Hi,
You can try to power off the camera, move it close to your router, power it on, wait for 10 minutes, and check if the LED on the camera will change.
If not, refer to the link below to reset the camera again and ensure the reset operation is correct.

If the problem remains, contact your retailer or local support to get a replacement if your camera is under warranty.

Best Regards
