. complications

I bought myself an airport extreme today and after a few minutes I've managed to get my imac c2d and mbp c2d online

I attached my old USR 5461 router to it with an ethernet cable so that I could turn the airport in a real 5Hz N airport, and let my older G-systems (imac g5, PB g4 and win XP) use the USR for internet at a lower speed

So far so good..

in a nutshell:


BUT then.. printing

the red arrows are printerconnections over the wireless network, I can't setup.
the macs don't find them neither by using bonjour, appletalk or whatever..


and..
the purple arrows are ARD connections I'd like to use (I used them before I switched to the A.P.Extr(n).. and the macs don't find eachother either..

any help on these 2 problempoints?

just a basic website or so which gives a generic setup guide will do.. I just need *something* to start with, I'll figure out the rest.. I hope..


Thanks!

 

aha!

that should be the trick

I chose the Wan instead of the Lan port..
and yes.. I've got 2 DHCP's at the moment..

should be solved in a minute, but that's for tomorrow.. it's too late (or early..) to try it now.

thanks!
