Comporium: can you use your own modem?

Own modem allowed — approved list published

Yes — Comporium allows customer-owned modems and publishes its own approved-device list. It names devices including Customer Motorola SB8200 and Customer Netgear CM1000. Your device must meet at least DOCSIS 3.1. Buy from that list — anything off it may not activate. Every detail below is quoted from Comporium's own page, last checked 2026-08-25.

Your equipment has to satisfy Comporium before it reaches the internet at all — which is why their published rule, not a retailer's compatibility claim, is the one that decides.

Comporium names these models on its own page. They are the exact make and model strings published there as of 2026-08-25 — a sample of the list, not necessarily all of it.

Two boxes

One box — a “gateway”

  1. Modem + routerone unit does both jobs
Comporium treats the modem and the Wi-Fi router as separate questions. Read their wording below before assuming one box covers both.
