    I updated my 4 iPads, iPhone 4 and purchased an iPhone 5. All function fine with wifi.  My iPhone 5  and new iPad with wifi + 4g, maybe I am fortunate but I found out years ago with router issues even when I got my Airport Basestation that the channel for Apple works best under channel 9.  Maybe this will work.

    Did you guys try changing/downgrading/upgrading your router firmware ?

    See my post.https://discussions.apple.com/message/19846438#19846438

     

    There is surely something different with WIFI connectivity on iphone 5. I had IOS 6 on my iphone 4, everything was working fine, on all wifi networks. But Iphone 5 Won't work on some of the routers/firmware.

     

    Ofcourse if you are conecting to a public/Company WIFI (like most of us), we have no option but wait to get a fix for Iphone 5.

    Ok Folks! UPS just dropped off my new replacement iPhone5 and I have an update for you: The new replacement works BEAUTIFUL with my WPA2 network and I did not change a thing. I got the new phone, restored my backup and I was able to connect and hold the Wifi connection.

     

    The problem with the WPA2-AES connection issue IT IS HARDWARE RELATED! Here is my explanation given the fact that my new replacment works very well.

     

    The iPhone5 with WPA2-AES issues has a MAC Address that starts with 98:B8 (Apple Manufactured)

    The iPhone5 with NO WPA2-AES issues has a MAC Address that starts with 88:53 (Intel Manufactured)

     

    You can check your WiFI chip manufacture company here: http://www.hwaddress.com/ (You only need the to enter the first four letters/numbers of your MAC Address. Where do you find your MAC Address? Go to Settings->General->About ->Wi-Fi Address

     

    I'm glad that this nightmare is over for me. I strongly encorauge you replace your phones NOW!. Do not wait for an update since you more likely need a new WiFI Chip that has not be manufactured only by APPLE and ensure that INTEL is the one on your phone.

     

    Next time, you go to the Genius bar, you can check this and get the proper replacement that you need. Just stay away from any Wi-Fi chip with a MAC address that starts with 98:B8

     

    If you have any questions or would like to check settings against my phone configuration, please do not hesitate to contact me and I will be more than happy to help. As soon as I finish this post, I am calling Apple to let them know my finding and see if they finally can acknowledge the defective Wi-Fi chips on some iPhone5.

     

    P.S: My only complaint now is that the new phone came with some scuffs

    scuffs? you just lost 50% of its resale value. If I were you, I'd get another one. that's not acceptable.

    Was your first phone failing to connect / holding a connect or inconsistent download speeds?  My download speeds are varied. I have a 98:B8 address.

    My phone was connecting to any WiFi network except WPA2. Meaning, it will actually connect to WPA2 but no traffic will go through.

    Interesting.  I'm on a WPA/WPA2 and have the varied speed issue, but not the blocked data issue.
