Do not purchase this modem for use with Comcast!! I purchased this modem, off of Comcast's approved list in January, to replace my leased modem from Comcast. I worked fine until April,1. That was when, in my area, Comcast began their update from IPv4 to IPpv6. This modem has a known error in its firmware in which it will not allow Comcast to update it firmware to be able to work with the IPv6 changes. I have spent over two months trying to get Netgear to either fix the modem, update the firmware, or refund my money. So far it has amounted to nothing. Netgear has sold a bad modem and is now trying to covered up their mistake by pointing the finger at Comcast or drowning their support customers in endless requests for screenshots that have already been provided and other useless and repetitive information request. I now seem to be between a rock and hard place and it would appear that I will have to purchase a modem from a different manufacture that will actually work.

1 August Update:
After 4 months of going back and forth with Netgear and having them send me two different modems after they accepted that the problem was the modem, not Comcast service, I finally gave up. I sent their modems back and requested a refund. As it stands right now, Netgear has cut all communications with me, will not respond to my voicemails or emails. So I am screwed out of $90. If I could I would give the company and modem zero stars. Avoid at all cost.

You should know that Netgear does not sell this modem to individuals, only ISPs. At least that's what Netgear keeps telling me. It's pretty frightening when a company that is supposed to be a major internet player can't do a Google search to see that over 100 stores sell this modem directly to users.

My CMD31T died six weeks after it was purchased. One day it was working fine and the next day I had no internet connection with my ISP. First I called my ISP and did all the stuff they asked. Then my ISP sent out a technician with a network analyzer. My connection was fine, the modem was not. Then the nightmare begins.

The Netgear support number connects to a call center in India. Everyone there follows the script EXACTLY. The first Customer Service Representative (CSR) told me that Netgear does not do support for this modem, I have to call my ISP. I call my ISP to check and they confirmed that since this was a privately purchased modem that Netgear was responsible for support. The second CSR had me do a bunch of diagnostic steps. Nothing worked, but since I could still see the GUI in the modem, the modem MUST be fine. The third CSR told me to call the ISP and when I asked to speak to a supervisor, blew me off. The forth CSR said someone from Netgear would call me. I'm still waiting for an RMA so I can return this modem two weeks later.

BTW, forget any support if you run Linux. You can tell the CSR your IP address, DNS, and default route, (which are MUCH easier to find in Linux) but if you are not running windoze they tell you they can't do support.

The technician from the ISP recommended Arris or Motorola. I bought a Motorola modem because I might not ever get an RMA from Netgear.

My father in law bought this as TWC has told us they are now going to charge a 4$/mo fee for their modems and he wasnt down with that so he bought this. His speeds are triple what his TWC account services are supposed to be. Probably because TWC cant regulate the speeds on it with their account system. Only thing is the desc says this modem isnt supported by TWC? I wonder if thats a deal between Netgear and TWC so their users dont switch to this modem and unlock full speed. I will post an update if anything goes bad with this product and TWC.

Bought this before reading the reviews, and it turned out to be total junk. My cable company, whose name is prominently displayed on this thing's box, spent 2 hours on the phone with me and we could not get this thing to work at all, so came back here to Amazon and went with a Surfboard - which worked perfectly out of the box, took the cable company two minutes to activate and done. Do not waste your time with this turkey. Too bad there isn't zero stars.

Bought it for my the comcast cable internet. Comcast has certified this. And the box in which this comes boldly displays the certified by comcast mark.
But It barely worked I kept having troubles like losing connection and finally one day it completely stopped working.
The Comcast technician who visited my place told me many other people faced the same problem with this one but Comcast refused to officially remove this from the list of certified modems.
Finally now I am using a surfboard and it does not have any problem.

Do not buy this modem! We have had this modem for a little under 5 months, and have had continual issues with it needing to be reset if more than one device is connected to the internet. If you look at this product 's reviews from other sellers, you'll see this is particularly a problem if one of the devices is an apple one (Mac, iPhone, iPad). We've also had issues with it on PCs, Kindles, and Android devices. Another incredibly frustrating thing is that NetGear will only offer live chat product support within 3 months of purchase. My attempts to receive email product support weren't answered because I don't have "proof of purchase" i.e. the original receipt from 5 months ago, even the expensive product malfunctions 30-40% of the time, and the 60% of the time it still needs to be reset several times a day.
