HOA Xfinity Fiber Community Upgrade Situation

I am looking for clarification and escalation regarding Xfinity service requirements in my HOA community, as I have been unable to get clear technical answers through normal support channels.

Our HOA has been under long term Comcast and Xfinity bulk agreements since we moved in. Historically, cable TV and internet service have been intermittent but manageable. For reliability, I have primarily relied on AT&T symmetrical fiber for my home network, which allowed me to tolerate periodic Xfinity disruptions.

Recently, our HOA transitioned to a fiber to the home deployment using an EPON and ONT setup. I have no objection to fiber delivery itself. However, I have now been told that Xfinity requires the use of an Xfinity provided gateway and that customer owned routing equipment or bridge mode is not supported in our community.

This is a major concern for me.

I am aware that Xfinity gateway equipment normally supports bridge mode and the ability to disable WiFi, and that many customers maintain their own internal networks using this configuration. Despite this, I am repeatedly being told, without any technical explanation, that our specific community does not support bridge mode or customer managed networking.

As a result, I am being told that I must either fully integrate into the Xfinity gateway ecosystem and abandon my existing network, or lose access to TV service entirely. That is not an acceptable choice.

To make matters worse, when I asked an on site technician to confirm whether I could keep my existing network intact, I was met with an unprofessional comment suggesting that if I was such an expert, I should work for Comcast. I mention this only to explain the level of frustration and lack of meaningful answers I have encountered.

At this point, I am not asking for special treatment. I am simply asking for clear and authoritative technical answers to the following questions:

1. Is it technically impossible in this EPON deployment to place the Xfinity gateway into bridge mode

2. If it is not possible, is this due to a technical limitation or a policy decision

3. Is there any supported configuration that allows customers to manage their own routing, firewall, and WiFi infrastructure

4. If not, is the expectation that customers pay for a service they cannot realistically use

I have made multiple attempts to get these questions answered and have only reached introductory call centers that are unable to escalate or provide definitive information.

I am requesting that someone with appropriate technical or engineering knowledge review this and provide a clear response. I am simply trying to determine whether I can continue using Xfinity services in my home without being forced to dismantle an existing, functioning network.

Thank you for your time.
