How would you hook up a wireless router to your system when you already have 2 router in place (1) for telephone (2) road runner ----this so I can use my new laptop in another room

I actually have a simialr setup. When I initially set it up, I daisy chained the wireless router to my wired router and then disabled DHCP on the wireless. Later, for reasons I don't recall I switched them, using the wireless as my main router enabling DHCP and disabliong DHCP on the wired router, effectively turning it into a switch.

Since the VoIP box should be plugged into a router port, it doesn't enter into the picture.
