We have 3 lease lines for internet connectivity in our office. When there are issues with internet connectivity, the office staff has to go to RUN --> ncpa.cpl --> Right click on network --> select properties --> TCP/IPV4 --> Change default gateway value to shift between lease lines.
I would like to develop a .NET program that is able to detect at runtime the internet connectivity and change the gateway.
I donot want to use programs available on internet, rather, create my own simple application. Please provide some usefull reference for this, I have experience in .NET coding.
