How do I find my AC750 Range Extender's IP address?

Log in to your router by entering http://www.routerlogin.net in your browser and entering your router's admin username (usually 'admin') and password. Select 'Attached Devices' to view a list of all connected devices. Find your extender in the list and note its IP address. This is useful if your extender and router use the same WiFi network name and you need to access the extender from an Android device.
