ONT modem

1 year ago (May 13, 2025 to be exact) Xfinity connected my newly built home with fiber. I was set up with an ONT modem (The Nokia NKFN11AEL model 3FE48103AAAA) to be exact.

It then runs to the classic Xfinity white tower router. I was hoping to just have one unit, even it is a self purchase. I can NOT find anyone at Xfinity to tell me if there is a combo unit i can change to.

Dont get me wrong, this setup works. But, the router is too bulky to fit in my network panel.

1. Is there a combo unit that i can use?

2. Will "ANY" router work with the set up i currently have

Nope. Their gateway device must be used with their ONT. They use the (DPoE) Docsis Provisioning over Ethernet protocol within it for management and authentication purposes. Google for more info.

Thanks for reaching out @Zupus! Our Fiber to the Premise (FTTP) technology with an Ethernet Passive Optional Network (EPON) uses an Xfinity Fiber ONT paired with an Xfinity Gateway. I completely understand why having two devices (especially with space constraints) isn’t ideal.

Is there a combo unit you can switch to?
- At this time, there isn’t a single combo device that replaces both the fiber ONT and the Xfinity Gateway. The ONT is required to terminate the fiber connection, and the gateway is used for authentication and service provisioning. With Xfinity Fiber, those functions can’t be combined into one customer‑owned device.

Will any router work with your current setup?
- As EG mentioned, the Gateway must be used with the ONT. Customer owned devices are not supported at this time.
