C# Visual Studio 2013, Tutorial 1 - Modified Servo

Hello I wanted to program my robot in C Sharp and downloaded the sample codes. In "Tutorial 1 - Modified Servo" there is a "Connect Button" for "COM3". But I have my JD-Robot connected over Wi-Fi. If i press connect there is an error. How can I connect my Robot over COM3 or how can i change the Button to connect it over Wi-Fi? confused Thanks in advance, Patrick
