So here is my story, I have my main machine whitch has a wifi card and the standard built-in gigabit ethernet. I get my internet connection from the wifi card. I have another computer with just built in Ethernet as well, My main machine is running windows 7 x64 and the other computer is running XP x86 I want to be able to connect my main machine to my ethernet switch and the other computer to the ethernet switch and be able to get internet on the spare computer. Now here are the issues: 1. How do i set up the spare computer to get the internet connection from my main machine? 2. Whenever i connect the ethernet cable to my main machine all my programs (firefox, pidgin, steam, ect) try and connect to the internet through the ethernet connection, but there isn't a internet connection present there only throught the wifi card. How do i fix this so that even if i plug my ethernet cabe lin it will still try and connect to the internet through the wifi card? 3. I also go to my fathers on the weekend and i get my intrenet through ethernet there so i need to be able to switch back and forth preferably automatically.
