Dallas is AT&T's hometown, and it shows: fiber is widely available alongside strong cable and 5G options. Competition is healthy, so most residents can get a fast connection if they choose well.
What the Public Data Says
City-level speeds vary by provider and technology more than by any single average. For how Dallas compares nationally, the Ookla Speedtest Global Index and BroadbandNow publish metro-level availability and speed data, and the FCC's Measuring Broadband America program tracks real-world US broadband performance. These are more reliable than any single test for comparing neighborhoods.

Then compare your result with your plan's advertised speed. If it's consistently well below, read why your speed is lower than your plan and work through our slow internet guide before you call your provider.
