What speed test numbers mean
Download speed shows how quickly data arrives. Upload speed shows how quickly data leaves your device. Latency shows how long a small request takes to make a round trip. All three affect real browsing, calls, uploads, and streaming.
Why results change
- Wi-Fi strength and interference.
- Other devices using the same connection.
- Browser limits and background tabs.
- Distance to the test server.
- ISP congestion and time of day.
Good testing habits
Run several tests at different times, compare Wi-Fi with wired if possible, and close heavy downloads before testing. If the result is much lower than expected, restart network equipment and test again before raising a support ticket.
FAQ
Why is upload slower than download?
Many home plans are asymmetric, meaning upload is intentionally lower than download.
Does one test prove my ISP is wrong?
No. Use multiple tests and check your local network before drawing conclusions.
