Wondering why you get low speeds on your WiFi Network? This is the app for you! WiFi SNR is a "Practical WiFi Analyzer" that helps you identify the WiFi performance at different locations in your home or office.


Signal-Strength is not the only reason for bad WiFi speeds, as popularly believed. Research indicates that WiFi speed (throughput) depends on Link Speed, Signal-to-Ratio (SNR) and Signal Strength. When a WiFi device (such as your laptop or iPad) is far away from your WiFi Router, the Signal-to-Noise Ratio and Signal–Strength decreases. As a result, your device auto-adjusts the Link Speed to a lower value in order to handle packet loss and interference.

This app provides WiFi Link Speed, Signal-to-Noise Ratio and Signal Strength of your WiFi connection. You can easily identify how your WiFi performance changes in different locations (at your home or office).
