Question about Comcast XFINITY

Connecting MacBook or NetGear Router to Comcast

I have the NetGear 150 wireless router and can't seem to connect it to the Comcast VoIP modem they just provided. A Windows 7 computer connects with a direct connection to the modem and I get a good internet connection with that. I cannot connect either of two Apple PowerBooks to the internet with a wired ethernet connection. Comcast has been of no help so far; it seems they sell the service and want to charge $ 50 extra to allow you to make a proper connection to it. Oh yes, there's one more thing, the installer installed and exe program on the Windows system before connecting it up to the router. I suspect there's some setting's in that program that form a separate password authentication with the modem that the router and MacBook don't know how to do. So here's the question. What peculiarities has Comcast incorporated into their connection protocol? What information do I need to get from Comcast so that I can connect Apple products or the NetGear router to the modem? and, how do I enter them on the input screens? Any help provided would be much appreciated.

    The problem has been resolved.  The Comcast VOIP modem's firmware is configured to require registration of the ethernet MAC address of the connecting device be it computer or router.  The software that the installer loaded on the computer allowed this connection to be made and registered the MAC address of the computer on the modem.  So, without that software and without the modem's manual, you're at a loss to make a connection unless you spoof the MAC address of the connected computer on the router. The NetGear router is designed to permit you to this, so devices connected either wirelessly or by wire to the router will then see the internet.  So, the solution -- find the MAC address of the ethernet card on the computer Comcast initially set up the router with and program that MAC address into the router.  My son figured this out after several hours of internet searching for an answer.

As a Comcast tech I assure you there are no special protocols used on a standard residential installation. There should have been nothing the tech downloaded to your pc most especially an executable file. I would assume he or she was making sure you were able to get to the customer installation page before they left. However if you have a router that the ports are not functioning on you are most welcome to have one shipped to your home for replacement. The wifi key provided on the bottom of the router is case sensitive most generally all in caps. If you dont have a spare cat5/6 cord to see if thats the issue ask them to send one with the new modem. Comcast does not charge you a fee for a truck roll when its faulty eqt. of their own. I have installed hundreds of apple products including the ones you are referring to as well as netgear routers they all work with the gateway Comcast provides the customer. Now if you want there is a tiny factory reset pin button at the very top of the gateway in the back you will need a paper clip to push it in. Hold it in there about 10-15 seconds and the gateway will reboot and return its setting to factory spec. try that first before calling customer service.

How to reset rangemax wireless-n 150 router?


Reset means that you will restore it to factory defaults which will delete all of the configuration settings of the router and will leave you not connecting to internet and wireless as well, but if you really want to reset it, just simply press the black button at the bottom of the N-150 router, press and hold it for at least 15 seconds. Once the lights on the router starts blinking, that means that it is successfully restored to factory defaults.

Zoom 1079 modem works fine on its own, but internet drops out intermittently when I add my Netgear N-150 wireless router for use with Netflix... Rene.


If you're connecting the device you're watching netflix with wirelessly, check the strength of the signal your device is getting from the router, netflix needs a strong connection and the download speed you'll need for it is 1.5mbps or greater. If both your signal and download speed are fine try unplugging your Netgear and your Zoom from the power for about 5 min. to refresh your connection

If you connect the computer directly to the modem, does it work?
If that works then the modem is working.
Now connect the computer to the router and the modem to the router.
You will need to open the set up page of the router to check the settings of the router.
You can set up the router without the CD also.
It is very easy.

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

Netgear wgt624 just stopped connecting to internet


I encountered the same problem, with the same modem and also Comcast, and here's what wound up working for me, after time spent with a nice guy on the Netgear customer support line:

1. Log into router: http://192.168.0.1 (or 192.168.1.1) - user: admin / password: password

2. Under Maintenance, click Router Status. If IP Address is listed as 0.0.0.0, there's your problem-- router isn't getting address from modem.

3. At bottom of Basic Settings, under Router MAC Address, change selection from Use Default Address to Use Computer MAC Address.

4. Click Apply.

5. Click Router Status again-- non-blank IP address should now be listed.

6. Basic Settings will now show MAC address under Use This MAC Address. See if you can get online now. I could, and I hope you can, too!

Only real trouble shooting I can suggest is power cycle the modem and router. If you have the Comcast Digital Voice modem make sure you push the reset button on the back as there is a battery in the unit and unplugging won't do anything.
