Question about RCA DCM425 DIGITAL CABLE MODEM (RCADCM425)

Open Question

I have an RCA dcm425 modem thru Time Warner. It's worked fine for a year, but now I'm getting solid lights for everything but Internet. Resetting doesn't help and I've also tried plugging into different outlets. There's no Internet on/off button, so thinking it's an old model. Does the modem need to be replaced?

SOURCE: RCA DCM425 modem ethernet connection won't work

The setting for the Computer 1, use the network connection wizard to automatically configure the modem to work as a server station. Next, set the IP number manually and the DNS at automatic or is given by your ISP. Now the Computer 2 (workstation) should be connected to a Hub/Switch. The same, go to network connection wizard and select the appropriate connection setting, there are view samples for the connection types so explore them. After the setup, try loading your internet browser.... When done, it should work fine. Keep me posted for any problems.

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

How can I install a wireless router to RCA cable modem DCM425 installed by Time Warner?


From the back of your modem, follow the ethernet cable to your PC (in). Mark or remember this location. Remove this cable from the PC and insert it into the INTERNET port on your router. Then take another ethernet cable (usually supplied) and insert one end into the ETHERNET port of the router, and the other end into your PC (where you originally removed it. Remember to check all connections and plug in the modem. You should now be good to go! If your PC has an installation Wizard, you can browse thru it as well.

Shuts off...restarts, then runs for a few mins


If the modem is 10 years old then its time to replace it even if it was working fine if not very good to be abreast with the latest technology. The ISP must have tested the lines which must be fine because they keep on upgrading so you need to replace the modem to a latest model.

The internet light is flashing on the rca dcm425 i reset it and the router and still cannot connect but the cable is working and the light just flashes


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.

Internet Light keeps blinking - all others are out - No internet


HI,

Blinking green internet light is normal BUT you must check if theres any dsl outage in your area..You can contact your ISP for that.

But then maybe you can try this:

Turn your PC off > then you modem or router.. after 60 secs turn your modem or router ON first then your PC and check if you can go online.

If you called your internet service provider {ISP} and no reported outage let me know and we'l solution for that.

Keep me posted.

Cheers.

Loss of internet connection


Sounds like a switch before the signal gets to your house. Modems usually don't go out intermittently unless they are overheating. Is the modem in a ventilated area where it can get some air? An alternate is to borrow a modem from a friend to test it. Usually one of your niehbors will have the same service and the same modem. I had my surfboard (from comcast) for 5 years and it was solid as a rock, the spotty services was always at the Comcast switches (at the street or the nearest hub.

Hope this helps

Do I need to open ports?


There are no ports to open on the DCM425, as it's a cable modem, not a firewall. Earthlink/Time Warner will likely not be truthful when it comes to blocking ports on their end. Would it be possible to change the port that your PS2 is using?

Same goes for the bittorrent question, only I'd switch to uTorrent and different ports as well.
