Test your internet connection stability with our free network latency checker. This test measures connection quality by sending 30 test packets to our server and analyzing response times. View detailed statistics including minimum, maximum, median, and average latency, plus jitter, packet loss, and connection reliability metrics.
A connection stability test measures the quality and reliability of your internet connection.
Latency is the time it takes for data to travel from your device to our server and back, measured in milliseconds (ms). Lower is better. We measure minimum, maximum, median, and average latency to give you a complete picture of your connection's responsiveness.
Jitter measures latency variation - how much your request time fluctuates between packets. Consistent low latency is ideal. High jitter causes stuttering in games, choppy video calls, and interrupted VoIP conversations. Jitter under 10ms is excellent, while values over 30ms indicate connection instability.
Packet loss occurs when data packets fail to reach their destination. Even small amounts of packet loss (1-2%) can severely impact real-time applications. Video calls freeze, games lag unpredictably, and downloads slow down. Zero packet loss is ideal. Any packet loss above 1% indicates network problems requiring attention.
Standard deviation measures consistency. Low standard deviation means your connection performs predictably. High standard deviation indicates erratic behavior with frequent spikes in latency. This metric helps identify network congestion, interference, or routing problems.
Under 5ms jitter with 0% loss is solid for video calls and gaming. Loss above 1-2% will cause noticeable stutter in real-time apps even if your raw speed test looks fine. That's the gap this test is designed to catch.
HTTP latency includes multiple components: DNS lookup time (resolving the domain name to an IP address), TCP connection time (establishing the network connection), TLS handshake time (securing the connection), and server processing time (the server generating a response). To provide accurate measurements, this tool runs 5 warmup requests before testing begins. These warmup requests establish the connection, complete DNS resolution, and negotiate TLS encryption - eliminating cold-start overhead from your results. After warmup, the tool runs 30 consecutive tests measuring your sustained connection performance. This approach ensures results represent typical browsing performance where connections are already established, not the slower initial page load. The warmup phase is critical for accurate testing since the first request to any server is always slower than subsequent requests due to connection establishment overhead.
Contact your internet service provider if you consistently experience:
Run this stability test multiple times at different hours to establish a pattern before contacting support. Document your results to provide concrete evidence of connection problems.
Competitive gaming: 50ms with minimal jitter and zero packet loss. Fighting games: under 20ms for responsive controls. High jitter causes rubber-banding and teleporting enemies.
Video calls: under 150ms but perform best under 100ms.
Streaming video is less sensitive to latency but requires stable bandwidth without packet loss.
Remote desktop: under 100ms.
Ping tests measure connection quality (latency and stability) while speed tests measure bandwidth (how much data transfers per second). You can have fast speeds but poor stability. Both metrics matter - speed affects download times while stability affects real-time application performance.
Network congestion varies by time of day. Peak evening hours (7-11 PM) show higher latency as neighbors stream video and game simultaneously. Your ISP's network experiences varying load. Additionally, internet backbone routes may change based on traffic patterns.
