Measure your real-time download and upload speeds, latency (ping), jitter, and overall connection quality for streaming, gaming, and remote work.
Run a speed test to inspect your connection health and fetch dynamic suggestions.
Compare your result against real-world requirements for common activities to see where your connection stands.
Evaluating connection quality goes far beyond download speed. Here are the core parameters that define your internet health:
The speed at which data travels from the internet to your device. Higher download speeds are required for streaming HD/4K videos, loading websites, and downloading large documents.
How fast your device sends files to the web. Critical when backup synchronization runs, during screen shares, video conferences, or uploading media.
The duration in milliseconds it takes for a data packet to travel to a destination server and return. Lower ping (under 30ms) is essential for online multiplayer games and fluid voice-over-IP calls.
The variance in ping responses. Unstable lines with high jitter (above 15ms) create packet delivery delays, causing voice crackles and video buffering.
If your speed test reports results lower than your service plan promises, try the following steps to identify local bottlenecks:
Wi-Fi signals weaken due to walls, distance, and interference from household devices. A physical LAN connection guarantees pure line speed.
Modems and routers accumulate cache logs and memory leaks. Restarting them forces the hardware to establish fresh, optimized carrier connections.
Background downloads, system updates, and automated cloud backups (Google Drive, iCloud) consume significant bandwidth during testing.
Virtual Private Networks encrypt data packets and route them through extra proxy servers, which increases ping times and often reduces throughput by 10-30%.
The speed test sends and receives chunks of binary data using HTTPS requests to measure the elapsed transfer time. It dynamically increases request sizes to saturate your bandwidth, providing an accurate, real-time calculation of your connection's throughput in Megabits per second (Mbps).
Download speed measures how fast data can travel from the internet to your device (important for streaming or browsing). Upload speed measures how fast data travels from your device to the internet (critical for video calls, backup uploads, and streaming games).
Ping (or latency) measures the reaction time of your connection, indicating how quickly your device receives a response after sending a request. It is measured in milliseconds (ms). Lower ping means a more responsive connection, which is crucial for real-time online gaming and live voice/video calls.
Jitter is the variation in latency over time. A highly unstable connection will experience high jitter, leading to buffering, audio distortion, or dropped frames during VoIP calls and gaming, even if the overall download speed is high.
Try moving closer to your Wi-Fi router, connecting via an Ethernet cable, pausing other active downloads/streaming on your network, restarting your modem/router, or closing background applications consuming bandwidth.
