Hotel front end

Your situation is that the output port of the computer is occupied and there is a conflict.

The first method: LAN connection, just enter the toolbar in the Internet properties, and then enter Connection-LAN Settings-Proxy Server-Advanced-Don't use proxy server-fill in the address of the registered system server.

The second method: changing the port of the computer's hotel front-end registration system is a relatively simple method, but I don't know if other ports are suitable. Some software does not allow you to change the port.
