Can you connect a router to a dcm425 router - RCA DCM425 DIGITAL CABLE MODEM (RCADCM425)

SOURCE: How do I connect this router?

You will need at least two ethernet cables like the one that is currently connecting yur PC to your Comcast Modem. Use one cable to connect between your pc and any of the ports labled 1, 2, 3, or 4 on the router. Another ethernet cable should be connected between the modem and the port labeled WAN on the router. Then (if you havent already), turn off the power to all three, the modem, the router, and the pc. then, turn on the power to just the modem and wait until the lights on the front of it stablize (usually about 60 to 120 seconds). Then turn on the router and wait another 60 seconds. Finally, boot up the computer. You should be able to connect to the internet. the next step will be to set up the wireless part of the router.

First try connection the Yellow ethernet cable from the rca modem to your computer's network connection. If you get a connection this way, then your modem will work with a ethernet cable. If not, then call Comcast for help. The modem ethernet out to computer port must be connected to the wan line of the router. Then you can connect an ethernet cable from your computer network connection to one of the 4 ports of the router. For wireless connections you must set up the router and wireless adaptor with the same settings to connect. Follow the routers directions.
Good Luck

My RCA DCM425C from Comcast had the same problem when I came home Saturday, 11/14/09 (coincidentally the same day you posted). Had been working fine - cable TV still works fine including On Demand, etc. The Internet light was blinking. Occasionally I'd see it try to work from one light to three or four, but it always came back to one. Called Comcast, they said their side showed "no signal". Sent out a tech today. He replaced the cable modem, reprovisioned it (I guess if I had a backup ready I could have done the provisioning over the phone maybe?)), everything's great. Lasted about a year and a half. When I logged in via http://192.168.100.1, it said it was still in Step 1 of 5 ("Tuning"), and the logs showed a whole bunch of errors on Saturday that stopped after that. Diagnostics would always freeze the built-in web server and require reboot.

The trick about all this is that the software does not configure the computer, but the modem.
So once it has been configured through a computer then plugged to a router, any computer plugged to the said router will have access to the Internet.

The whole process of installing/configuring will happen if you replace the old modem and/or plug a new computer directly to the modem.

1) Make sure the cable is plugged into the Internet port (or whatever the appropriate port is, since you didn't specify exactly which router).

2) At your router's configuration page, make sure DHCP (Automatic) is selected.

3) After connecting to the router, if it still does not work, open up the command window by going to the search box in the Start Menu or click Run... and type "cmd".

4) Type "ipconfig /release". Wait until this is finished.

5) Type "ipconfig /renew". Wait until this is finished.
This should have given you an IP Address.

6) Try to connect to a website.
