• Scan finds Wi-Fi routers in your environment and gathers key details about them.
  
• Performance uses live graphs to show the performance of your Wi-Fi connection:
  • Rate shows the transmit rate over time in megabits per second.
  • Quality shows the signal-to-noise ratio over time. When the quality is too low, your device disconnects from the Wi-Fi router. Factors that affect quality include the distance between your device and the router, and objects such as walls that impede the signal from your router. Learn more.
  • Signal shows both signal (RSSI) and noise measurements over time. You want RSSI to be high and noise to be low, so the bigger the gap between RSSI and noise, the better.
