What this site will and won't claim

Sourced

Every gateway fact comes from an ISP support page, manual or ISP-moderated post, linked with the retrieval date. Third-party forum advice is not used as evidence.

Honest about gaps

39 gateways are researched so far; 2 of those end as "unverified" because the ISP's own pages did not settle it. 83 more models are queued, not guessed.

Open data

The whole dataset, including modems the ISP lists as approved, downloads as CSV and JSON. Get the data. Last review: October 26, 2026.

Approved modems

ISPs publish lists of modems they approve for customer-owned equipment. We only record what an ISP's own list shows. See what is listed so far (6 modems recorded; some ISP lists could not be retrieved yet and are marked as such).
