It contains the following sections:
Plug the extender into an electrical outlet next to your router, and then wait until the Power LED turns solid on.
Notes:
1.For safety, only plug the extender in upright direction as shown below.
2.The operating temperature should be between 0°C and 40°C (32°F - 104°F).
There are three ways to set up the extender: via the WPS button, via the TP-Link Tether app, or via a web browser.

.
1.Press the WPS button on your host router, and then press the WPS button on the extender for 1 second within 2 minutes.
Note:
For more information about using WPS button on your host router, please refer to the router manufacturer’s user guide.
2.Wait until the WPS LED 
changes to solid on, and wait until the signal LED 
turns solid on, which indicates that the WPS connection is successful.
Note:
If the LED does not turn solid on, try again or refer to Method 2: Via the TP-Link Tether App or Method 3: Via a Web Browser.
3.(Optional) If the extender connects to a dual band router, repeat steps 1 and 2 above to connect to the other band.
4.Relocate your extender for optimal Wi-Fi coverage and performance.
1 )Plug in the extender about halfway between your router and the Wi-Fi dead zone. The location you choose must be within the range of your router.
2 )Wait for about 2 minutes until the Signal LED turns solid blue. If it doesn’t, relocate the extender closer to the router to achieve better signal quality.
Tip:
To minimize signal interference, please choose a location which is far away from Bluetooth devices and other household electronic devices, such as cordless phones, microwave ovens and baby monitors.
5.Enjoy! Connect to the extended network and enjoy the internet.
Tips:
1.If you cannot find the network names with _EXT in your Wi-Fi network list, this means that the extender has been connected to a OneMesh router and automatically copied its wireless settings. For more information, refer to OneMesh with Seamless Roaming.
2.For some early firmware versions, the extender share the same network name as your router.
3.If you want to customize the extended network name, refer to To change the wireless network name (SSID).
