How to check if your wireless adapter has been installed correctly (for laptop users only)
To check if the antenna has been installed properly, make sure you have two (2) different wireless connections detected in your laptop. When you click the WiFi icon in your Windows taskbar, you should see two connections like the image attached.
It might not say WiFi 2 but there should be more than 1 available Wi-Fi connection. That means that the KUMA WIFI USB ADAPTER has been installed properly.
