• Move the router to a new location away from Bluetooth devices and other household
electronics, such as cordless phone, microwave, and baby monitor, etc., to minimize
signal interference.
• When in Range Extender mode, the ideal location to place the router is halfway
between your host AP and the Wi-Fi dead zone. If that is not possible, place the router
closer to your host AP to ensure stable performance.
