Windows 7: Cable Modem Gateway + Router

15 Jul 2011   #1

Windows 7 Ultimate 64-bit
Cable Modem Gateway + Router

I am connecting via Time Warner-Roadrunner with a Netgear CGD24G cable modem gateway.
I am always having trouble with DNS.
DNS is not able to resolve IP addresses.
DNS Server isn't responding.
Pages are not usually opening and most of the time when I click refresh, nothing is happening. Refresh button appears in 10% of a second.

I don't know how to resolve the problem. I can try connecting via USB, but I haven't found the driver for it yet. Thanks to NetGear, there is no driver on internet or in the resource CD.

The other solution I am thinking is using the D-Link DIR-615 router. I am thinking to add it to the CGD24G gateway (because DIR-615 doesn't have a coaxial cable input). They obth have as default address. How should I change the modem and router gateway addresses? Should I change the CGD24G to (which I already did actually)? When I do that, do I need to change the IP addresses

from -
to another range or leave it the same?

Do I need to change the IP addresses or the subnet mask on DIR-615 if I add it?

Is there any solution for DNS and Key Ports problem with CGD24G on a Windows 7 Ultimate x64 OS?

Does anyone have a USB Driver for CGD24G?

I hope I could make myself clear. English is not my mother tongue, and my expression of my thoughts can confuse native speakers time to time.

One of the problems you have is that router will severely limit your internet speed. I had one with the comcast connection and it dropped me from 21MBs to 6 MBs. Once I trashed that and went with comcast's modem I was back up to full speed. Seeing how you pay roadrunner, I had them when I was in TX., I would call them and tell them that you want to switch to AT&T. Not that you really are intending to but let them know this. Then tell them the problems you are having and that is the only reason you are thinking of canceling with them and switching to AT&T. Watch how fast they quickly offer to resolve your problem by sending a Tech out for free and fixing the problem for you. They key word here is you have to tell them that you are thinking of canceling with them and switching to AT&T. That should fix your problem with no headaches on your part! Post back to what they reply with you.

I already had technicians giving me different modems. They told me that they did check the box too, I don't know what they did. The thing is CGD24G is a cable modem gateway and I don't know how good it is about routing capabilities. I am sick of refreshing the pages and seeing DNS errors. So, technicians came here, but all they did was changing the modem gateways and checking the box, but I am still having the problems.
Thanks for the warning about the lower internet speed.
I don't have AT & T service in this building, and I am stuck with Time Warner if I want a broadband connection.
Thanks for your tips and reply.
