Own modem allowed — approved list published

Yes — Comporium allows customer-owned modems and publishes its own approved-device list. It names devices including Motorola SB8200 and 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.

  3. The internetthe part you actually want
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.

Can I use my own modem with Comporium?

Yes, with a restriction: the device has to appear on Comporium's published approved list. In their words: "However, you may purchase your own cable modem, provided it is DOCSIS 3.1 compliant to be compatible with the speed packages offered to our subscribers." See the modems Comporium approves.

What DOCSIS version does Comporium require?

"DOCSIS 3.1 compliant". Compare the DOCSIS version all 37 providers name.

Do Comporium's requirements change with my speed tier?

"provided it is DOCSIS 3.1 compliant to be compatible with the speed packages offered to our subscribers" — no per-tier breakdown is published on the page. See the modems Comporium approves.

Can I use my own router with Comporium?

Not stated as a policy. Inferable only from the list itself: the approved third-party entry "Customer Netgear C7800" is a modem+router gateway, so combo units appear on the permitted list. The page says nothing explicit about routers.

Comporium treats the modem and the Wi-Fi router as separate questions. Read their router answer before assuming one box covers both.Their router answer, above
