My iphone used to connect to my router but then it stopped. I have replaced the iPhone four times without any luck. I use a D-Link Dir 615 n-series router. I have tried two of these routers without any luck. Of course, each company blames the other. I am 2 feet from my router and my Wi-Fi connection to my phone flip flops between connected and not connected but never really making the connection. My iPhone connects to other free access points but not to my home network which consists of two desktops, a laptop, and a new PS3. Any help would be greatly appreciated.
