abunda_amazon_reviews 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!;;Reviewed in the United States on March 21, 2018;;5.0 out of 5 stars;;Bam! Saved $11/month in 2 days and 5 minutes! (UPDATED 4/5);;CM10014;;/gp/customer-reviews/R70JNULWDBVGK/ref=cm_cr_dp_d_rvw_ttl?ie=UTF8&ASIN=B06XGZBCKP;;;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.

Average Guy, not a techie
We have Comcast, this modem is supported by Comcast and it’s super easy to set up. It took less than ten minutes. If you have Comcast there are specific instructions to set it up. Very easy. The modem works so far. Our internet speeds are where they are supposed to be. Stop renting your modem and buy it! As for technical stuff I have no idea what any of it is without googling something. I paired it with a LINKSYS EA7300 wireless router and am now enjoying way better connectivity.

Trouble
I have had this modem for a little over 6 months and it has not been reliable. It was fine for the first three months but then it started loosing connection. I would restart the modem and it would work okay for awhile and start acting up again. All morning it has been working for about 15 mins and then it’s down. I’m glad that I forgot to turn in the modem I had been renting from my ISP. I hooked it up and have not had any trouble. I am so disappointed in this modem. I am normally a Netgear fan but this has been nothing but trouble. I do more streaming than anything and I have work I have to do on my iPad a lot and this is unacceptable.
