Just you to your sister, and nobody else? All the time? Complain to Earthlink. They will probably give you an excuse, like "that happens from time to time". Real answer: cheap internet connections and software that drops out.

We have our own VoIP box that cost $50 (ObiTalk), pay $60 a year to PhonePower (one of many), and have had rock steady connections. We get free Canada calls, and a half hour of free overseas every month. If you pay more than $5 a month rethink your provider.

SOURCE: 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.

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

SOURCE: How can I install a wireless router to RCA cable

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.

SOURCE: Hi, I want to set

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.

Since Daylight Savings started on Nov 3, the clocks on all my phones jumped AHEAD one hour instead of back. I have tried everything I can think of including resetting my modem( I have Time Warner Cabl


You're time warner cable upstream provider is in another time zone. Are you close to a time zone border? Example of this is Mississippi and Georgia - you can live in Mississippi but get your internet connected (via network) to Georgia. That would produce Georgia time on Mississippi equipment.

I have the DCM425 RCA Modem and I'd like to use it with another internet provider but I don't know how to get it connected. Can you help?


Hi.

You should have no problem using the modem with another internet provider as the modem is a cable modem and not a ADSL modem.
Make sure that your new ISP (internet service provider) is supplied by a cable company and not one that comes through the telephone line as the modem will not work if that is the case.
Once you have cable installed its as simple as connecting all the leads like the coaxial lead and the Ethernet lead. turn it on and you should be good to go after about 2 minutes.

Click on the link below for an on-line PDF operators manual for the RCA modem which will tell you exactly how to install the modem.

How can I connect two ethernet cables to this modem?


If your Internet Cable Provider allows it,you will need :

1. Crossover-wired, or "null," category 5 Ethernet cable for the cable modem to be connected.
2. 10BaseT or 100BaseT Hub or Switch.
3. Straight through, or standard, category 5 Ethernet cable (one for each computer to be connected).

Be sure to check with your Internet Provider first.

Can i hook up 2 computers to the rca dcm425 without a wireless router


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.

I lost the disk for the RCA DCM425 digital cable modem the cable company gave me. how can i get the modem to work on my new computer?


Hello Friend,
If you didn't change anything in modem side, that means the modem is still connected to internet. in this case you can connect the modem to your computer via the Ethernet cable. with this cable you will not need to install anything on your computer, just plug the Ethernet cable to the RJ45 port and start browsing internet.
The only case when you will need the drivers is when you want to connect the modem to your PC via USB cable.
Here is a link where you can find everything about your modem: quick guide, user manual, usb drivers ...
Best Regards,

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.
