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.

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.

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.
