Point-of-sale, cameras and guest Wi-Fi on one connection, with 5G backup on 1 GIG and up so the card reader keeps working.
Multi-location owners
One provider, one bill, one contact for every site that has fiber, and Internet Air for the ones that don’t yet.

Ookla named AT&T Fiber the fastest fixed network in the United States for the first half of 2026.
Honest limits
What we tell you before you order
- Fiber exists only where AT&T has built it (its wireline footprint covers 21 states and keeps expanding). The address check is the honest gate; we never assume.
- New construction to a building takes months. If you have a move-in date, we plan Internet Air as the day-one bridge.
- Business Fiber is a shared, best-effort service. If you need a bandwidth SLA and dedicated capacity, that’s AT&T Dedicated Internet, and we’ll say so.
