CM700 end of life?
I have recently had connection issues with Xfinity and they keep asking about my router (CM700) and they tried telling me today it was at "end of life". Is this true? last time they came out they...
Apologies, I am using the Cm700 connected to an ASUS router, RT-AX1800S. A few months back I started having intermittent Internet dropouts, at the time Xfinity had noted a high signal to noise ratio, determined it was a bad node, replaced it, and everything was good for a while. A tree hit the lines recently, they repaired the lines, I was having Internet issues again, and now they’re telling me that it’s because of the DOCIS 3.0 protocol that my older modem is using.
And for what it’s worth, that was my fault where I said router, I meant to say modem, and they knew it was a modem. I’m still not entirely sure they know what they’re talking about, but the modem/router confusion. There was my fault.

Cable technologies and standards do change. But without an explanation fro your ISP it does sound like they are passing the buck.
Have they phased out DOCIS 3.0?
I would still put some effort into troubleshooting the issue.
We still don't know what your "connection issues" are.
Disclaimer: Just another user with time on their hands.
- I don’t know how to answer your question about what my connection issues are beyond saying I had intermittent dropping of connection and high signal to noise ratio. Is there something specific beyond those that you are looking for? I will do my best to get that for you. I did see high numbers of errors on the modem side prior to them replacing “the node” they claimed was malfunctioning but I haven’t checked in this most recent incident.
Also I’m not sure if they’re phasing out 3.0 but it sort of sounded like that what the phone rep was getting at, yet my modem is still listed on their website as compatible as well as netgears website.Please post a copy and paste of the modems connection status and event log page.

Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.
What is the brand and model of the host wifi router connected to the modem?
The CM700 is still listed on the official Xfinity list of COAM (Customer Owned And Mainted) compatible devices. The list is dated September 18, 2024. Read the wording carefully at the top of the last table.
Here is the link: https://assets.xfinity.com/assets/dotcom/projects/cix-4997_compatible-devices/2024.09.18%20Full%20List%20of%20Compatible%20Devices.pdf
Whether you just bought it or not, the device design is getting old and it is one generation (DOCSIS 3.0 vs 3.1) behind. Vendors seldom pull items off the shelf just because it is getting old.
Not sure who you were talking to at Xfinity, they were trying to manipulate you to avoid a service call.
- Thanks for that list, guess I can’t say that xfinity didn’t put the info SOMEWHERE. I found a different list by them that didn’t mention the CM700 at all, but it was a list of only currently incompatible modems. This shines a bit more light on things. Guess it’s time to upgrade. Might as well get a 4.0 and be future ready.
But any reason why the phone tech would want to prevent a service call tho? I don’t see how it would benefit them in any way. Not saying I agree or disagree, just can’t understand why they’d care one way or the other.

It seems like support is reluctant to schedule truck rolls. It may be more prevalent in different parts of the country due to staffing. When they do get scheduled, often they are cancelled before they actually happen. Locally when they do happen, the Comcast tech visits are accomplished with contractors and not by actual Comcast employees. Also support always threatens a $100 truck roll charge if the problem is the fault of the customer and not the fault of Comcast. Kind of throws a bucket of cold water on the situation.
