Cisco uBR924 Internet configuration

[Poloboy]

Hi everyone,
I just bought a cisco uBR924 for use with cable modem at home. It's a cable modem with built in router. But I don't want to use the routing feature. I have a wireless router I like to use. I'm having problem connecting to my ISP. I'm unable to receive an IP Address dynamically. I had provided them the MAC Address of the cable modem.
Here is the script that default with the cisco uBR924, which setup as a bridge. Please help.

Thankyou everyone
