Comcast business supplied modem EOL by Cisco back in 2017.

Comcast Buisness Class has a list of approved cable modems at https://business.comcast.com/help-and-support/internet/comcast-business-cable-modem-device-compatibi....

 

Today a technician replaced my old cable modem with a new (for negative values of current models) Cisco DPC3941B.

 

Cisco has this is as discontinued device (https://www.cisco.com/c/en/us/obsolete/video/cisco-dpc3941-wireless-residential-gateway-with-digital... with a content date of 25 June 2017). That means no updates to the firmware from Cisco. Does Comcast support leaving insecure devices on their network?

 

Should I decide on dropping the overpriced leased equipment is there any bonding of signaling, or specific configurations  that is done by Comcast on leased modems that could be done on a customer supplied cable modem to improve bandwidth perfomance.

Re: Comcast business supplied modem EOL by Cisco back in 2017.

Thank you so much for taking the time to reach out to us through our business forums. The DPC3941B is not an end of life modem for business internet services. The end of life status that you are referencing is that it is no longer a modem that will support our residential phone services. As a business customer your modem is only supplying an internet connection and if you have business voice services with us you have an entirely different modem for that purpose. If you would like me to review the services further I am more than happy to do so. Please reach out through private message with the name, address and phone number on the business account and I can address any further service concerns.
