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,

C

iPhone 5, iOS 6

My Wi-fi MAC is 98:FE, which is registered to Apple. This is my second phone, and this one does NOT have the WPA2 issue (first one did.)


So while there may be something to Intel chipsets not having the problem, there are Apple chipsets (or at least phones with MAC addresses assigned to Apple) that don't have the problem. It's entirely possible Intel is generating chips with Apple MAC addresses.


We exhausted the number of unique MAC addresses years++ ago. We're recycling these days, and manufacters have used MAC addresses that were isused to defunct companies. It's possible Apple gave Intel a range to use.

Did you all purchase directly from Apple? I have WPA AES issues as well with my phone and my wife's phone (both 16g white 5's). We ordered ours through AT&T and I am not sure if I should call AT&T or if they will just send me to apple store for replacements. I would rather not waste the extra hours getting the runaround.


On a side note regarding the tech specs. I too have apple made chip.

Iphone 4's running IOS 6 have no issues whatsoever on home network which is WPA2 Personal.


Thanks,

Nice thought, but this is false. My replacement phone that works perfectly has a WiFi chip that is Apple Manufactured. MAC ADDR 98:FE...


Also, my wife's phone that worked perfectly out of the box, also has a WiFi chip that is Apple Manufactured. Both phones connect to my WPA2 enabled Airport Extreme without issue.


I applaud your efforts, but both my phones blow holes in this theory.

No, I think you're misunderstanding the theory. It's not that 100% of the Apple chips are bad, just that the problem is confined to the Apple chips. We haven't seen a buggy Intel reported on here yet.


That said, you make an important point: it may not be the end of the world if you get a replacement with an Apple chipset. Thank you!


I'd imagine if 100% of the Apple chips were bad, this would have been headline news on day one!

The point here is not apple or Intel chip , I think we all need to discuss which wifi routers/firmware are you connected to.


Looks like iphone 5(both INtel and apple chips/Ordered from ATT or replacement in apple store,) work fine on some firmware and routers.But on some they have strange behaviour either no connection at all or no connection to secured etc..


So lets start sharing info on wifi Routers and Firmware.

Oct 2, 2012 11:11 AM in response to C4RLOCO

Unfortunately this is not true for me. My MAC (Wi-Fi) address of my iPhone 5 starts with 88:53 and I have very weak Wi-Fi signal strength from just 5 feet away from my wireless router. I tested with another wireless router I have and set it up with no encryption and still had connectivity issues with my iPhone 5.


My model is a 32 GB Black for AT&T. It was made on week 38 (9/17 - 9/23) and is running modem firmware 1.00.16.


I'm pretty sure this is a hardware issue on my iPhone 5, but unfortunately the MAC address doesn't seem to hold true for me.

Also, please confirm that your routers are using AES encryption, If not, please go to the other thread:


Won't connect:

1) Airport Extreme N 802.11n (2nd gen) FW ver 7.6.1 (latest)

2) Airport Express 802.11n FW ver 7.6.1 (latest)

3) Whatever enterprise routers used in my office


I do think it's an interesting data point which chipset you have, since that's apparently where the Encryption process resides, according to a tech doc referenced on the other thread.


We've yet to hear from an Intel chipset owner who reports this specific AES bug. Doesn't mean all the Apple chips are bad, obviously they are not. But could be a specific batch, and that would be very useful info for Apple engineers working on this problem.

It does sound like my issue is different than the other ones posted here. Sorry about that.


To answer you question though, I was able to successfully connect to an AES encrypted WAP and say connected without any issues as long as my phone was literally right next to the WAP. Once I take my phone further than 5 feet away, the connection will eventually drop. I noticed this Wi-Fi issue immediately after unpacking my phone and I noticed it had troubles locating my WAP which was less than 10 feet away.
