You should be able to set up more than one network using available ethernet ports on the extender, router, or switch. Download the Wavlink app from the Google Play Store for Android and from the Apple App Store for iOS. First, remove one of the light problems on the device. While attaching both wires, make sure the lights on the router also turn blue. When performing the Wavlink AC1200 setup, watch for the Wavlink mesh to also boot, connect both power and network cables, and have the light on your device lit blue. Install the app and verify it using your mobile device or laptop. When it gets installed, tap the button to launch it.
