Wi-Fi Analyzer by Kevin Yuan (developed via ) is a highly popular Android application used to diagnose and optimize wireless networks. It provides a graphical representation of the Wi-Fi environment to help you identify interference and find the best channel for your router. Key Features Visual Graphs

Finding Optimal Router Placement: It allows for testing different locations for a router or access point to ensure maximum coverage, especially through walls or across multiple floors.

4. Security Auditing The app identifies the security protocol of every network in range. If you see a rogue access point pretending to be your router (an Evil Twin attack), the analyzer will flag it because the BSSID (MAC address) won’t match.

Signal Metering: It includes a "signal meter" (looking like a car speedometer) that tracks the dBm (signal strength) of a specific SSID in real-time, helping you find "dead zones" in your home .
