    "The new iPhone 5 - you may not be a Network Engineer when you buy it, but by the time you get one working, you will be. Only from Apple."

     

    It's truly one of the most educational products Apple has released in decades! Who of you hasn't learned a new thing or two about networking this past week? And many of you got free, personalized one-on-one instruction from an AppleDon'tCare rep! This is an insanely great feature folks, not a bug!  ;-)

    I don't know. We have seen one instance of a router that was incompatible with the 2012 802.11 specifications and according to what I read, it was  fixed it with a firmware update based on customer input so it worked with the iPhone5.

     

    I think it is critically important to support WPA2-AES on both the phone and the router. Lowering your security standards would be not be recommended and should be considered a risk.

     

    This standard defines two classes of security algorithms for IEEE 802.11 networks:

    — Algorithms for creating and using an RSNA, called RSNA algorithms

    — Pre-RSNA algorithms

    NOTE—This standard does not prohibit STAs from simultaneously operating pre-RSNA and RSNA algorithms.

    The use of WEP for confidentiality, authentication, or access control is deprecated. The WEP algorithm is

    unsuitable for the purposes of this standard.

    The use of TKIP is deprecated. The TKIP algorithm is unsuitable for the purposes of this standard.

     

    The phone is really advanced based on the chip set. That's one issue. when it works, it goes really fast. Maybe too fast.

     

    There are other issues with TCP-IP that can cause problems with WIFI that are not phone related but how information is stored in such a way that the TCP-IP does not realize when to back down (bufferbloat). The carrier connections don't have that problem because they  shrink the buffers for the phone compared to your home computer.

     

    So the phone will use both channels at the same time, which has been out in routers for a couple of years now. If it were me, I would go somewhere and pickup a new router that supported the same feature set and return it if it didn't work. If it didn't work with my current router I would call the manufacturer's support and find out why not.

     

    On the other hand if the phone is defective in software or hardware I would expect Apple to come up with a solution once they can track down exactly what is causing it.

     

    They really can't be entirely resposible for pushing the envelope for higher performance if that is already been blessed as the right thing to do by the people writing the standards. And they did get it certified.

     

    What really concerns me is reports of data usage for some people who don't know their WIFI is not working, and they will get sent a huge bill for data usage. That's the looming issue.

    LOL Eric.

    yeah... buying an iphone 5 comes with a lot of incentive for personal growth... sigh

    "I don't always connect to my encrypted network, but when I do I prefer my iPhone1."

     

    Do you suppose there would be licensing issues with t-shirts portraying a big Apple logo and:

     

    "Apple don't care"

     

    or

     

    "Apple doesn't give a s$%t!"

     

    Ala the Honey Badger?

    My question on that is why does every other device I've bought including recent ones work great on the same AP?

     

    Backward compatability.  If they truly have introduced something based on new standards in the iPhone5 or iOS6 I don't see where there is any excuse for not falling back and supporting older standards either automatically or through a manual method in the settings.

     

    Sure, I can upgrade MY AP and maybe it'll work.  I can't expect that of the businesses, hotels, or other locations that might offer customers and employees an encrypted connection.

    One of my Airport Expresses is only a couple months old. No go.

     

    Phil is very knowledgeable and makes some great points. But how can Apple collect this data if they are routinely sending people back home from their service centers without properly testing the devices?

     

    I can understand playing devil's advocate and continuing to be concerned that people who are just now noticing the problem might prematurely jump to the conclusion that their phone is defective. But a lot of us are way past that.

     

    If Apple are concerned about people returning good hardware, they need to arm their service personnel with proper troubleshooting techniques. There are a number of us that have been sent packing without the rep simply testing the phone on an encrypted network. It's not our job to figure out their problems. You should be able to try a reasonable number of troubleshooting steps, and then if it still doesn't work, take it back.

     

    In the long term, it's much worse for the company to keep trying to force obviously bad units down the throats of their loyal customers.

    So my iphone 5 was delivered on day 1.  Performance was great and fast.  I didnt have problems connecting to secured Wifi- my problem was that everything I was doing online was much slower than the ipod/ipad/idevice next to me.  Something didnt seem right no matter what trick I tried: 

     

    Add "test" to the description of the wifi in the settings, and renew lease

    Switch router to WEP (oh **** no)

    Reset the phone

    Reset network settings

    Check if your router (mine is a 4th Gen Airport Extreme)

    Pretty much every tip that was posted on forums using "iphone 5 slow wifi" in google search.

     

    Anyway, two days later I said screw this.  Made an appointment with the Genius Bar, next day the phone was replaced.

     

    Same thing.  It'd be all nice and fast browsing but it seemed to degrade after about ten minutes.  ***.  Same thing- search for new posts on the forums I was checking everyday.  My big gauge wasnt only just the browsing, I gauged my connectivity by downloading large pdfs off my dropbox app.  Still slow and of course my other devices using the same app was fast downloading.  App store apps that were bigger than 50megs seriously took 30+ minutes to install/load even after troubleshooting and accepting hey its a new phone maybe a million people are downloading the same thing.

     

    So i said f this again, made another appt with the Genius bar- so I explain to the guy what I was seeing (and hoping he read the forums and knew what I was talking about).  I caught his attention and he whipped out his 4S and downloaded a large file onto his own phone.  Wham.  Fast.  I show him my dropbox app and explained how I gauged my 5 with other idevices.  He said, and it makes sense, well the dropbox app isnt IOS 6 ready and something about the APIs and yada yada.  So there was no exchange.  I figure ok well ill just wait til they update the app but it still didnt explain the slowass browsing on my WPA2/AES set Airport Extreme. 

     

    Today:  went to the Apple Store, talked to a genius guy, replaced my phone for the 2nd time.  And guess what.

    Everything is FAST INCLUDING MY BROWSING, AND MY downloading bigass pdfs are fassssst like the rest of my other idevices.  Surprised?  Yeah and glad.  And lucky I didnt get what I think was a bad phone from a bad batch of phones sent out.  As i was driving home, I was thinking what if I got the 1st phone back as the replacement.  Haha

     

    Good luck guys.  Exchange it and hope the replacemnts in that drawer they pull the replacements from is from fresh batch.

    Oh ya and my wifi address four number thing is:  68:96.  I believe the one i gave back to Apple was oddly the same four starting numbers.

     

    Aloha

    Anyone having network speed issues, download the Speedtest.net app in the App Store and you can measure the actual speeds of your network.

    Speedtest isnt a true reflection of your local wireless connection... more your internet connection.

    You're right, but people who are having speed issues are saying that downloading data from the Internet is slow. Speedtest will help them put a number on it which they can compare to other networks and their cell connection.

    Good info, but that's a different problem. The AES encryption problem that this discussion is around, you connect to an AES Encrypted WAP, have blazingly fast speeds for variable times, could be 30 secs, could be 10 min. Then, all internet connectivity stops. Period. There's no "speed" to measure. Sure, the gray bars are lit up, but you're getting nada from the internet. App store, Safari, Mail, nothing works until you reboot, toggle wifi, erase network cache. Then u have it for another few minutes. Reliably. Then it stops. Reliably. And it messes up on ANY AES network, reliably. Regardless of router brand or firmware, etc.

     

    I'm not sure "working but slow" is the same problem. It might turn out to be that it is, or it might be related to anntenna, DNS, software, or Apple's fave excuse: "Network Conditions". The speed issues should probably have their own forum, or be in the general Wifi issues forum. We're alll pretty cut & dried and practically identical on our problems with the AES issue here.

    I don't know if the slow WiFi problem is another issue altogether or just a different symptom of the same problem. Could be. There's definitely a WiFi problem, though. That's for sure. Like I said, I hope this is a software issue as I don't want to go through the hassle of replacing the phone. I don't have an Apple Store that I can just walk into and walk out with a new phone.

    At the moment I have some success using WEP, but that too is a bit unreliable in terms of internet connectivity. I've removed all security features on my WiFis and made them hidden for the time being until there is a fix.

    My post was mainly in response to Funcher, who said he gauged speed by browsing and downloading large documents.  He also said that he had s fast connection for a little while and then it slowed down, but he was still connected with much slower download speeds.

     

    This was also my problem. When connected with WPA2 AES, I was getting very slow speeds but I didn't lose connection completely. When I removed encryption or changed to WEP, the normal speeds returned. So it's definitely in line with the title of the discussion.
