    I wonder is there are a certain batch maybe with parts sourced from a particular vendor having these issues? Some folks have swapped multiple times and finally get one that is 100% great.  Makes you wonder.

    sbaily4: Its all partial to the whole wifi saga, every iphone 5 is not 100% identifical in terms of the hardware / chipsets, a couple of companies were involved, otherwise the problem would be identified much easier. its just hit n miss.

    What couple of companies are involved with regard to the wifi on the iphone5? If you are refering the the MAC address thing from earlier, that was wrong, they all are Apple MAC addresses. The iphone5 uses the Murata 339S0171 which contains the Broadcom BCM4334 chip for wifi.

    Ha! I missed the hair dryer fix. What's the story on that one?

    Agree with your pessimism about getting a replacement phone. The replacement phone is the option of choice for the "greyed-out" WiFi (in fact, it seems to be the only choice aside from going to a hardware guru or temp fixes like hair dryer). The WiFi flakiness is much less likely, if at all, to be improved with a phone swap.

    My iPhone 5 suffers from video streaming buffer sluggishness over WiFi as well as my friends iPhone 5. I use an ASUS RT-N66U on a 25Mbps/4Mbps connection via Comcast and I've tried everything to remedy this issue. I've been using the following video to show skeptics of the situation, which happens to be on a Russian server, so high packet loss is expected: (http://eng.news.kremlin.ru/video/blog/1153?page=1).

     

    I had Apple reluctantly swap my iPhone 5 for a one-time-only replacement yesterday, but the issue still persists, while my iPhone 4 continues to have no issues with buffering at all. If you do end up giving the swap a try, bring some video evidence of the buffering issue with you to the Apple Store because if you can't replicate the issue there (on their super-fast WiFi, like I experienced) then you might not get a replacement if you don't have any supporting evidence.

     

    I walked into an AT&T store today and tested buffering the same video on their demo iPhone 5 and it surprisingly buffered and worked as expected over their slow WiFi, while my replacement iPhone 5 buffered only a few seconds then quit. I'm posting the first few digits of the WiFi MAC addresses for your viewing pleasure if it reveals anything to anyone. It looks like I should have asked that Apple Genius yesterday for an iPhone 5 with a matching prefix MAC address as the demo iPhone 5 at AT&T... I used www.hwaddress.com to fetch the matching company name for the MAC addresses:

     

    - first iPhone 5 (slow buffer): 88:53:95 (Apple)
    - replacement iPhone 5 (slow buffer): 30:F7:C5 (Apple)
    - friends iPhone 5 (slow buffer): 54:26:96 (Apple)
    - demo iPhone 5 (fast buffer?): 98:FE:94 (Apple Inc)

     

    What are your experiences with playing the linked video above on your iPhone 5 (if you live in the US)?

    I'm with you. Dangoverts. No connection issues, but podcast downloads are painfully slow, even using Apple's own Podcasts app. And, as I've written here before, large downloads from Dropbox are virtually unusable, as is downloading large files (like complete notebooks for offline viewing) from Evernote. Same on 4 iPhone 5s, 2 of which have already been swapped, and 2 iPad minis. This on my own Extreme/Express network and in an Apple store. iPhone 4S and iPad 3 are just fine.

     

    Have you tried downloading large files from Dropbox (20MB+)? Be interested to hear if you have the same problem.

    Stephen & Dangoverts, same issue with me, no problems connecting to WIFI & also good signal strength, also speedtest.net application shows good network throughput.

     

    My problem also comes when I try to download Podcasts in either Apples Podcast App, Downcast or iCatcher.  I don't really download other large files to my iPhone5, hence this is my only symptom.

     

    Rather odd, seems that bulk data throughput is a problem for us.

     

    Oddly enough it's a little bit random, as when I was in the Apple Store raising this issue to Genius, the podcasts they chose downloaded rather fast.

     

    Side by side with my iPhone4 or iPad3, my iPhone5 ability to download Podcasts is almost non existant.

    Stephen and ozsmacd,

     

    You both mention that 4S/4 and iPad3 are fine in terms of download speeds.

     

    Which IOS versions are you running on those devices?

     

    So far I have tested iPhone5, iPhone4 and iPad2 all running Running 6.0.1 and later after upgrading to 6.1 I have tested again with the same results. They all download podcasts over wifi at a speeds around 20-80 kb/s.

     

    This morning I have tested an iPad2 running IOS 5.1.1. The average download speed on this device over wifi is around 300 kb/s

     

    To me it looks like an IOS6 problem. Do your observations confirm that?

    In case helps someone: my iPod Touch 5 had very slow wi-fi speed. Fixed in router settings. In my router control panel (TP-Link), in Wireless Setting, changed "Mode" from 11bgn mixed to 11bg mixed.

    iPhone 4 running 6.0.1 and now 6.1  = ok

    iPad3 running 6.0.1 and now 6.1    = ok

     

    Just wondering what other tests I can run that show some throughput results, do any of the Podcast apps show a Kbps etc?

    The Instacast app shows throughput in the "Downloads" list. That is where I observed the 20-80 kb/s meassurements.

     

    Instacast requires IOS 6 though, so I have not been able to compare directly with pre-IOS6 devices.

     

    My iPad2 IOS 5.1.1 meassurements were done by timing a couple of downloads in the Apple Podcast app and averaging the meassurements.

    I officially give up.

     

    The iPhone 5 is the worst Apple device I have ever owned and I have been using Apple products since 1989. I am on my second phone - the first had a bad screen. I have tried all the the network suggestions, recommendations, and fixes possible yet I could not get a reliable wifi connection ever for the past 3-4 months. Calls to Apple have not worked - the Apple Store will not replace my phone since it is fine at the store. I have emailed and complained and writting feedback galore.

     

    I have finally resorted to using TKIP on my router instead of AES. Wow! Now my iPhone 5 works great - wifi is reliable and I am happy. Luckily I have a dual-band router so am using TKIP only for the iPhone 5.

     

    All my other Apple devices at home:

    3 - AppleTV's,

    2 - iPhone 4's,

    2 - 4th gen iPod touches,

    1 - 4th gen iPad,

    1- MacBook,

    1- iMac,

    1 - Mac G5 Tower, and

    1 - MacMini as well as

    2 - PS3's,

    1 - Phillips Bluray player

    1 - Kodak printer ALL work great on AES.

     

    Apple please fix this problem once and for all!!! If the hardware is bad then recall it. If it is a software problem then fix it.

     

    I cannot believe that after 242 pages of complaints and comments in this discussion that no one at Apple has taken notice.

    br5 - like you, I tried every suggestion, until in willing suspension of disbelief, I simply removed the silicon case (Mercury VA) and full wifi service returned...go figure

    Regarding cases and WiFi problems (plus assorted other potential problems): People are frequently surprised that their case can make a difference. The discussion usually revolves around the concept that most cases (e.g. silicon) are not radio-opaque and could not, therefore, have any impact. I beg to differ with the 'obvious' conclusion. While I agree that the composition of the case may not matter, the case itself may matter. I noted early on that cases can definitely matter. My initial experience was with Palms, but has continued with various devices, including all smartphones, Kindles, etc. The issue not uncommonly is the existence of a touchscreen. By placing any case on one of these devices, it is not unusual for the case to literally create a secondary touch. As a result, the operating system software can be confused about if and where the screen is being touched. This can lead to some utterly unfathomable glitches. The result is magnified if a screen protector is also utilized.

     

    Therefore, I recommend that one should seriously consider removing cases and/or screen protectors, as MickMatt did, before completely giving up. In fact, I would recommend doing so before most other suggestions, such as resetting network settings, which can be a royal PIA.

     

    Just my 2 cents worth.

    Healz4u:  I agree an atenna could definetly lead to slower than expected speeds, that much is basic physics.  The fact is on certain networks my iPhone 5 works the way it should, and others it doesn't.  If it is an atenna issue, my phone would always get slower than expected speeds.
