Bridge RCA Thomson DCM315R

I am trying to use remote desktop. My computer that I am trying to connect to has the setup of Cable Modem to the netgear router wired to my computer. I believe that I need to setup my cable modem to bridge to the router otherwise I think I am dealing with two different internal ip addresses and i believe it will confuse my system. I tried port forwarding from the router but It still doesn't find my computer. Any thoughts?

Re: Bridge RCA Thomson DCM315R


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.

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

How to connect a rca thomson router to wifi

You are trying to connect to a modem, not a router, the router, a wi-fi version, is what you are connecting to your network.
First, power off all equipment, computer and modem, use the network cable you have connected to your computer from this modem and disconnect from the computer, connect it to the differently colored port on one end of the Belkin, the others have numbers, connect a network cable from one of the numbered ports to the computer.
Now power on the RCA modem, wait until lights are steady, then turn on the new Belkin router, wait until lights are active, just a few moments, then power on your computer, you should now have internet access and be able to locate the manual from the Belkin's website to further your setting up a passphrase or setting up some security on your wi-fi.

I have a RCA Thomson DHG 535-2 without the disk for the installation and the ethernet wont help everything is hooked up etherent/cable to tv power yes... and that's about ti all im really missing is the...

Thomson Cable modem has an ethernet connection...
The ethernet connection goes to your computer via a standard Cat5e patch cable. There is no USB that I know of...
Cablevision wire goes to the modem. It should be the first device on the cablevision wire. If you need a splitter, it needs to be a GOOD one, connected DIRECTLY to the incoming Cablevision wire as it enters the house. Use good copper wire.

Order of events:
Connect the cablevision wire to the Modem.
Connect the Ethernet cable to the computer and the modem.
Power on the cable modem.
Right click the network Icon near the clock and click 'repair' (Or reboot the computer)
Apply for and get an account for cable Internet from your Cable company.
After a few days, cable Internet should work.

Cable modem

Go and buy a router. Plug your existing modem into the WAN port and your computers into the LAN port. You could even get a wireless router and connect your upstairs computer wireless. Be sure to lock down your SSID (Wireless Access Point Broadcast Name) so your neighbors or people driving by don't get on and do bad things on your network.
