What is WiFi Guardian?
WiFi Guardian is an Android utility for analyzing WiFi networks and reviewing devices connected to your local network. It combines wireless analysis, device discovery, network information and monitoring tools in one place, making it easier to understand WiFi conditions, identify connected devices and investigate common home network issues.
Analyze WiFi Channels and Signal Strength
Use the WiFi Analyzer to inspect nearby wireless networks, compare signal strength and review channel usage across supported WiFi bands. Channel and signal information can help you understand crowded wireless environments, weak coverage and interference, while placement and diagnostic tools provide additional information when evaluating your WiFi connection.
See Who Is Connected to Your WiFi
WiFi Guardian can scan your active private local network and show devices that are visible on the same WiFi connection. Review available information such as device names, local IP addresses, MAC addresses, estimated manufacturers and device types. Familiar devices can be marked as trusted, while unfamiliar or newly observed devices can be kept for review.
