If you are just setting up your connection your service provider may need to establish your IP address and/or Subnet Mask.

Also the signal or connection to your modem is not available due to your cable line not having a direct path back to the hookup at the house or a loose connection.

Hope that helps get things right. If you need more help just let me know.

The first four lights should be on. Internet / PC Link / Cable Link / Cable Activity. The "PC Link" and "Cable Activity" lights will blink. The "Internet" and "Cable Link" lights should be solid green. That's 4 lights on when all is good. I hope that this will help.

Any questions you may still have I will be glad to answer.

> any change this is modem-related.

Yes. Ask the technician to confirm that your modem is "grounded" correctly. Get the technician to bring a different modem, and experiment with that modem.

RCA DCM425 digital cable modems only have one Ethernet cable located in the back of the device. In order to have two computers connected at the same time you will need to have router. The router will connect to the Ethernet port on the back of the RCA modem and then you can have up to 4 computers connected directly to the router using Ethernet cables. If any of your computers are wifi compatible they will also be able to get online by using the wifi from the router.

Try updating the firmware of the modem.
If that doesnt help try getting a new one.

Of course the first thing to do is to check the connection of your cable all the way to the wall. Did you disconnect anything?
It is usually best to unplug the cable modem from anything connected to it and to check after you disconnect if from the power outlet and the cable. First connect the cable back and then the power and check what is going on there. If you are connected to Cable TV then of course check your TV set if you are getting anything.

you can try to log into the modem itself: For a RCA cable modem, you may need to navigate to to view the diagnostics.

I would also love to know the answer to this I need to open my port to on the modem so I can use the network camera.

RCA DCM425... | Answered on Sep 02, 2010

I would first make sure there is power to the outlet that your modem is connected to. If you already have something else on that outlet and it works, move on. Hook a light into the outlet to check - you may have tripped a breaker or blew a fuse to this outlet. If the outlet is OK, the surge during the outage may have destroyed the modem. You can take it to a repair shop or buy a new one. Any warranty will not cover the item. I suggest getting a surge protected outlet for all computer devices. Good ones are not cheap, but they come with insurance to pay for your devices should something happen.

Contact your Internet Service Provider.
If they want to keep you as a customer of theirs, they will trouble-shoot their modem, remotely.
