If you’re using an Android device, you can check the WiFi Ghz speed by going to Settings and selecting Wi-Fi. If the WiFi Ghz speed is lower than your desired speed, you can try increasing it by following these steps:

  1. Open the Settings app and select Wi-Fi.
  2. Scroll down to the bottom of the Wi-Fi section and select Speedtest.net.
  3. Enter your desired WiFi Ghz speed in the Speedtest.net window and hit OK. The WiFi Ghz speed will be displayed in meters on the left side of the window.
