Optimal placement of your Dlink extender plays a vital role in transmitting a good amount of Wi-fi signals into your router. Users are recommended to place the extender in the midway of the router and the dead spot area where they are unable to catch the Wi-fi signals. A user can also use the signal LED of his range extender to find a good spot to place his dlinkap.local extender device. Once the signal LED turns solid green or amber, it means your extender finds an optimal spot to transmit a good amount of Wi-fi signals into your router.
