Hello  @Sid09 ,

Welcome to our community.

 

Please try the following steps for your case:
1. Power Supply Check: Ensure you are using the original power adapter that came with your router. Try plugging the router into a different power socket or outlet.
2. Firmware Update: Log in to your router's web interface by entering http://tplinkwifi.net in your browser. Go to Advanced > System > Firmware Update and check if there is a firmware update available. If so, update to the latest version.
3. Device Isolation Test: For troubleshooting, unplug all Ethernet cables from the router and change your Wi-Fi network name (SSID) to disconnect all wireless devices. Check whether the router continues to reboot. This helps determine if a connected device is the cause of the anomaly.

 

Have you enabled the MLO network? If yes, please disable it for a try.

 

If the suggestions above don't help, please contact local support for further help.
