iPhone 5 connects to Airport Extreme, but it doesn't connect to the wifi network
I just switched cable and internet services. I bought a new modem (Motorola) and a new Airport Extreme. I connected Airport Extreme to the modem. It took a minute to set up the wifi network and hook up to it from the computer. Instant internet on the computer. However, iPhone 5 is able to login to network, but it doesn't connect to it, though. I did my research, updated the iOS, created a new DNS (8.8.8.8), reset the wifi network services, rebooted the phone several times, rebooted airport extreme. For the life of me, The iPhone cannot connect to the wifi network. What else can I do?
