How does TP-Link Wi-Fi extender work?

A TP-Link Wi-Fi extender helps increase the range of your existing wireless network to eliminate dead zones and ensure stable connectivity throughout your home. It works by receiving the wireless signal from your router and rebroadcasting or “extending” it to areas that were previously out of range.

How does TP-Link Wi-Fi extender work?

TP-Link Wi-Fi extenders connect to your router wirelessly to avoid running long Ethernet cables. Once connected, the extender performs a site survey to determine the best location to rebroadcast the signal from. Strategic placement is key for optimal Wi-Fi extension.

When devices connect to the extender’s wireless network, requests are forwarded seamlessly back to the router using TP-Link’s Fast Roaming technology. This technology enables your devices to move between coverage areas of the extender and router without dropping the connection.

How to Set Up a TP-Link Wi-Fi Range Extender

Setting up a TP-Link Wi-Fi extender to boost your wireless coverage at home is quick and straightforward:

  1. Place the extender: Position it about halfway between your router and the Wi-Fi dead zone, within range of the host router network. The location should also have good reception from client devices.
  2. Connect the extender: Press the WPS button on the router and extender simultaneously if they have WPS capability. If not, connect with the network name and password of your host network instead. The extender will copy your wireless details.
  3. Check the connection: Wait for connection, indicated by a solid light on the extender. Perform a site survey with the TP-Link Tether app if needed to check the connection quality.
  4. Set up the extended network: Give your extender’s network a name and password. Keep it the same or add “EXT” to the SSID so devices auto-connect when in range.

Once set up, connect devices to the extender network when they are beyond your router’s range but within the boosted coverage area. Seamless roaming technology maintains the connection as you move between networks.
