I have recently built a pc and wired it to the router. When I turn the computer on I lose my wireless on my laptop. I can see the SSID, but I can't even get access to the router. I turn the desktop off and I get perfect wireless. When the desktop is on and the wireless isn't working, I can plug the laptop in to the router and it works fine. I have a 360 wired to the router also, and it hasn't given me any problems. I've completely reset all settings on the router and updated the firmware on it. Please help!
