Q: Wifi is not connecting for some devices on my Airport Extreme.

Wifi is not connecting for some devices on my Airport Extreme.  I tried the following two connections to modem.

 

Modem -> Airport Extreme (version 7.7.3) mini-ipad (6.1.2) works, mac air (10.9.3) works, iphone 5 (7.0.6) works, iphone 4 (5.1.1) doesn't work!! It give me the “Unable to join the network” message.

 

Modem -> Airport Express (version 7.6.4) all of the above works, even iphone 4 works!!!

 

Why??? Is this because iphone 4 doesn't support the newest AE configuration? Or is it the 5Ghz problem?

All my devices are all APPLE products and still it doesn't connect seamlessly.

 

Please help, thank you!

Mac OS X (10.6.6)

    Hello Geehong,

     

    Thanks for using Apple Support Communities.

     

    Since you have already isolated this issue to your iPhone 4, please follow the iOS Wi-Fi troubleshooting article linked to below.

     

    1. Be sure you're in range of your Wi-Fi router (access point).
    2. Tap Settings > Wi-Fi and turn Wi-Fi off and on. If your Wi-Fi setting is dimmed, follow these steps.
    3. Confirm that your Wi-Fi router and cable or DSL modem are connected to power, turned on, and connected to the Internet. If not, refer to your network administrator or Internet service provider (ISP) for assistance.
    4. Restart your iOS device.
    5. Tap Settings > Wi-Fi and locate the Wi-Fi network to which you're connected.
    6. Tap and Forget this Network.
    7. Try to connect to your desired Wi-Fi network.
      Note: You may need to enter your Wi-Fi password again if your network requires one.
    8. Turn your Wi-Fi router off and on2. If your ISP also provides cable or phone service, check with them before attempting this step to avoid interruption of service.
    9. Update your device to the latest version of software.
    10. Update your Wi-Fi router to the latest firmware2. For AirPort Base Stations, install updates using the AirPort Utility.iOS: Troubleshooting Wi-Fi networks and connections
