Customer-owned DOCSIS 3.1 modem capped at 200 Mbps on a 1 Gig plan

Today I activated a customer-owned DOCSIS 3.1 modem, the Hitron CODA56, which is specifically recommended on Xfinity Device Info page for my service. The modem is online, but I’m capped at ~200 Mbps download. I’m on a 1 Gig plan.


Chat and IVR, which are not helpful, will NOT allow Agent. I need the modem reprovisioned and the correct bootfile pushed, as my new CODA56 has been provisioned to wrong 200 Mbps bootfile on 1G plan despite activation and repeated resets. Thanks.

jzsmart3 Thanks for creating a post. Have you also tried to run the internet troubleshooting diagnostics through the Xfinity app? I ask since it will automatically check and provision the equipment as well. Our team is of course here to help if needed as well. If you still need assistance, please send our team a direct message with your full name and address.
