NETGEAR DOCSIS 3.0 - High Speed Cable Modem (CMD31T)

I ordered a Motorola Surfboard modem from Amazon because I previously had a Motorola Surfboard modem that was about 3 or 4 years old, and I was having problems getting onto the internet, having the internet drop once I did get on, and I could not get my email to my iPhone and other little problems. When it came, my cable company couldn't even get a signal to it. So I sent it back and ordered this awesome Netgear modem. I can't even tell you how much difference it has made for my computer speed, internet drops, etc. I got the modem, took it out of the box, plugged it in, called the cable company and was up and running in less than 5 minutes!! I am now getting a download speed that is much faster and I haven't had a dropped internet connection yet, and my iPhone email started working again. I am using this modem with a Netgear Router and it is just a great set-up. Very happy with everything.

Purchased modem and installed November of 2013 using Time Warner Cable, this modem kept dropping the signals could not keep connection. Also NETGEAR told me to password protect modem, password got messed up, hit the reset button on the back per Netgear and Modem would not reset to the default. NETGEAR informed me that their is a problem with this modem and it may extend to anyone who purchased this modem where the reset button, is not truly clearing all the settings. The MOTOROLA SB6141 non wireless modem works better and stays connected also support the Super High Speeds of Timer Warner Cable where the CMD31T does not and this is on the Time Warner Website when looking for Modems that work on their system, they have a webpage. The CMD31T keeps dropping all signals which I confirmed with Time Warner, and it kept dropping out of there system even though this is TWC approved. The most annoying part is that there were no cable outages and my signals were excellent from Time Warner but this Modem, if you unplugged it, or used a router with it, would drop the signals in a second. Constant Dropping of signals, yet Netgear had no clue other than to return the product. I even wonder if the NETGEAR Engineers fully tested this modem with all the problems, and read the reviews on other re sellers websites not very good. It did not work for me. I am reporting facts and statistics, and I have read the reviews, where one of the top executives admitted they had a problem with this modem and they were trying to work it out. Look I cannot tell someone what to purchase or buy, but I can say for me this modem had be reloaded into the Time Warner system about 6 times, it kept dropping, so I went and got a Motorola and it works fine, these are both good companies but NETGEAR Modems are trouble. Yes this was a Time Warner approved modem. Update Purchased a Motorola SB6141 Modem only, this modem does not support wireless, you need a router for Wireless. This Modem worked faster and much faster then the NETGEAR CMD31T. I ran Latency testing speed testing direct connected and the Motorola ran 5mbs faster than the NETGEAR and the Latency test showed 10ms faster on the Motorola. NETGEAR has some issues with this Modem, these are the Facts, sorry NETGEAR after 3 hours of customer support and at the end saying there was nothing that could be done except to return the product, took NETGEARS advice return the Product and on my own research purchased the Motorola SB6141.

Its a modem and it works. TW Cable seemed to have issues getting it to work when I called them. Even though this is listed on their website as tested and a preferred item. They are the only cable company in town however and I have tried the alternate internet providers or know folks who have. They know they are the only real game in town. The modem seems to do everything I want it to do. It is, so far, more reliable than the Surfboard that TWC gave us. It was shipped quickly and I installed it easily enough. I am getting a pretty even download of 14.3 to 15mb from it. Compared to the wildly fluctuating 200kb to 27mb from the old TWC modem. A much higher upload of 800kb to 1.1mb compared to the old modem that ran anywhere from 200kb to 650kb or so. At least I don't have to reboot the whole system once a week any longer.

I've had Netgear brands for the past 15 years at a residence based network supporting 6 desktops and in recent years, wireless. In 2012 that network was overhauled and based on CAT6 cables with new Gigabit routers and switches. All the new hardware works perfectly and at advertised speeds. This modem was purchased to support internet access to the local cable company as they no longer supply modems and/or wireless modems at no charge. This purchase will give an easier ISP option when the local phone company and cable company price per month are far apart from each other. As it is now, Verizon and Time Warner are not equal in cost and what comes with that cost per month so, this makes it easy to simply change ISP's without being stuck to one monopoly or the other. Cable companies use DOCSIS technology so this is a must have while the phone is still including their equipment with the monthly cost. If moving to cable we will save the modem fee and still have our Netgear N900 wireless router behind the modem inter-connecting our network. Once the cable prices go up as they do after a set period of time, something I call disloyalty time, we can move back to Verizon Fios in 5 minutes and keep that until they apply the "disloyalty" prices and we move back with cable.

Rated this 3 stars (considered only 2) because... 1) It works with Comcast as I purchased it to get rid of their rental fee. 2) It worked well when it was working (no drops, constant high speed) 3)....it died in a month. I still don't know if I had a lemon or...if Comcast did something. The timing of the death of this device is still suspect. Quick summary: - Ordered it in mid December. Had issues with the self activation process. Called support line and tech activated easily when I supplied the info. - Worked fine throughout December into January. Never had to reset it ever. - Realized Comcast tacked on some false charges to my Dec bill. - After two days of getting Comcast to remove the false charges...modem completely dies. So the 3 stars is more of a 'neutral' stance as...it worked well, but died quickly for whatever reason. Sent it back for a refund. Just be careful I guess?
