adding 2nd wireless router

I have an older hawking 802.11B router with 4 port switch. the WAN
port stopped working so it no longer worked for receiving and sharing
internet out the wireless or ports. it does appear to still function
as a wireless/wired ethernet hub. I now have a new 802.11G/B router
with 4 wired ports as well, and I would like to use the older router as
basiclly a access point for my XBOX and PS2 at opposite end of house
from new router. I would plug CAT5 from consoles into older router and
it shoud send/receive internet connection across wireless to new
router. I am not sure of where to begin with settings on old and new
router. I need to know how to make sure old router acts purely as a hub
uplinking xbox/PS2. any ideas?
