Many Android Apps only have two network modes: data and WiFi in their logic. They are available but will not connect to the Internet if they detect that they are not connected. You can encapsulate the framework layer into a WiFi interface (the method of not implementing WiFi only leaves the interface), and then you can connect to the iface layer however you want; or you can turn on the WiFi connection or data connection but iptables is directed to the Ethernet iface (in simple terms It’s all deception).

Not sure about the following points:
The browser can access the Internet. Do you mean the browser on the tablet? Or a browser on a PC.
LinkWifi App No problem means that the App on the tablet can connect to Wifi?
To connect to Ethernet (wired), is it a tablet or what device is connected to wired?
