Customer Ratings & Reviews

I wanted to cut out Comcast rental fees since at the end of each year they equated to the cost of a router or modem. Free PSA for everyone: a separate router and modem combo is always better performance wise, and in long term financially than an all-in-one router-modem like the one you get from Xfinity. I upgraded my parents internet to 250Mbps and while I was at it, decided to get rid of the rental equipment from Comcast. Granted this router is overkill for their needs since it can provide 680Mbps according to the specs but it does provide future upgrade ability on their internet plans. This is certified to work with Xfinity and you will need to get a separate router to get wifi. I had to return the initial one that I bought because it was DOA (Dead On Arrival) but that happens with any tech, and the setup and installation was easy. If you're wondering whether to part ways with your rental box... DO IT. It's really easy to set up a modem and router and you don't need to know tech to be able to do it. I have one of these routers for my own place, its been reliable and hasn't dropped a connection yet.

I purchased this to replace an existing modem that I had, which due to channel bonding, was not capable of achieving speeds higher than 100 Mbps on Time Warner's service. This modem's channel bonding is 16x4, allowing it to achieve the full 300 Mbps service (perhaps higher, if/when they offer it). It's also cheaper than the Motorola SB6183, the only other modem I am currently aware of that can support the 200 Mbps and 300 Mbps tiers. The modem was extremely easy to activate. I simply unplugged my old one, hooked this up to the coax cable, and connected an ethernet cable to my computer. Within a minute or two I was able to launch a browser and visit www.activatemymodem.com which was simple and painless. The modem started working right away and at that point I disconnected the computer and connected my wireless router, completing my network setup. The modem generally tests above the maximum bandwidth of my plan. I have the 200 Mbps plan with Time Warner and I have tested as high as 225 Mbps down and 23.5 Mbps up. It has been powered on and rock-solid since I connected it one month ago. The LEDs to indicate status are visible but not obnoxiously bright. I highly recommend this modem!

I have two online gamers in the house and we are definitely reaching our internet capabilities without even trying consistently 1.2 terabyte of Internet a month with 4 computers 3 smart tvs and..... alot of gaming consoles (not all used at once obviously) but this Internet modem gets hot really hot, hasn't died yet but it definitely needs a restart and cool down halfway through Sunday but still going strong And it's pointless to buy the more expensive router Because the Internet coming to our house is not any faster

Dumping my Comcast/Xfinity cable TV service, picking up Netflix and Hulu with Live TV and combining this modem with a WIFi router saves me a bundle every month and I can still catch the NFL games! Since the Comcast/Xfinity modem rental has gone to $13 per month, the $70 cost is offset within a few months. I was also able to move the WiFi to a more central location in my house which gives us much better dual-band coverage throughout. Yes, the modem runs warm but not extremely hot. I have it sitting on top of a bookshelf in my home office with 4 to 6 inches of clearance around all sides. I've been running it for about a month and have not needed to reboot it at all. In that time frame, I would have had to power cycle the Comcast/ Xfinity gateway 3 or 4 times to regain internet connection. Overall, I'm very happy with this modem. My only "wish list" addition would be an ethernet connection to go directly to my desktop PCs in the same room. But that would require the addition of an internal router which would increase the cost.

I like the modem a lot. No issues so far. It was very inexpensive. It was easy to setup. The longest most annoying part was dealing with my cable provider to update their system with the new modem info but that was on their end. The modem its self has been great, I’m getting strong internet speeds. I hope it stays that way. Best of all, I returned the piece of crap modem/router my internet provider was overcharging me monthly for. Within two billing cycles this modem has paid for itself.

Finally switched my Motorola SB6131 to this model after Comcast upgraded my line to 150Mbps. The Moto box wasn't handling it very well but this one worked like a charm and runs very cool. ++ Easy setup ++ XFINITY was able to recognize it immediately and also pushed down a firmware upgrade as soon as it was connected -- My only complaint would be that the modem was built to sit on a flat surface & the base is one piece with the body. There is no way to mount the modem like you could with Motorola.

Easy to setup, reliable and affordable! Signal is very good! we had for long time an Arris SURFBoard modem and at the end it needed to be replaced (it needed to be rebooted almost everyday) .......this time we decided to move to a different brand and try NETGEAR. We can say we are pretty happy with our new modem...no more connection lost!

Moved to a new apartment in Pittsburgh and needed to establish service with Xfinity. They offered to rent me a modem for $10 a month, but I opted to buy this one to save money long term. The modem was easy to set up, and exactly what I needed. The connection is fast (60-70 mbps down, 4-6 mbps up) and reliable. The product was exactly what I needed at a reasonable price with no extra bells or whistles.

Bought this cable modem to replace the modem I've been renting from my cable company. Set up was incredibly easy - it took longer to get Customer Service from the cable company to answer my call to activate the modem than it did to unpack, install the cables and reboot the computer! Speed and reliability is great - I've had it working for over a month and never had to reboot the modem even once. Priced right at B.B.

For our use case this is a great modem, and far less expensive than renting one from our ISP. At the prices we got this and were offered to rent by our ISP it pays for itself in 4 months. It is not good for those wanting a true gigabit connection. It works well up to about 500mp and is perfect for a 300mp or less (we are currently using a 50mp, but have run it on a 300mp). If you are getting a gigabit connection you will need to purchase the next model up from here, but for most home/office situations this unit is great. We play online games, while streaming an HD movie, and someone surfing the web with no bottleneck or buffering issues.

No issues. Needed to make the typical call to my service provider first (in my case, Time Warner cable), so that they could do what was necessary on their end to recognize this new cable modem. Once connected, my cable modem has been working fine ever since. I've not had any connectivity issues, so my experience is that I'm just as happy now, as I was previously when using the leased cable modem from Time Warner. The only difference is (of course) I now own my cable modem and don't have to pay the ridiculous monthly lease fee anymore. It works well while connected with my Netgear router too. Also, while physically at the Time Warner Cable center for returning my leased cable modem, I overheard a couple having a conversation about their internet. I chimed in and informed them about this product, and told them I'd recommend they take this approach rather than leasing. I also told them where they could find this product (Best Buy).

Bought this instead of paying $14/month modem rental fee for rental property. Easy to set up and use. Getting fast internet as described. was able to get it on sale so even happier at this point. We will see how long it lasts but so far so good

I have this paired with an AX6000 and haven’t had any issues. I have lots of smart devices and haven’t had any bottleneck issue. Running 400gb service from spectrum without any faults. Took about 15 minutes to talk to spectrum to get it setup. I would recommend anyone to get this over a modem provided from you ISP. This isn’t top of the line, but much better than most options. I think if I did it again I would get the top of the line surfboard instead, but I don’t have buyers remorse what so ever.

Fabulous cable modem. Great price point and performance. Paired with a midrange router and couldn't be happier with the performance achieved. This was a great investment for the area I live in because the modem will have the ability to handle higher speeds as they become available. Runs cool to the touch with 24/7 use.

Let me tell you, this modem Is on my Top 10 best purchases that I made in my entire life. This modem kicks butt! Before I got my Netgear modem, it used to take almost 4 hours to watch a 2 hour movie because of buffering. And of couse rewinding! I would get so irritated that I would give up and stop the movie. Since i've been using Netgear modem, the only time the movie pauses is when I pause it for a snack run or b'room break. The only advice I have is unplug it every 30 to 45 days, if not, an error message will appear and you wont be able to connect to the net.. Unplugging the modem will allow for updates. Do this if the modem is in use 24/7. (I forgot to mention that I also have the Netgear router, which is badass too.) I have no complaints, easy to set up, easy to follow instructions,.Both are very good products

I upgraded to this Netgear modem from a DOCSIS 1.0 cable modem which along with an older router was limiting me to only 15 Mbps. Now I get the speeds that I am paying for and am surfing the internet super highway at super highway speeds. The Wirecutter (https://thewirecutter.com/reviews/best-cable-modem/) has listed this modem as one of the best and it has lived up to the reviews. Best Buy price matched the modem with another competitor and provided excellent guidance to help me select this modem. Set up and configuration were very simple and took me about 20-30 minutes via web chat with my cable internet provider.

I purchased this modem after Time Warner to informed me that they are increasing internet speed by a factor of 10 with no increase in cost. WOW! So I need f a faster modem. This was on the Time Warner recommended list. Easy to set up with one call to Time Warner to activate. Flawless performance.

This modem fits the bill for speed and price that meet our household's uses. Thanks to the others who also gave it a vote of confidence to help with the decision to go with this one. Easy set up. Taller than an Arris Surfboard and old school style look, but functionality was key.

I bought the Netgear cable modem because I currently own a Netgear router and wanted to ensure compatibility and easy pairing of the two units. The modem was easy to set up, has been glitch-free and was perfectly compatible with my current TWC provider service. Very happy with the purchase.

The name says a lot about this cable modem. I've installed several of these on Comcast (Xfinity) networks at various locations. They're very easy to install and almost configure themselves. There's no WiFi built-in to this unit. You'll need to get a stand-alone WiFi router to work with this (but only if you want WiFi). There's no point in paying someone else in order to rent their cable modem when you can purchase your own CM500. I've had excellent results from each of the CM500 units I've installed. I highly recommend these cable modems for use with Comcast networks. My experience with these have been at internet speeds of 150 Mbps or less, but they're rated for much faster than that.
