[Action needed] Move your Xfinity service to your supported modem

I received an email (see below) from Xfinity today asking me to take action by removing an old cable modem on my account. There is no option to remove a cable modem on the website or Xfinity app. How do I resolve this?

email:

Switch to your supported modem today
You have more than one modem on your Xfinity account, including a supported modem that's ready to deliver a secure and reliable internet experience.
Your current modem is no longer receiving the latest security updates. Without the latest features, the security and performance of your modem may be impacted over time. Over time, this may affect your modem's security and performance. Move your Xfinity service from your older modem to your supported modem that's already on your account to help keep your connection secure and reliable.
No equipment purchase is required. Simply switch your supported modem to continue enjoying the latest Xfinity services and future network enhancements.

I received this email today as well, shortly after upgrading to a gigabit plan. A buddy of mine also received one. My current modem is under 2 years old and supports well over 1 Gbps, and the only other modem attached to my account is a 6+ year old junker that can't accommodate 1 Gbps, so the email itself made no sense. The whole "latest security updates" line is also sketchy and vague, so I started a chat and the agent couldn't give me any real answers. First they said my modem is no longer compatible, but I told them it's listed on Xfinity's compatibility page. Then they said it's compatible but can't handle gigabit speeds, so I pointed them to where it says on Xfinity's own site that it does. I also cited my own speed test results. Then they said the only problem is that the "modem boot file and firmware" require an update. I asked a couple of times what the email was referring to with the "security updates" but they just kept falling back to the "modem boot file and firmware."

My takeaway is that this email went out to a bunch of customers as a roundabout way of scaring them with the "security updates" language into renting a modem from Xfinity.

I was able to get the agent to remove my old modem from my account though, so it seems that's an option if you really want to go through the hassle.

I receved the same nonsensical email today. I've been using the same CM for years, and it is still in the approved HW list.

It looks like Comcast/Xfinity is trying to scare up some business to rent their modems.  I also got a couple of these email messages.  From the sound of things, it would be best to simply ignore these messages.

 I got the email. It is inexplicable. Why doesn't it explain how to remove the old modem from your account. Wasting my time. And they wonder why we hate them.

Doesn't anybody from Xfinity monitor these forums so they can answer questions like this?

The DOCSIS standard puts management of the CM in the hands of the ISP. At initialization, they check firmware version, update it if needed, and and send the configuration file.
