Questions about this test
What should AT&T Fiber speeds look like?
AT&T Fiber tiers are symmetrical (for example 300, 500, 1,000, 2,000 and 5,000 Mbps), so upload should roughly match download. A 1 Gig plan tests around 900–940 Mbps wired; multi-gig plans need a 2.5 Gbps or faster port to show more than ~940 Mbps.
Why does my AT&T gigabit test show only 940 Mbps?
A standard gigabit Ethernet port tops out at about 940 Mbps of usable throughput. That's the cable, not AT&T. Over Wi‑Fi, 600–900 Mbps is a good result.
AT&T Internet Air is slow — is that normal?
Internet Air is fixed wireless (5G), so speeds vary with signal and congestion, commonly 75–225 Mbps. Try moving the gateway near a window facing the tower.
Is this the official AT&T test?
No. gbps.run is independent and ad-free, and is not affiliated with any provider.
