Free Wi-Fi Test

Click the Start Wi-Fi Test button on this page. The tool sends a burst of 30 pings to the nearest server and analyzes the results for latency, jitter, and spike patterns. The entire test takes about 15 seconds and gives you a clear picture of your wireless connection quality.

Wi-Fi signal strength is measured in dBm (decibels relative to a milliwatt). A signal of -30 to -50 dBm is excellent, -50 to -60 dBm is good, -60 to -70 dBm is fair, and anything below -70 dBm is weak. You can check your signal strength in your device's Wi-Fi settings or network utility.

Use 5GHz when you are close to your router and need faster speeds for streaming or gaming. Use 2.4GHz when you are farther from the router or need to connect through walls and floors. 5GHz offers faster speeds but shorter range, while 2.4GHz provides better range but lower maximum speeds and more interference from other devices.

Frequent Wi-Fi disconnections are usually caused by signal interference, router overheating, outdated firmware, or too many connected devices. Try moving closer to your router, restarting the router, updating its firmware, or switching to a less congested Wi-Fi channel. Running this Wi-Fi test can help identify if the issue is related to latency spikes or connection instability.

Place your router in a central, elevated location away from walls and metal objects. Switch to the 5GHz band if you are within range. Update your router firmware to the latest version. Reduce interference by moving away from microwaves, baby monitors, and Bluetooth devices. Consider a mesh Wi-Fi system if your home has dead zones.

Jitter is the variation in latency between packets sent over your Wi-Fi connection. Low jitter (under 5ms) means your connection is consistent, which is important for video calls, gaming, and streaming. High jitter indicates that packets are arriving at inconsistent intervals, which can cause stuttering, buffering, and dropped connections.
