Super easy to set up through Cox, fantastic speeds and a great interface. Hasn't dropped my connection yet. Works great with my RS300 Wifi7 router, also from the Netgear Nighthawk line.

I've had the CM2500 for about three months and it's working great with Xfinity 600Mbps service. It actually solved a problem with my work VPN and dropping issues (via HP/Aruba device). Starting around Dec 2024 my work VPN would drop about every 5 mins, happening about every day (was using a Motorola DOCSIS 3.0 modem). I tried the Hitron CODA56 modem (DOCSIS 3.1) and same problem. With this modem no VPN drops since installing and overall connectivity has been very reliable.

Bought this modem 5/10/25, Open box item, very easy install using the Xfinity app on phone, Up and running already 718Mbps download, 40mbps upload, seams like everything is working good so far, Thanks for the awesome deal Amazon!

I have had issues with my Nighthawk router & modem since day one. My internet will just drop out of nowhere and my wifi signal is crap despite the fact that I live in a tiny studio apartment. It goes through phases of how bad this will get but at its worst it'll happen multiple times a day. I have to wait several minutes to half an hour and then it'll eventually come back. I work from home and do live streaming, conference calls, etc. as so many of us do nowadays, so you can imagine how bad it is to have an internet that randomly drops out and cannot be brought back manually (turning off/on or unplugging doesn't work, I literally just have to wait it out) is for me and I'm sure so many others. The wifi even when available is always sluggish and unreliable despite me having a faster-than-necessary internet plan and, again, living in a tiny apartment (I sit mere feet from my router/modem). Although I did a ton of research, I wish I had actually looked up Netgear on the Better Business Bureau (not that we should have to go that far as consumers). If I had, and I recommend you do before purchasing, you would see a) that they have a 1 out of 5 star rating, and b) that the router dropping internet/wifi is an extremely common issue that they are well aware of and yet they keep selling these expensive faulty pieces of equipment anyway, making it as much of a hassle to get a refund as humanly possible. Seriously: DO NOT BUY. I got the Asurion protection plan and when I first called to file a claim, they said I had to wait until my internet dropped AGAIN to call back and then they would file the claim. So, I had to wait until it dropped during business hours to call back and quickly realized this was a total scam to make me wait to file a claim. On top of that, they are only refunding the cost before tax, and are only refunding me for the router, the modem is supposedly on a "different" type of plan where they have to service it first to see if anything is wrong with it, which tells me they know the router is messed up. I don't know if anything is wrong with the modem, so I may be stuck with a modem I don't need and can't use (I have given up and just gotten a modem/router from my internet provider, hoping then at least they'll have to provide me with some level of tech support!), making the money I spent on that a complete waste. It makes me sick to think of the headaches I've had with this equipment and how hundreds of my much-needed dollars are going to be wasted by this scam. On top of all of this. the protection plan just gives you an Amazon gift card, you don't even get your #%$&@!^ money back. If you do buy this, make sure to return it within the window at the first sign of ANY problem. I was convinced it was a problem with my service provider because, certainly, this crazy-expensive equipment I just bought couldn't be the issue. By the time I realized it was, it was too late and I thought I was fine because I had these protection plans. But the protection plan is a total ripoff and will not fully protect you even if it is obvious and provable that the equipment is faulty. I cannot stress enough to not buy any of this garbage. Unfortunately, I don't know what might be better, I hear a lot of the older routers are more reliable and still work well, but as we move to faster speeds we seem to be in a wasteland of crap equipment and b.s. support.

I activated this modem on my existing xfinity account fairly easily with the xfinity android phone app and xfinity account login. The fast TP-Link wifi router I connected to it is working great and much faster than the xfinity wifi. I first set up the wifi router using the xfinity modem and it worked that way too. I noticed later that on the box it says that the xfinity speed supported for this modem is only 800mbps, but the xfinity compatible routers page states that this modem supports 1Gbps xfinity speed. The unexpected issue is that anything else I have plugged in to the other ethernet ports on the modem do not get an internet connection. The main wifi router connection does work though and the port lights up green on the modem but the other devices light up amber (the other devices do work connected to the wifi router ethernet ports). Tech support and documentation say that an amber light means it is a 10 or 100 mbps connection. Tech support rep said the connection "should work" but nothing will connect to the internet if the light is amber for that ethernet port on the modem(she is wrong, it is not a router or multi lan connect device). Documentation does not say either way but diagram on box shows picture of router, computer, or "compatible routers" connected to the ethernet ports, but nothing is explicitly stated. My computer did connect to the modem's ethernet port and got access to the admin setting page for the modem, but even a second brand new wifi router I have would not get a green light or internet connection, and a Roku ultra didn't work (would not connect to internet). Other than that, and no clear info in documentation on the ports issue, features or specifications, the modem works as indicated, but it is basically working as a 1 port modem with the option of technical set up using the other ports for a single port function. Again, it is a modem with no router functionality, i.e. no multi-port lan connect functionality. Just a side note that nothing on my xfinity accounts billing has updated after the netgear modem activation and there is nothing on my xfinity account to return the xfinity modem so I will have to call them to remove the $15/mo for that and an appointment or return code to return it to them. Update: I called them and they essentially just did a new service plan without the modem, but with the other discounts for the 1 year contract renewal. There was no return code or anything provided, she just said to take the modem and power cord to UPS, they scan the bar code on it box it and return it to xfinity per their agreement with comcast and I did that. It takes "up to 2 weeks" for them to receive it, process it and remove it from your account billing - it was 2 days in my case.

Actually did improve my internet speeds compared to the modem provided by my ISP. Makes my internet bill cheaper also because I’m not renting one from ISP. Make sure it will work with your ISP before purchasing, if it does I would recommend.
