It was time to start trimming my Time Warner Cable bill. So, I purchased this puppy. Yeah, it has a cheap price tag, but this little baby packs a punch. I pay for the Extreme package via Time Warner. I was averaging 80 megs down. After installing this and getting it activated, my download speeds are averaging over 115 megs down – that’s both wirelessly and hard-wired. The setup is simple. 1. Remove your current cable modem. 2. Put this one in it’s place. 3. Hard-wire it to a laptop or a desktop (yellow cable to the yellow port on back of cable modem, the other end to the internet port on your laptop or desktop. 4. Power on the modem (making sure you have already connected the coaxial cable as well. (When the globe stays a solid green with no blinking, it is recognized as being connected. 5. Turn to the activation page in the mini manual that comes with it. It will show various internet providers and their perspective links. 6. Open up a browser (with pop-up blocker offf) and follow the prompts. Odds are in favor you will get “due to your account settings, this will not work – call the 1-800 number shown.” That’s okay, call it. Tell the operator you are installing your own cable modem. The operator will ask for the MAC address (found both on the box and bottom of cable modem). Agent on the phone will first remove your current cable modem from your plan (or else, this will never work). You will power it off upon request, and back on again 30 seconds later. Go to a website of choice – and wa-la, you are back online!! No more cable modem rental fees!! BTW, I work in the IT field, and have for 25 years. This will be all the modem you ever need unless you plan to go over 450 megs in the future. I have the following items that may be online at any time and all at once: Xbox One, PS3, Two laptops, One desktop, one cell phone, and one tablet. I can play Netflix on all devices (4 at once since that’s my Netflix account package), and there is no buffering at all. I bundled this with the Netgear WNDR4500 Dual Ban Gigabit Wifi Router. Here’s my layout. Cable Modem feeds the router. The router feeds my 16-port switch. I work on computers on the side, so the switch comes in handy. Any questions? Feel free to ask me. Trim your cable bill and get this or any cable modem for that matter. Note, this is a cable modem only that does not supply wifi. It only has the internet-out port. There are no other ethernet ports on it. So, upgrade your router or get one. The model I mentioned above is a great match. You are welcome!!

We installed it this morning with zero issues.. Followed the quick start instructions provided. Since our main computer isn’t wireless, we didn’t have to call comcast to do a thing, the modem was automatically detected and an xifinity webpage opened with prompts to finish activation. It couldn’t have been any easier. Our phone and cable were working instantly when the set up completed and when we turned our router back on that picked up with no issues either. I’ll write a follow up review if we detect other good and bad as we use it more but wanted to pass along how pleased the set up was for those looking to stop spending $10 (soon to be $11) a month to rent Comcast’s modem.

Five minutes after arriving on our doorstep, the new cable modem is up and running. Bracing myself for difficulty with Comcast, I was pleased at how easy setup was without ever having to speak to Comcast’s clueless CS. Using a laptop with an Ethernet jack, here’s how easy it was:
1) Wrote down my Comcast account number (This is the MOST important step!!!)
2) Connected modem to cable, power, and phone line
3) Connected Ethernet cable to modem and computer
4) Waited three minutes for the first three lights to blink steady (they’ll blink and flash while the modem is syncing. You could wait up to 10 minutes for sync).
5) Turned off WiFi
6) Opened web browser, and Firefox had a nice little ‘show login page’ button appeared (if this doesn’t show, you can go to xfinity.com/activate)
7) Entered my account number and street address
8) The modem reset itself. I plugged that into my Luma and we were off to the races!
Ironically, Comcast sent a new tower modem a week ago. I don’t know if it’s me, but this seems faster than that did – speed about the same but ping time is now 9ms instead of 14 and pages that seemed to load slowly before pop in immediately. Biggest bonus is that we’re saving $11/month going forward.
UPDATE: 4/5/18 – Everything was working perfectly until Comcast turned off my service this weekend because the modem wasn’t registered in the right database and Comcast thought I had no equipment. Object lesson: After activating online, call Comcast to make sure the equipment has registered across all of their databases – 5 minutes could save you 2 hours! The modem, however, is working flawlessly and I still highly recommend it!

The Netgear CM600 cable modem is an ultimately reliable DOCSIS 3.0 cable modem for service speeds up to 300 Mb/sec or faster. Unlike the company’s CM700 model, it does not incorporate the troublesome Intel Puma 6 chipset found in many higher-end cable midems, making it a more reliable choice.
There may be a downside for some, having little to do with the CM600. When accessing the CM600 interface, it is noted that ALL firmware upgrades can only be provided by the ISP (in my case, Spectrum). Whether Spectrum will upgrade said firmware (when and if necessary) is questionable, though it would be to their advantage.
It has also been explained that Spectrum cannot remotely troubleshoot issues in “non-standard,” cable modem/routers. These being anything other than the standard free cable modem/routers Spectrum installs as part of their service. They can, however, initiate a reboot and validate that the CM600 is functioning.
Funny, this seems more like a positive for me! As a trained network support technician, I like the idea that Spectrum cannot manipulate the settings of either my modem or router; something I am more than capable of doing on my own.
Setting up the Netgear CM600 cable modem is as easy to setup as plugging it in and turning it on. The CM600 was fully functional within seconds of connecting the Internet cable to the back.
The CM600 is a one-trick pony; it is a cable modem and nothing else. It converts cable data into Internet data. Given the specifications and the high-quality components it does its particularly job incredibly well. The CM600 is built to pull a signal out of a weak or “noisy” line. It will continue to provide Internet service when other lesser modems will drop out. Since purchasing this modem, I have had no random cable dropouts from my ISP. Remember, it has no built-in wireless or wired router. Such a router must be purchased separately.
A quick aside: The router is the Grand Central Station of your home’s WiFi universe. It takes a tremendous amount of efficient but fast processing power to send and receive multiple data streams quickly and effectively between a houseful of smartphones, smart HDTVs, computers, tablets, cameras and other WiFi-enabled gizmos and the Internet. A router is a radio transceiver. The more powerful it is, the more information it can send through the air over longer distances. The more sensitive it is, the more it can pick up data being transmitted 500+ feet away. To get the best benefit from your Netgear CM600, I recommend the Netgear Nighthawk® R7000P. Built to handle the needs of the tech enabled home, it is a stellar dual-processor performer at an incredible price.
No. I don’t work at Netgear!

I have a sudden internet connection issue and Spectrum customer service stopped by to check internet connection. It turned out that Netgear CM600 I recently installed was defective. When I reconnected my old Motorolla modem, all internet connection worked perfect. Since 5 month use, CM600 was out of function. I am going to contact Netgear. But it was very uncomfortable to deal with all the issues raised by no internet.
Through Netgear tech support, I found out it is not due to hardware issue, it was due to loss of information from ISP (Spectrum). Even Spectrum tech support could not solve my issues. I contacted Netgear and Spectrum a couple of time. Finally one of Spectrum tech support team fixed my issues. It turned out firmware updating issue. Final conclusion is that the hardware is perfectly fine.

Very frustrated that I spent two years struggling with my internet service which I blamed on the provider only to find out recently that my modem was the issue. I only ever got around 15-30 Mbps out of this modem despite paying for 100Mbps internet service. Once a different modem was connected, the issue was resolved and I was receiving over 100Mbps based on speed tests. All along it was the modem that came with good reviews and was certified for use with Comcast Xfinity internet which is what I have. I wasted hundreds of dollars because of wanting to save money on equipment rental fees and purchasing this modem. I am purchasing a different modem but annoyed I am out the money I spent on this and the service I wasn’t getting because of this modem.
