DSL modem + wireless Router

I have a Linksys BEFW11S4 wireless router and a Sprint 642R DSL
modem. I cannot for the life of me get these two working together. I
believe the DSL modem is also a router since I have had it hooked up
to a regular hub with 4 computers.

Okay, so with the wireless router I set that up according to the
instructions, I check the "status" page and can see where the wireless
router has obtained an IP address and DNS addressed from the DSL
modem. I only had one computer plugged into the router and under the
"network" status, I can see where it has issued an IP address to the
computer.

One thing about the IPs...the number issued to the wireless router
from the modem is a local 192.168.1.x address (probably because the
DSL modem is also a router). I've set the Wireless Router to issue
IPs out of 192.168.0.x to the computers.

So everything looks like it should be working. But the computer
cannot access the internet. Any one have any clues what could be
wrong?

Thanks in advance.
