The Tp-Link extender takes the wireless signal from the router and retransmits it to the dead zone areas. The main advantage of using a TP-Link extender is the wireless setup. You have to keep in mind that the extender position matters a lot. Choose the right location for your Tplink extender. Place the TP-Link device at a central place and closer to your current router. Place the device away from any electronic devices such as a cordless phone, microwave, etc. After you place the extender, you have to set it up by using the tplinkextender.net or tplinkrepeater.net.
