I am having a similar issue. All of my other devices work fine with my wifi yet, my iphone 4s doesn't seem to connect. The laptop, that I am replying on has great connection, so I know its not the router. I tried the "Forget this Network" trick, but now it won't even accept the CORRECT password. Someone help?
My laptop and desktop computers are able to connect to my home Wi-Fi network except for my iPhone. My iPhone can detect it and when i try to join it, it will say "unable to join"
