FROM MEASUREMENT TO A NEXT STEP
Make the next test more useful
A single number is a starting point. A controlled comparison helps you decide what to investigate.
Measure your connection
Pause large downloads. Test one device and note whether it uses Wi-Fi, Ethernet or mobile data.
Change one condition
Compare Ethernet and Wi-Fi, or repeat at a quieter time. Keep the device and test method the same.
Use the difference
Save the results. Follow the relevant guide or send a clear summary to your support team.
METHODS YOU CAN CHECK
Know what each result measures
The check above measures HTTP transfers and response timing between your browser and this site. It does not measure network packet loss. The dedicated speed test uses Measurement Lab NDT7. Results from different methods or destinations are not directly interchangeable.
Your device, Wi-Fi, other traffic, server location and server load can affect results. Public reports describe their own source, sample period and limitations.
