If you are using multiple NIC's (Network Adapters) to access more than one network, it gets tricky from where you internet connection comes from. Here is one such scenario and solution to make Microsoft Windows prioritize internet connection from a particular network over the other. In my example setup I have one LAN connection (192.168.0.1) and one WiFi connection (192.168.1.1) and would like Windows to use internet from my fixed-line broadband connected via LAN.
