Hi,
Typically, if the camera is configured successfully via Wi-Fi, after connecting it to the router with an Ethernet cable, the wired connection will take effect immediately. For the reported phenomenon, please confirm the following information for analysis.
1. Is the camera wired and wireless to the same Wi-Fi router?
2. Please disconnect the Ethernet cable from the camera, connect it to a computer, and then test whether the computer has an internet connection. If yes, what's the IP address on it?
How to find IP address on your devices
3. When the camera is connected to the router's Wi-Fi, please go to its Device Settings > Device Info page to find the IP address.
Best Regards
