Welcome to the dedicated AT&T Speed Test tool. AT&T Fiber delivers 100% pure optical fiber-to-the-home connections with symmetrical upload and download speeds up to 5 Gbps (5000 Mbps). AT&T also provides AT&T Internet Air (5G Fixed Wireless) for wireless home internet. Run our test to verify your connection speed, latency, and stability.
Unlike traditional cable internet, AT&T Fiber offers equal download and upload speeds across its 300 Mbps, 500 Mbps, 1 Gig, 2 Gig, and 5 Gig tiers. A test on the 1000 Mbps plan should show ~940 Mbps in both directions over Gigabit Ethernet. This symmetrical throughput makes AT&T Fiber one of the best connections for creators, streamers, and remote workers.
AT&T Internet Air uses mid-band 5G spectrum (C-Band) to deliver home internet where fiber is unavailable. Typical speeds range between 75 Mbps and 225 Mbps. Performance depends on signal strength and tower placement. Position your AT&T All-Fi Hub near an upper-floor window facing the nearest cell tower for optimal performance.
If your AT&T Fiber speed test drops below expectations, check the Smart Home Manager app for line diagnostics. Ensure your BGW320 gateway has clean ventilation and test with an Ethernet cable to rule out local Wi-Fi channel interference.
Simply click the 'Start Test' button on this page. The tool will automatically measure your ping, download speed, and upload speed for your AT&T connection.
Compare your test results with the plan you purchased from AT&T. If your results are consistently much lower than your advertised plan, try restarting your router, connecting via Ethernet, or contacting AT&T customer support.
