NETGEAR Cable Modem DOCSIS 3.0 (CM500) Compatible with Major Cable Providers Including Xfinity, Cox, for Plans Up to 400 Mbps

I recently purchased this modem and a Netgear router to replace a 2-in-1 product made by Arris which was total garbage. I paid ~100 for the Arris product which was suppose to have wifi signal boost, produce up to 100 mbps signal and had a warranty but the product was defective. The average signal strength of the 50 mbps I was paying for was 1-3 mbps and that machine needed restarted literally everytime I used it. It was such a terrible experience and a loss of $100 because the "warranty" was to replace the product if I paid up to $20 in shipping fees! What a joke. So I took the chance to try a new brand and BOY AM I GLAD I DID! The set-up of this modem and counterpart router was so quick and easy and I immediately started have signals well over 100 mbps when I only paid for up to 50! Now I've increased my paid for speed to 100 mbps and I've ran tests on my router/modem just out of curiousity and it pulls up to 180 mbps at times! It's never below 50 mbps. The days of experiencing problems streaming media via firestick, phone, computer is over! I have 3 smart tvs, 2 firesticks, 3 laptops, 3 cell phones and numerous video games using wifi at any given time and I've never seen the modem/router even flinch. This product is a 180-degree turn from the comparable Arris product. I'm never using another manufacturer!

The modem arrived early, it worked perfectly after a call to COX, telling me to contact NETGEAR, because it was a modem issue is why it would not connect to my desktop or router. Netgear said it was my router, wrong. The next day a COX tech spent 4 hours at my home. He left telling me that I needed a new router and the internet to my desktop worked on some sites, did not work on other sites at all. For any COX internet customers, once you connect this modem, or any other brand, you HAVE to call the COX Sales department to have it activated, I repeat, call Sales. Also, I use Windows 10, you absolutely have to be logged in as the administrator, That is what I did, my desktop connected to the internet and I then connected the modem to my router and my desktop from the router and the modem has worked perfectly since then. I would buy from the Seller again, without a 2nd thought, I couldn't be any happier with their service. The modem has been an excellent buy and I am happy that I purchased it.

First off, it's worth noting that the product listing is incorrect when it says 200Mbps is the top speed this modem can do with Xfinity; looking at Xfinity's own list of compatible devices (see photo), this Netgear modem should top out around 370Mbps. I don't pay for that speed, but I can say definitively that it will do more than 200Mbps; in a speed test over my Nest mesh WiFi setup, I got nearly 220Mbps down, so coming right off the modem it was probably a bit quicker still.In terms of ease of use, I'd say this is about as easy as it gets with Xfinity right now (mid-2023). I hooked it up, did the activation dance, and presto there was internet.In any case, for those who have a good WiFi router/mesh system of their own, only pay for 200-350Mbps speeds, and don't want to pay extra for one of Xfinity's modem/router combo gateways every month, this fits the bill. My only gripe (and it's minor) is that this modem doesn't have a built in ethernet switch, and thus only has one ethernet port, but that's not surprising for a $50 modem.

This modem works great has been an awesome addition to our wifi system. The modem works as advertised. The problem with this modem is that there are only a few vents on the bottom. The modem gets extremely hot and shuts down. I had to buy fans to use with it so that it can cool down a little bit in the summer. If there were some holes in the sides with some mesh, to prevent dust from getting into the components, it would be much better.The overheating thing is not a huge deal to me because I can fix that. The real problem with buying anything from Netgear is customer support. Their customer support is absolute garbage! I hope that if you purchase a Netgear product that you will not need to call customer support. They do not know anything about their products. I can find more on Reddit than from Netgear. That being said, if you need help, search the internet before you call them. The internet knows more than Netgear does!
