What should I do if I fail to configure TP-Link Range Extender?

If you have already tried to configure the range extender but it failed, please check the following troubleshooting.

Some tips before troubleshooting:

1. If there is no RE light on some range extenders. It may have a Signal light or 2.4G/5G light. Please refer to the installation guide to check whether the extender is connected to the main network.
2. End-device means a computer, laptop, front-device(s) means your modem or main router, etc. which the TP-Link router is connected.
3. DFS Function: For Dual-Band Range Extender if there’s only a 2.4G LED light on, then 5G light off, please help fix the main router’s 5G to band1 (channel 36-48), then the RE should be able to connect to the Router in 5G.
4. Router Advanced Features: Check those main router functions that may have a bad influence on RE to connect and work stably:

Case 1: The RE light is off after the configuration

1. Check if the user enters the correct Wi-Fi password on the extender.
a. By forgetting Wi-Fi and reconnecting to the home Wi-Fi, enter the password again.
b. on iPhone, go to WLAN-> highlight the connected network name, and enter iPhone's password to see the password.

2. Put the range extender 2-3 meters away from the router. Factory reset it by pushing the reset button for a few seconds. And configure the range extender from scratch.

3. If possible, suggest giving a different name for 2.4G and 5G Wi-Fi on the Main router. It will help us to locate which band has a connection issue with the router.

4. If the RE light is finally on but still has no internet access, please go through and refer to Case Two or Three. If the RE light is still off, turn off and on the range extender and wait two to 2 minutes then check if the RE light will be lit.

5. Upgrade the range extender to the latest firmware and reconfigure it. Click here.

6. Make sure the main router doesn’t enable any security settings, like MAC Filtering or Access control. And Authentication Type and Encryption type are Auto on the router.

7. Try resetting the extender completely. Use a pin to press the button for 1 second to reset the extender. Also, once you reset, you need to reconfigure the extender following the FAQ:

8. Log into the range extender by using www.tplinkrepeater.net or the IP address assigned by the router (find the IP address from the router’s interface). Take picture of the Status page and save the system log (Save the log within 3-5 minutes after the range extender reboot).

Case 2: The RE light is on, and the end devices can not connect to the Wi-Fi of the range extender.

1. Check the wireless signal strength of the end devices. If only one end device cannot join the Wi-Fi of the range extender, remove the profile of the wireless network and connect it once again. And connect it to your router directly to see if it can connect.

2. If multiple devices cannot connect to the extender SSID, you may also follow the below link to see if can configure it well:

Case 3: The RE light is on, and the end devices can connect to the Wi-Fi of the range extender but have no network access.

1. Do not set the same SSID for the range extender and router. Otherwise, please reset the range extender and create a separate SSID.

2. Upgrade the range extender to the latest firmware and reconfigure it. Click How to upgrade the firmware of my range extender.

3. Try multiple end devices. If only one end device doesn’t have internet access, check whether the end device is obtaining an IP Address automatically. What if it connects to the main router directly?

4. Connect the same end device to the main router directly to check its internet connectivity. Check its IP address and Default Gateway when connected to the router and range extender. (click here)

5. Make sure the main router doesn’t enable any security settings, like MAC Filtering or Access control.

6. Log into the range extender by using www.tplinkrepeater.net or the IP address assigned by the router (find the IP address from the router’s interface). Take picture of the Status page and save the system log (Log taken within 3-5 minutes after the range extender reboot).

Note:

If the error message "No Host Network Connection" pops up after "the apply settings", it's probably because the router's 5G is using the DFS channel, please try to disable Band Steering on the router and change the 5G channel to Band 1(36, 40, 44, 48).
