All settings must be the same on both devices. Ensure that the AP and the Wireless Access Point are not receiving radio signal interference and are within range. Move the devices closer together and away from any sources of interference, such as microwave ovens, Bluetooth devices and other radio transmitters. Restart OTIST on both devices.
