WRT54G Can't Connect with Motorola SB5120 Cable Modem

Unfortunately I had to swap out my old cable modem from Comcast with their latest SB5120 modem. Now my router cannot connect with the modem and get an IP address. This occurrence has happened with 2 different routers( the other is a Belkin which worked perfectly with the previous cable modem).
 
The cable modem works fine hooked up to one PC. Comcast says that is as far they support. No help with a router.
 
I can web browse to the routers firmware no problem. I even tried setting up the router with a static IP no luck.
 
I've gone through all the power down cycle suggestions etc. no luck.
 
HELP!!!!

Try to change the LAN IP of the router to 10.10.10.1
