Question about RCA DCM425 DIGITAL CABLE MODEM (RCADCM425)
I had a home telephone problem so Comcast just replaced my cable modem. Until now, Internet from Comcast worked WONDERFULLY - not a single issue in years of service. As soon as they installed the new RCA modem - two things started happening. First, my Apple Airport Extreme router occasionally reports that there is no connection and then auto-reconnects after about a minute. Second, DNS look ups take 7-10 seconds each time I try to connect to websites. Both problems are driving me nuts and comcast tech support is incapable of troubleshooting because they can see the modem each time I call to complain. Then they go down the path of "well, we don't support routers" and I just want to scream. :-) Could there be a documented problem between an Airport Extreme and the new RCA modem? Maybe some setting somewhere that I can change that would make the two work better together? Or is this simply an RCA modem issue and I should press for another replacement?

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.

SOURCE: rca dcr425 modem, trying to
usually the connection of a router to the modem is made by selecting to get an IP automatically ...and it will do so ..The only issue is to see if the 2 devices not have the same Ip address from factory so that they are not in conflict ..If they have ..just change the one in the router..
The issue is that you didnt managed to make a internet connection directly in the modem either..This is your main concern ..After you make the modem work it will work with the router too cause you do not need much settings if it takes the You will have to enable the wireless so ...and the ports will take IP addresses in order..
Sop ..first see whats wrong with the modem ..If it is a provider preset one ..than remove it from the power plug .,..and plug it back after a while ..and it iwll get back to work ..or call the ISP and see whats wrong ..You will not be able to make it work until you have internet connection in the Wlan port of the router..
here are instructions for connecting a router to a modem ..

I was banging my head for 2 days with about 35 different configurations and finally tried the following and it worked just fine. Also, tried connecting 3 computers and they all connected with "NO" issues. Even connected wireless with "NO" issues. Now I am at 20mb download speed...J compared to AT&T 1.5mb download speed.
This is my DLINK model -> (DIR-601 Wireless N 150 Home Router Wireless router)
1. Reset your Comcast Surfboard Cable Modem by unplugging it for 5 minutes.
2. Then reset your DLINK Router to the manufactures default settings. Then Unplug DLINK Router for 1 minute then plug it back in (Just plug your cat5 cable into port 1 and connect it to your computer) there should not be anything else plugged into the DLINK Router at the time you make the changes. Just 1 computer can be connected.
3. Went into the DLINK configuration 192.168.0.1 and changed the PPPOE setting that I was using for my AT&T Modem to Dynamic IP (DHCP). Once you make the changes save them and then unplug your DLINK Router it's off.
4. Turn on Comcast Surfboard Cable Modem and wait until all lights are on. Now plug in a cat5 cable from the Surfboard Comcast modem (NOT A CROSSOVER CABLE LIKE THE CD INDICATES) to the INTERNET port of your DLINK Router. Now turn on your DLINK router.
5. Then turn on your computers or restart them and it will pick up IP Addresses from your DLINK Router
