Ok this has been happening to me for about 3 years now , it has just gotten to the point where I am not going to give up until I find a solution. I used to think it was just the mobo on my old pc , yet I just built a new rig a few months ago and its still doing it. The exact problem: When I connect my xbox to computer to ftp files back and forth my wireless connection on the pc will slow down and eventually drop? This not only causes a problem with me loosing internet connection on my pc anytime I want to FTP files from pc->xbox/xbox->pc , but it also prevents me from getting a stable connection on my xbox to play online. If anyone knows what is causing this , has any solutions it would be greatly appreciated!!
