Guys, Got a problem with an iPhone 4 that simply will not connect to our home Wi-Fi!! Some background - we have 3 x iPhone 4 in the house - and 1 X iPhone 4S The network is two Apple Extremes and a few Airport Express units. The phone in question will connect to external Wi-Fi networks - it will connect to another Wi-Fi network we have in the house...BUT not the main network. Every other phone is fine - and they all have the same settings and updated 5..0.1 - etc - this phone has been a problem even before IOS5 - and its just bizarre - as it will connect elsewhere. If I was to take it to the Apple store I'm confident it wold connect to their network and they'd say "theres nothing wrong with it"?? SO I am at my wits end with this phone! I've tried restoring it twice - I've tried re-setting the network - the network has the latest firmware - I have tried forgetting the offending network and re-joining - I've tried everything! When I try to join the network it asks for the password - then the circle thing just churns away but never connects or gets the "tick" Anyone got any ideas?? Thanks!!
