On August 3, 2024, I activated my new Arris S34 modem thru the Xfinity app.

This morning, I called Xfinity to ask, what’s my firmware update schedule.

Xfinity said, Arris is responsible for that.

Where do I go from here?

Thank you!

You don’t. There isn’t much for firmware changes on modems. Their firmware is tightly controlled by the ISP and rarely changes because any changes requires re-certification and costs a lot of $. So it rarely happens. 


DOCSIS standards dictate that the service provider must distribute firmware updates to cable modem devices.  The end-user cannot simply install an update like most other network-enabled devices.

ARRIS develops the software update and makes it available to service providers.  The service providers qualify, test, and distribute the software update to devices on their network.  ARRIS has limited control or visibility on distribution by the service providers.
