iPhone5 issues with WPA2/AES Wifi

I am using a Dual- Band Linksys E2500 router with WPA2 Personal (WPA2/AES) enabled. None of my other apple products (iPhone4S, iPhone4, iPad2 and the New iPad) have had problems connecting to my router. But everything changed when I got my iPhone5.

Basically the iPhone5 is capable to connect to the WPA2-Personal wifi network but after 1-2min starts to drop network packages, hence, I cannot browse any page (not even the router page 192.168.1.1) even though I still have a valid IP and the wifi icon is shown on my top screen.

I pinged the phone from my router diagnostics page and while I can browse the web with the iPhone5, I can see no packages lost. However after 1-2min the iPhone5 cannot open any websites while still connected to the wifi, it starts to show network packages lost.

A workaround that I found was to create a "Guest" network (which is not WPA2-Personal) or even WEP. There are no issues when connecting to these alternate networks.

Can anyone out there confirm this issue?? Is it software or hardware related?? It seems to me there are issues with WPA2-Personal (WPA2/AES)

Thanks in advance,

iPhone 5, iOS 6

My phone's serial number starts with C3 which shows as China, but no other factory information available from that link above.

Just swapped mine out. The replacement is from DN and Week 37. It's working perfectly so far.

Hello C4RLOCO,

Sorry you are having issues with connecting via wifi. I have the Linksys E2500 router as well. Guess what? I had issues connecting via WPA2 Personal. I switched the router to WPA with TKIP encryption and it worked flawlessly. The issue is keeping a sustained connection with WPA2 /AES as we have discovered.

Today, I went to the Apple Store and told them about the issues I was having, which was connecting to routers that are WPA2/AES. The guy understood basic networking, so this was helpful. I told him my problem sounds like several who have already posted on the Apple Forums. He quickly found several discussions relating to WPA2/AES issues and agreed I must have a bad phone if I am having problems keeping a solid connection. They replaced my iPhone 5 (32gb) without any hassels. Now, it wasn't until I got home that I could test device because they did not have a WPA2/AES setup in the Apple store. Fortunately, my new phone has no issues connecting to WPA 2/AES at all, so the riddle has been solved and I am happy now.

Does anybody know if this is hardware or software related? I believe a bad batch of phones must have been released before Apple could correct.

Thanks and hope this helps!

I use a Cisco 1142N AP in my house. Switching from "AES CCM" to "AES CCM + TKIP" helped. Give it a shot.

Spoke to support and they are replacing it.

They tried to charge me £29 for a courier charge but I told them I wasn't happy with that so they put me through to sales and the guy there arranged it without the charge!

I have enterprise network setup and my boss' iPhone 4S upgraded to ISO6 works find. I see many people have AES as the encryption type. Try using it just the TKIP. I have access point setup as that and I does not seem to have problem.
