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

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.
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.

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.

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.
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.
