Understanding Your Results
Download speed: How fast data arrives. 30+ Mbps is good for HD streaming, 100+ Mbps for 4K and multiple devices.
Upload speed: How fast you send data. 10+ Mbps is good for video calls and uploading files.
Ping/Latency: Response time. Under 20ms is excellent for gaming, under 50ms is fine for most uses.
Jitter: Variation in ping. Lower is better. High jitter causes stuttering in video calls.
