Measured speeds are wired-test ranges observed across consumer plans; actual figures depend on plan tier, address, and time of day.

Speed Test Tips

• Test on Ethernet for a true line speed reading — not Wi-Fi
• Run tests at both off-peak (morning) and peak (evening 7–10 PM) times
• Check upload speed separately — it's the bottleneck for video calls and remote work
• If your measured speed is consistently under 80% of your plan speed, contact your ISP
