What Each Number Means

• Download (Mbps): how fast data comes to your device.
• Upload (Mbps): how fast your device sends data out.
• Ping (ms): delay/latency for round-trip communication.
• Jitter (ms): variation in latency over time.

Good streaming and browsing depend mostly on download. Calls, uploads, and cloud work depend heavily on upload and stability.

How to Run a Useful Test

For realistic results:

1. Test on Ethernet first, then on WiFi.
2. Stop big downloads/uploads during test.
3. Run at least two times: off-peak and evening peak.
4. Test from the room where issues happen.

A single test at noon can hide evening congestion.

Interpreting Results in Context

If download looks fine but calls still stutter, check upload, ping, and jitter. If numbers collapse only at peak hours, that suggests congestion or line consistency issues. If only WiFi tests are bad, local setup may be the issue.

A first-class connection should be not just fast on one test, but stable across normal usage windows.

Common Patterns and Next Steps

• Low download + low upload all day: plan or line limitation.
• Good off-peak, bad peak: likely congestion.
• Good wired, poor WiFi: in-home signal/setup issue.
• High jitter/packet-like symptoms: instability, even if speed looks okay.

If problems continue, compare results with symptoms like buffering or lag to isolate the cause.
