SOURCE: RCA DCM425 modem ethernet connection won't work

In short, you have to either

  1. renew your ip on Computer 1, or
  2. hard-reboot your cable modem and then reboot or renew your ip on Computer 1.
Details below.

The modem is communicating with the servers at your ISP (Internet Service Provider) to give your computers an IP address. The ISP may have your modem set up to be issued only one IP address. Thus using both USB and Ethernet could be restricted by your ISP.

The IP address is most likely a dynamic IP that expires after a few days or weeks, unless you bought a business account that has a static IP (which is used for hosting permanent websites).

When a computer is not communicating with a Cable Modem or you shift between the connections on the modem, it may be necessary to re-establish configurations. The following can be steps to reset all components to re-establish configurations:
  1. Do a hard-reset on the modem. On the back of the modem is a reset pinhole. If you press the button quickly, this can soft-reset the modem, just restarting the modem. If you press the button and hold it for more than 10 seconds, this can hard-reset the modem, thus resetting and re-establishing configuration with the ISP servers.
  2. Restart the computer or at the command prompt (Start | Run | Cmd | Enter) issue two commands ... "ipconfig /release" and then "ipconfig /renew". This will release your IP and request a new one from your ISP.
These steps are required when adjustments occur especially when shifting between connections on the back of the modem.

SOURCE: trouble connecting netgear wireless router to rca modem DCM425

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

I have a dcm425 and when online gamming the router restarts itself every 10 minutes...

That's obviously a problem with your unnamed router, and not the dcm425.
Try looking for and flash upgrading (or downgrading) your router.
I had a Linksys router that I always kept up to date with the latest firmware, and one day it started doing the exact same thing we're talking about here. I had to downgrade the router to a previous version to fix the issue. Newer isn't always better!
