Easy to install. Works as advertised.
If you have Xfinity, if you have a phone or tablet connected to the internet through 4g or 5g, you can ignore the instructions in the quick start guide telling you to connect a laptop to the modem to activate the modem. You only need to do this if you have no other way to connect to the internet. Before you disconnect your old modem and router, download the Xfinity app from the app store onto your mobile device. Then, turn Wi-Fi off your mobile device, and proceed to disconnect your old modem and router. Navigate through the Xfinity app to add a device or replace your equipment. Follow-the instructions and your new modem will be "activated" to your Xfinity account.

Worth it if Renting Modem from ISP and looking for Improved Speeds
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.

CM1200 Provides Intermittent Signal - Inconsistent Mpbs, Mostly < 100 Mbps & Frequent < 50 Mpbs
I purchased the CM1200 in August 2020 and received it 8/8/2020. I attempted to connect the device at home as it was replacing the CM500. I have an AC1750 Netgear router that was connected to the CM500 and is now connected to the CM1200. I spent 5 hours the first night working with Netgear and my ISP (Comcast) to setup the device correctly; I was unable to use the activate link and had to call Comcast. While on the phone, Comcast stated because it's a Netgear product, Netgear would have to provide the firmware. However, Netgear's knowledge base states Comcast actually pushes the firmware. It started to feel like I was in the middle between Comcast and Netgear. This should have been an easy experience - plug and play - just like I have done with many other computer hardware.Once the device was setup, it worked well for about a week. The following Sunday I contacted Comcast again because I no longer was getting internet service. Comcast could not see the modem. We went through normal troubleshooting of a power cycle of both the modem and router. Internet service resumed. A little later, Comcast could not see the modem again. Went through the same steps and it was back.Comcast sent a technician out on 8/18/2020. They changed connections outside of my place. Also pushed all the service to one cable connection in my place; all other cable wall outlets do not have cable as I'm trying to ensure all the service is going to where I am connecting my internet and TV (I've been in this place for 4 years and did not have this problem previously until recently).The following Sunday I contacted Comcast again and went through the same steps. The following days I had to restart my modem each morning because I no longer had wifi when I got up to start work. I contacted Comcast 8/27/2020 to further discuss the issue. The first time we went through the normal steps of trying to restart the modem, unplug the modem, attempt to make a connection from Comcast to the modem, etc. Internet service came back... for an hour. An hour later I contacted Comcast again and they pointed me to Netgear. Now I really feel like I'm between Comcast and Netgear and no one taking ownership of the problem.After speaking with Comcast on 8/27/2020, I entered a support case with Netgear. I contacted them on 8/28/2020 because Netgear apparently does not reach out when a case is entered, it is up to the user to contact them after creating a case online. At 4 PM on 8/28, the Netgear technician had me reset the modem, unplug the modem, unplug the router and then reconnect everything. I explained I do this on a daily basis, but went along. When this was done, internet service returned... as expected. The tech said to monitor the internet for the next couple days to see if the problem persists. I told him I know what's going to happen and that I will be contacting Netgear again before a couple days ends. I asked if they could just send a replacement because I've been dealing with this issue for 3 weeks at this point, and he said just monitor the internet service.At 8 PM on 8/28 (4 hours after reaching Netgear) I was on the phone again with Comcast because internet service was non-existent. At 8:30 PM I began my hour long hold with Netgear following up on my open case stating what I told the prior technician that I would be calling Netgear back because I would no longer have internet service. We went through similar steps, however this time the technician had me change a setting on the router.I'm expecting I'll once again be contacting Comcast and Netflix on either 8/29 or 8/30 because the internet is no longer working for me.At this point, I'm caught between Comcast stating that I'm using my own device and they can't support that, and Netgear saying I have 90 days on my service warranty. Meanwhile, I have intermittent internet issues causing me to use my mobile hotspot to work.I will say Netgear tech support has been pleasant once I get through the queue, but I've been on hold 30 to 60 minutes each time I call and then another 30 to 60 minutes troubleshooting. I've also had to repeat many details along the way when I call, however, so that's frustrating.I'm hoping this gets resolved, or I'll have to work with Amazon to return the modem and hopefully get a full refund.

Activated on xfinity and wifi router connected is working but unexpected issue
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.

CM2500 works great with Xfinity and work VPN
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.
