Win 7 On Desktop

I have three pc running Win 7. Two are wireless on the network. The third is a desktop wired on the network. Both the desktop and NAS are plugged into the same router. If the desktop is off we don't have any issues connecting wirelessly to the NAS or thee internet for that matter. The monent I turn on the desktop, the NAS loses its connection and none of my computers can access the NAS or the internet. What, in Win 7 on the desktop, is causing this is happen?

Are you using fixed IP?

Can you run ipconfig /all and upload the output to us?
{start>cmd>right click and run as admin>ipconfig /all}
