I'm guessing you're trying to connect through wireless.
Try connecting physically with a cable, then you can access the controls of the router and set the network key to whatever you want.

Open INTERNET EXPLORER and. (In the URL address field), enter the IP address for your wireless router ( the DEFAULT GATEWAY. This information should be contained in your router's manual. If you cannot find it, enter "198.168.1.1" as the address. This is usually the default IP address for most routers.do not type "www" just the number
Enter the username and password for your router. This should also be supplied in the router's manual.

This site lists the default login information for most wireless routers you can try "ADMIN" for user name and "PASSWORD" for passsword.

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.

I have the RCA DCM425C cable modem and also Vonage phone service. So my modem ethernet connects to my Vonage internet. I would like to go wireless in my house. How would I do this?


You would connect from the output of the Vonage modem to the wireless router and then from the wireless router you can connect Ethernet to your desktop if you have one and then anything else can run off of the wireless.

or

get a wireless router / cable modem combo provided by companies such as netgear then you would connect the Vonage to the router through one of the available Ethernet ports and any other Ethernet connections to the router as well and anything else wireless would work wireless.

Can't connect to internet through Netgear WRG into Speedtouch DSL


Here are some troubleshooting steps that I suggest you try:

1. Check physical connections.

a. Connect the modem to the Internet port of the router. The Internet “i” LED on the front of the router should light up.
b. Connect the computer to one of the four LAN ports (i.e port 1, 2, 3 or 4) on the back of the router. The corresponding port light where you connected the computer should be lit up.

2. Access the router's web-based utility.

a. Please open any web browser like Internet Explorer or Netscape Navigator.
b. Connect to the router by typing http://routerlogin.com/basicsetting.htm or http://192.168.1.1 in the address field and click Enter or Return key.
c. A window will prompt for a user name and password. By default, the user name is "admin" and the password is "password".

Note: If you were unable to access the router's web-based utility, you may reset the router to restore the settings to factory default.

To reset the router:

a. Please push the reset button at the back of the router and release after 30 seconds.
b. Unplug the power adapter for 10 seconds and then plug it back in.

a. Click on Basic Settings.
b. Select Yes for Does Your Internet Connection Require A Login?.

4. Configure the wireless settings.

a. Click on the Wireless Settings under Setup.
b. Change the SSID to any unique name.
c. Scroll down, look for the Security Options settings and select WEP (Wired Equivalent Privacy).
d. Set the Authentication type to "Automatic" and the Encryption Strength to "64bit".
e. Leave the Passphrase field blank, select Key 1 and enter a 10-digit number.

Note: The 10-digit number you typed in the key 1 will be the password or network key for the wireless connection.

f. Click Apply button to save the changes.
g. Go to Router Status under Maintenance tab and check if there is an IP address under Internet port. If it's 0.0.0.0, do a power cycle.

5. Power cycle.

a. Power off the modem, router and computers.
b. Turn on the power of the modem first and wait for it to initialize, the lights to stop blinking.
c. Power back the router and the computers. Check if it will be able to get online.

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

What it sounds like to me is that your router has been running for a while, and thus start to break down slowly. You coul try power cycling it.

power cycling:
1.) Only unplug the power cord from the modem only, for about one minute.
2.) After one minute has passed, plug the power cord back into the modem, give it a few seconds to boot up again, and it should work.

If the modem still does not work, then the problem might lie with the computer itself, very hard to see happen, but it could still happen.
If in then that case, you would have to system restore your computer to an earlier date. that it was working fine on.
