For your reference, here are some solutions you can try:
1. When any of the network-related settings are altered, such as Wi-Fi credentials or physical location changes, the camera will lose connectivity. Resetting the base station will clear previous settings, allowing for a fresh connection setup through the Mi Home/Xiaomi Home APP;
2. Try placing the base station as close to the router as possible to ensure network stability. Placing the base station close to the router minimizes signal interference and strengthens the connection between the camera and the network. This proximity helps in maintaining a stable and reliable network connection for uninterrupted camera operation.
