Hello @yamang35 ,

Welcome to our community.

For your case, please try the following troubleshooting steps:
1. Plug the extender into a different power socket.
2. Try resetting the extender:
• Locate the reset pinhole on your extender.
• Press and hold the reset button until all the lights turn on for one second and then turn off.

Note: If you are using models such as RE220 V3, RE200 V5, or RE190 V5 and the extender keeps rebooting even after trying the above steps, please refer to this community post for further suggestions: RE220/RE200/RE190 Keeps Restarting Automatically
