This is really a strange one. At work I have to keep my Iphones WiFi connection off. If it connects to the WiFi at work then My computer and the person's computer next to me (both Windows based) loses it's internet connection. They are wired connections. We have to open up the Local Area Connections Status screen and if we press repair connection it restores it and it works for awhile but it will lose it's connection again shortly and we then again have to click repair connection. I have definitely traced this to my Iphone as I can turn on the WiFi and the problem occurs and upon turning off WiFi on my Iphone the computers again function as normal. We can both use our Laptops (Windows or Mac)with wireless connection and this problem doesn't occur...it just seems to be the Iphone's WiFi connection. This is baffling. Has anyone else ever experienced this. Thanks for any insight.
