Ive been having wifi issues at home and after a couple days i isolated it to having something to do with my iphone. Not heavy into networking so wouldn't know how to do any home diagnostics, but today i noticed that as soon as i got home and my iphone connected to my home network, the entire network stops working. I did the standard modem reset and unplugged my airport express, and everything works fine till i connect my iphone to my network and things go haywire. Anyone having similar issues ?
