All the needed codes should be on the back or bottom of the modem. Since it doesn't have a wireless router included, there's no WEP code.

If you aren't referring to the DCM425 modem, look in the manual for the ip address or http entry to talk to the router portion of the modem.

The RCA DCM425 is a cable modem. You need an Ethernet router to connect two devices to the wide area network provided by the modem. A router assigns I.P. (internet protocol) addresses. Your Dynex Ethernet hub is a switch which will enable you to share files between computers. It doesn't support directing traffic to and from the internet.

I wish that I had better news for you. You can get a router from many sources.

Who is your provider? The DCM425 is an OLD modem, its on the older DOCSIS standard and its only rated for something like 35-40mbps, i don't remember the exact number from the specs as we haven't been dealing with them here for about 8 years now. Upgrade the modem, go with something like the Surfboard SB6183 or SB6141, this depends on who your provider is also of course. If your current modem is a rental from your provider ask them for a new one, but if you want to get rid of the monthly rental fee get a new modem yourself. But i would find out what modem models are supported by your provider.

All cables may be secured but the internet signal is not enough to keep the modem latched. When it drops too low, the modem lets go and tries to acquire it again. You need to check all the connections and you may have a screen on the modem setup that shows you the signal strength. Keep in mind that any connection your signal travels through causes a loss of signal and the SPLITTER connections are big loss of signal devices. If you lose 3dB it is half the signal

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.

Pull the power line from the modem, for atleast 15 seconds, plug it back in. (Additionally, try pulling all wires from the back and replacing them and ensure the jack is finger tight) If it doesn't return to its normal operation then most likely it suffered from a surge and fried a circuit or two inside of it, at that point take it back into your provider and get it replaced, most providers trade modems out for free.

Yes. My "home" network starts with the cable-modem, with an Ethernet cable between the cable-modem and the "uplink" port on my wireless router, and up to 4 computers connected to the 'LAN' ports on the router, plus support for my wireless devices (laptop, iPhone, tablet).

Reset the modem by removing the power cable from the back of the modem for a full 30 seconds and plugging it back in.


This is sometimes referred to as "power cycling" the modem, and is a good way of clearing network timeouts and other problems that can appear on modems that have been running continuously for some time.


Reset the modem by unplugging the power cord from the electrical outlet or surge protector into which it is plugged.


This is a good alternative to removing the power cord from the back of the modem if it is difficult to get to the modem because of its physical location. Count the full 30 seconds and plug the modem back in to complete the reset.


Reset the modem by pressing the reset button the back of the modem.

The button itself is recessed into a hole to prevent accidental resetting, so you will need a pen or some similar thin utensil that can fit inside the hole.


Press the pen into the hole until you feel the button depress and then let go.

This is sometimes called a "hard reset" or "hard reboot," as this will restore the modem to its factory default settings


Hope this helps

Contact the cable company or ISP and tell them the DNS server setting is expiring too often on your automatic modem configuration settings provided by the Internet service provider..
