When I connect my modem to my laptop, all the lights come on except the pc link light. I have already unplugged it and reset it and it still doesn't work. What more can I do?


If the ONLY light not illuminated is your PC link light then that generally indicates a physical disconnect between the modem and the laptop. If you can get the PC link light to light up when connecting to any other device (computer, router, anything), then you are most likely looking at the ethernet jack on the laptop being burnt out. Otherwise, try swapping the ethernet cord. If a different ethernet cord does not resolve the issue and the PC link light does not come on no matter what the modem is plugged into, you are looking at a faulty ethernet jack on the modem.

How can I install a wireless router to RCA cable modem DCM425 installed by Time Warner?


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.

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

Ethernet vs. usb


FYI for those people trying to use a ethernet and usb cable from a cable modem - it may work for a while but it won't work forever - your ISP will only allow one IP address out of the modem unless you pay for additional addresses (then you need a switch). Each device you have on the modem is fighting for that IP and eventually it will just quit working (if it works at all).

If you want more than one computer on your network (on the Internet or sharing printers/files, etc) then you need a router or a gateway (cable modem/router combo which I DON'T recommend).

Take the modem out and look for any brand names such as aztech etc and look @ the chipset to discern what kind of modem it is.

Bridge RCA Thomson DCM315R


Hi,

Usually cable providers provide public ip directly to your company ( already bridged ). so no need to configure your modem to bridge.
- Connect the computer directly to the modem and if possible, let me know the ip address of your PC, So we can find the modem already bridged.
- If its already bridged, then Open the ports on your Router ( port number : 3389 for TCP ) or else you may try DMZ Host on your router to check whether it works.

Note:
DMZ ( Demilitarize Zone ) host which opens all ports on your network and shows ur computer to the outside Network which is not really secured one. but you can try it for testing purpose whether it let you to use remote desktop.


Hope this will help you
