Hello @Pipi06 ,

Welcome to our community.

According to Google Translate, your question is the RE200 failed to reconnect to the network with abnormal LED. If there is any discrepancy, please describe it in English.

Thanks for reaching out. I understand that after a recent power outage, your Range Extender stopped working, the power light is blinking, and all lights occasionally come on, but you can't reconnect to your home Wi-Fi.

Here are some troubleshooting steps you can try:
1. Restart both your router and the Range Extender.
2. Make sure your router's Wi-Fi network is working properly.
3. Confirm that your Range Extender is within range of your router.
4. Keep the extender away from devices that may cause interference, such as metal objects, fish tanks, microwaves, and Bluetooth devices.
5. Restore the extender to factory default settings:
• Use a pin to press and hold the reset hole for 1-8 seconds.
• All lights will turn on momentarily when the extender resets.
• After resetting, launch the Tether App and click the top right '+' button to add your extender again.
