Connect dsl/router to cable modem

Hi, I used to have internet connection through QWEST. Now I have Internet connection through Mediacom, which is cable internet. I use a modem called RCA DCM425 as of now. I am aware that this modem is not Wi-Fi, and 2WIRE is. After investigating a lot on the Internet I found out that it is possible to use the 2wire along with the cable modem to provide Wi-Fi. I managed to setup the router once and managed to get on 192.168.0.1, but then it is not allowing me anymore. I wondered where I went wrong, I have the cable modem connected to the router, and have the router connected to the computer. I don't know if I have a static or dymanic ip address, how do I figure that out, and when I have tried pinging 192.168.0.1 it says request timed out. I have copied what I got from the command prompt below and have x out the physical address of my computer.

Any help would be greatly appreciated.
I've attached pictures of both modems below.

From what you post it looks like you need to use "12.201.60.1" to access your router configration.

Your ISP should provide the other info if you can't find it on your router.
