Hi@PTW_7,

 

Welcome to our community.

 

If your router is having self-rebooting issues, please try the suggestions below: 
1. Make sure the original power adapter is used, try another power socket/outlet.
2. Update the firmware of the Router to the latest one. Please refer to How to upgrade the firmware on the TP-Link Wi-Fi Routers
3. Unplug all Ethernet cables attached to the Router, change the Wi-Fi network name into another one to disconnect all wireless client devices, see if the self-rebooting issue disappears.


If the above troubleshooting steps are not helpful, please contact local TP-Link support for further assistance.
