Best speeds: Fiber connections in metro areas—consistent performance with symmetric upload and download

Rural speeds: DSL or fixed wireless typically deliver 25–100 Mbps; satellite (Starlink) is an option where wired service is unavailable

Speed Test Tips for Maryland Residents

Test on Ethernet to measure your true connection speed, not Wi-Fi overhead
Run tests at both off-peak (morning) and peak (evening 7–10 PM) times—cable networks often show 20–40% lower speeds at peak hours
Check upload speed separately—upload is the bottleneck for video calls and cloud uploads, not just download
If your measured speed is consistently below 80% of your plan speed, contact your ISP or check for modem/router firmware updates
