Shelby, IL Internet Speeds — Measured 2024
Real speed tests run in Shelby County, Illinois during 2024 recorded a median download of 18.2 Mbps, upload of 2.7 Mbps and latency of 18.1 ms, across 727 measurements. That is 0.2× the US median and places it #2,382 of 2,425 US counties.
What these numbers mean here
The median is the typical connection, not the best one available. Half the tests in Shelby came in below 18.2 Mbps and half above. The slower quarter of connections measured under 8.5 Mbps, while the faster quarter exceeded 61.0 Mbps — a spread that usually reflects a mix of fibre, cable and older DSL lines in the same area rather than one uniform service level.
At 18.2 Mbps down and 2.7 Mbps up, a typical household here can manage standard streaming and browsing, but will feel the limits with multiple users or large uploads. Latency of 18.1 ms is excellent for gaming and real-time calls.
