My new iPad2 will not connect to my home wifi network. When I type in the password it says 'incorrect password'. I know the password is correct because I'm able to log into the router which I need the password to do If I turn off the routers security (WEP) I'm able to WiFi connect. As soon as I turn the router security back on I'm not. This problem is the same for both my iPhone 3G and iPad2!! Help.
