new modem

I received an email stating that my current modem is no longer receiving important security updates and that I should purchase a new modem, specifically, a Netgear CM2500 or CM3000  or "a compatible device." Following the link, I learned that the suggested Netgear modems are not available, but I can find no other information that describes the specifications of alternative modems that might be comparable. What are the specs for the upgraded modem?

I also received this email. I'm currently running a Netgear C7100V.  My data speed is 800 Mbs although I only need ~300 Mbs or less.  They kept upgrading me.  The cable modems they linked to in the email, and you mentioned, do not support voice.  The xfinity device page shows a Netgear CM2050V as supporting voice.  Unfortunately, it does not support wifi.  I am curious to see their response to your post. 

Thanks for your post!!

user_4667vr We would be happy to review you account if you feel your speed is higher than your needs to see if we can find a better option for you, and possibly save some money. The CM2050V although not a gateway with built in router would still work, it just requires a seperate router connected to it as it is mainly just a modem.

Frustrating because now my wife is panicked that we are going to be hacked :( Really poor communication from Xfinity, in my opinion.

Give us notice, provide multiple options from various manufacturers, and include the exact specs needed and why they are needed.

Otherwise, it sounds like NetGear wanted some love, and Xfinity gave it to them.

user_2fjks6 We suggest going here (https://www.xfinity.com/support/internet/customerowned) to view the third-party modems that are compatible with us. Please let us know if you have any other questions.
