I kept an old Linksys WRT54G router around in case I wanted the wifi stuff on the G4/G5 mac or even older gaming consoles like the Wii. Keeping the old legacy stuff off the newer router and having them connect on up to the linksys instead.
If you can source an older Wireless G router, you can specify a different IP address to the old router (whether you put it in a different subnet like 192.168.2.1 or piggyback on the same network with a 192.168.1.x where x is your number besides 1 and not an IP given to a different device on your existing network) If you go with a different subnet, you can plug a cat 5 into the "internet" side of the old router onto your main router...
If you all want to co-exist on the same network, just be sure to assign a different IP to the old router following the same IP subnet such as 192.168.1.x where x is your ip of choice, and then Shutting off DHCP of the old router. Plug an ethernet to one of the switchports and NOT the internet one.
Flashing DD-WRT or Tomato to your old router will let you disable the WAN and use it as a standard port to the LAN.
Just a suggestion as a possibility that new routers don't like playing with old wireless technology.
