Hi, 
If you forget the wireless password of your new router, please contact your router support team for assistance. The default SSID of the Tapo C100 is an open Wi-Fi that does not require a password to connect, and this Wi-Fi is used to search for the camera during configuration. It will disappear after the camera is configured.

In this case, you can try the following steps for troubleshooting:
  1. Press and hold the reset button on the camera for 10 seconds to factory reset it.
  2. Wait for two minutes, and when the camera has a flashing red and green light, you can refer to the following instructions to set it up: How to set up the Tapo camera 
  3. If you fail to set up the camera, please refer to the instructions to troubleshoot: What should I do if I fail to configure Tapo Camera? 

Best Regards
