    I would agree with Jameson's observation.  6.0.2 is a huge improvement.  I test throughput from my iPhone 5 to the Ruckus 7363 access point through the router through Verizon FIOS to the Speedtest.net server about 1 mile away.  With IOS 6.0.1 the download traffic displayed in the small graph on the left side of the Speedtest view was fairly smooth and runs consistently at 20+ Mbps.  The upload traffic shown on the small graph on the right side of the screen was very choppy with the speed varying from 0 to 18Mbps.  Consistently the upload traffic would freeze about 2/3 of the way into the test indicating that a memory buffer in the iPhone was probably full and the SpeedTest app interrupted.

     

    6.0.2 resolved most of this problem.  The download traffic flows smoothly and the speed has increased about 30%.  The upload traffic is still somewhat choppy compared to the download traffic, but doesn't freeze the app.  So the buffering of outbound WiFi traffic has been improved considerably and the underlying bug causing the app to freeze looks to have been resolved.  It makes sense that download traffic is optimized, but it would be great if Apple continued to improve the WiFi interface so that upload traffic was also better optimized with a larger buffer size.  This would help when tranmitting video in apps such as FaceTime.

     

    I'm pretty sure the problems are isolated to the iPhone 5 and not the access point.  Over the past 3 weeks I tested with an HP MSM422 access point using both 2.5GHz and 5 GHz radio transmitters and configured the device for the least congested channel.  802.11n upload traffic from the iPhone to this HP access point froze consistently.  Swapping out the HP commercial access point for the Apple AirPort Extreme Access Point and testing with both transceivers using a different SSID for each transmitter resulted in the same hangs on the iPhone 5 running 6.0.1.  Tests were run with the iPhone near each access point.  I was having coverage problems with the HP MSM422 access point and tried the latest model Apple Airport Extreme which provided much better coverage in my home, but still not great.  After doing some research and a knowledgable friend's recommendation to test with the Ruckus 7363, I installed the 7363 and was shocked at the improvement in WiFi signal strength between the iPhone and all parts of my house.  This was true for both 6.0.1 and 6.0.2.  Now with 6.0.2 installed on the iPhone and the Ruckus 7363 AP permanently installed in the house I'm consistently gettring 27 Mbps downloads and 20Mbps uploads and quite happy.  If Apple improves the buffering on the upload side, then I would expedt to see my upload speed to go even higher.

    That looks like a really good access point.  But at that price point (MSRP $699), there won't be one in my house any time soon.

    I think this is not a software problem anymore, Apple has made an iPhone 5 with faulty wifi antenna. Period.

    I installed iOS 6.0.2. Still wifi as slow as ever.(iPhone 5)

    I tried resetting network settings didn't help. Slow slow hardly getting any data, well below 3G speeds.

     

    iPhone 4 etc still working good with normal wifi speeds.

    I don't know that we can conclude at this point that it's a hardware issue. We have an iPhone 4S and an iPod Touch 4th Gen that, since updating to iOS 6 (and 6.0.1) have also had very slow Wi-Fi. On iOS 5, they were running just fine.

     

    That being said, this issue has been more difficult to nail down as there are definitely some iPhone 5's that seem to be working just fine. It seems, at this point, that whether or not they're working might be dependent on what router is being used. However, it's not even THAT simple as some people are reporting some of their iPhone 5's upon replacement are working fine.

     

    Bottom line - this is a complicated mess that's finally beginning to get some attention from Apple so hopefully it'll get resolved - one way or the other - soon.

    I agree that it is most likely a major flaw in their software.  My iphone 4 was working fine.  Then immedietly when I installed ios 6, it stopped working with my dlink dir-625.  My new iphone 5 also is not working with wpa2 even with 6.0.2.  I'm very dissappointed that Apple introduced an error and has not yet fixed it.

    Ok, it has been two days since I upgraded to 6.0.2.  I have tested at two public hot spots both I have been having problems connecting to using 6.0.1.

     

    One of the hot spots was much better.  The phone showed I was connected but it was not.  Once again the phone did not resolve the routers IP or DNS until I toggled from DHCP to static and then back to DHCP, this is the same as 6.0.1.  The thru-put was extremly better.

     

    The second hot spot was exactly the same as 6.0.1.

     

    People, get this problem out to the media!! We all know Apple will never admit to this issue!!

    This may just be an isolated issue, but since updating to 6.0.2 I can't backup to iCloud. It starts going but then it stalls out & gives an estimated time of 15-16 minutes before failing to complete the backup.

     

    Is this happening to anyone else?

    Got the iPhone 5 a few days ago and just started noticing (post 6.0.2) some extreme wifi issues. As per the speed test app, my download speed is ~1.5mb/s with wifi ON and ~15mb/s with wifi OFF. What's going on here

     

    Router is a Netgear WNR2000

    Same issue here! The update 6.0.2 didn't solve the WIFI bug, but creating another BIG BUG. APPLE shall introduces iPhone 5 without WIFI. What is the point if phone has WIFI but unable to use.

    My guess would be that the issues with wifi stem from an issue or limitation from the hardware and they can't get the software right to make it 100% consistant. 

     

    Since 6.0.2 I've had more issues than before the update.  I'm counting on an update soon or I'll be selling this thing 3rd party and maybe even going back to a 4.

    "Same issue here! The update 6.0.2 didn't solve the WIFI bug, but creating another BIG BUG. APPLE shall introduces iPhone 5 without WIFI. What is the point if phone has WIFI but unable to use."

     

    the point is we keep paying money for products which don't work - then pay more for the next iteration in which some faults are repaired, but new faults emerge and so on.

     

    its a great business model really. if everything worked perfectly from version 1, no-one would be forced to update to v1.1, v1.2 and so on..

     

    unlike what their CEO says, they are not in the business on making great products...they are in the business of making money, by whatever straws they can find.

    I seem to be having a slightly different problem than everyone else

     

    1. My wifi was working perfectly until about 3 weeks ago. It just stopped working well. In what sense?...
    2. I have lost extended range on my wifi signal at home. My 3GS (6.0.1) and Macbook Pro are working as normal, but the iPhone 5 (6.0.2, but 6.0.1 at the time of the issue) can no longer be at the same distance from the router (Airport Extreme, fully updated). It can't pick up the signal (Cannot connect to wifi network) unless I get closer. If I get closer (within 2 wifi bars) it connects just fine and the speeds are perfect.
    3. Outside my home is a different story. I can no longer connect to any wifi hotspot (e.g. McDonalds, Tullys, Starbucks, free mall wifi, etc). It just can't connect to any of them at all. NOTE: I haven't tried connecting to hotspots after 6.0.2, but at least my home situation is not fixed by the update.

     

    My speeds have never been affected, just my connectability and range.

     

    We have a data cap, so this bug is really killing us right now. We need a good fix for this, please.

    I did not have any wifi issues until I installed 6.0.2.  Now my iPhone 5 drops wifi connection every time it goes into Auto-Lock.  I have to reconnect after I unlock the screen.
