Initially I had the same problem everyone else has complained about - slow loading of webpages, but fast according to Speedtest. To get it to work correctly, you need to turn off IP Flood Detection in the Services menu (apparently the modem decides that complex webpages are flooding the modem and throttles the traffic, when you shut off this setting, now you get full speed internet without any problems). To set it, connect to the modem at http://192.168.0.1, user: MSO, password: changeme (these are the defaults), click on Services (on the left), and uncheck IP Flood Detection. You still need to call TimeWarner cable with the MAC address for them to allow it on their network. After they did their stuff, I reset the modem (using a paperclip in the bottom for 10 seconds), but I don't think this was necessary (this was before I found the IP Flood Detection setting). (Time-Warner Cable wouldn't give any help at all (they suck), and neither will Netgear.)

After it is set correctly the modem works great and the WiFi works great too, actually working better/faster/more reliably than the modem/router that TimeWarner cable was renting to us. Best of all, it is $7 per month that we don't give to TimeWarner Cable.

I want to preface this review by saying that this is based off of my experiences with this modem. Just because it didn't work out well for me doesn't mean that it won't for you, especially if you're using an ISP other than Time Warner. With that said, I think it's worth while for me to put my experience out there so that you can make an informed decision.

I bought this modem because it was on the approved list for Time Warner service, the price was right, and it's a DOCSIS 3.0 modem. Seemed like a great buy. I mean, if it's on Time Warner's approved list, surely it will work properly on their network, right? Not exactly.

The tech came, made some changes to wiring, fired up the modem, got the MAC put on the network, and said everything was working great. A little while after he left, I tried and found that pages would sometimes load like they should, and then seconds later, would refuse to load. Then it would go several minutes before loading anything again, then back to normal. This intermittent problem persisted. Later in the day, I did standard troubleshooting (rebooting the modem, checking physical connections, hooking up using ethernet, etc.) and nothing worked. I tried multiple devices...same issue. Calling Time Warner tech support resulted in them putting the blame on the device and telling me to call Netgear. While I didn't (and still don't) disagree with them that the the problem was with the modem and not Time Warner's network, I knew that Netgear wouldn't help me either.

Some research helped me to discover that others have had the same problem, both on Time Warner and other networks. All the problems pointed to one thing: firmware. The firmware on most cable modems, including this one, is not user upgradeable. The ISP is supposed to take care of that.

The price on this was great!
Compared to the others it was 50-100 bucks cheaper!
It's well constructed. It's designed with ventilation in mind.
There's lots of areas for air to circulate and that's something I haven't paid much attention to.
It's also about 11 inches tall, has a nice wide base that's removable.
It can lay on it's side, stand upright and if the base is removed, be installed on a wall.
Directions are straight forward.
The modem controls and configuration are easy to access and easy to understand.
The WIFI set up is also the same.
It can be provisioned easily on Cox's cable network.
The lights are blue and green and easy to read on the front.
It's docsis 3 cable modem.
It has 4 wired ethernet ports.
It has a USB port and is a WIFI router in one relatively skinny package.
I paid $38.00. It's been great so far (at that price)

I bought this modem to escape from TimeWarner's egregious monthly modem rental fees. From all appearances, TimeWarner really doesn't want customers doing this, so they make the process of using another modem as difficult as possible. This is as close to actively penalizing customers for exercising their rights as I've ever seen.

[Update: I had to return this modem, but I'm not sure whether it was defective, or just flat will not work with TimeWarner as others have reported. I had fits getting it working right, but it was never stable, and would "lose" routes to some sites (but not others, oddly) semi-randomly. I replaced it with the much more expensive Motorola Surfboard SB-6141 (see my review of that one (in white) for more info), and my Internet connection has been minimally acceptable (as good as Time Warner ever gets: 7-15 Mbps and miserable latency on a nominal 30 Mbps link) since the change. I'm leaving the info below in case it helps someone else. I suspect the problem may have been with my particular unit rather than with the Netgear CG300D in general, but I'm not entirely sure.]

Here's how I got it to work for me, though (easy enough for anybody): When you get the modem, call TW and they will walk you through the process to get it authorized on their network (they will need the serial number and MAC address). At this point, they'll do some technical moogly-googly and tell you it's working. It will be, but only sort of. (In my case, here in Austin, the failure mode was similar to that noted in several negative reviews of this product: Initial page loads are painfully slow, but then things speed up to normal. Simply loading the speedtest (from either speedtest.net or speedtest.texas.rr.com) took forever, but then the test would report decent speeds.
