    I've been posting on a similar thread here:  https://discussions.apple.com/message/21223033#21223033

    I'm quite convinced that my problems are related to the interaction between a 1st Generation Airport Express and an iPhone 5 running 6.0.2 or 6.1 as the problems arose only after switching to those.  My other iOS devices are fine.  I was hoping that the most recent updates to the Airport firmware would have fixed it, but no such luck.

    Some observations and possible compromises in leue of a fix from Apple:

     

    The iPhone 5, unlike the iPhone 4/S, has a cliff it seems, rather than a slow fade as one moves away from the wifi source. I'm guessing that Apple is pumping out a very strong signal or signals in the stores. At home, I can mark the line in each of our 3 floors where the cliff is. So on the good side of the line I can get 20mbps, go over the line and I get 1 – 2mbps. It's that dramatic. The iPhone 4s in the house fade as one might expect as the signal tapers off.

     

    Also, Speedtest seems to have a signal issue on iPhone 5s. I get long, long pauses before seeing a solid diagonal line drawn towards the bottom left of the download test. On the iPhone 4s there's no pause. But Speedtest X HD doesn't pause when testing at all. Speedtest says an iPhone 5 compatible version is forthcoming.

     

    When I extended my wifi at home with an Airport Express and turned down the multicast rate, I no longer got the "full wifi icon but no data throughput" thing. Again, it appears there is a cliff for this issue as well.

    The iphone 5 is dual band while the old airport express isn't...maybe you're on to something?

    I think the original Time Capsule, though, is the same as the Airport Express.  If I reset my Airport Express and toggle the WiFi on/off on my iPhone, then it will (usually) work on the Airport Express until I move away from it - its almost like it has difficulty going back-and-forth between the Airport Express (which is in network extender mode) and the T|C.

    Now THAT makes sense. So the "line" or cliff I'm experiencing is the transition from the Time Capsule to the Express. Well, not like I can do anything about it, but like Fred Flintstone said: "Knowing it is half the battle."

    i have a new dual band airport express as my base station and an older single band airport express as an extender. i put airport utility on my iphone 5 and when i rest my phone on the old airport express and open airport utility on my phone it says 'connection good', when i click on the new airport express i get 'connection excellent', even though the phone is basically on top of the old airport...don't know what this all means, i'm just providing some info. we've not had wifi problems with our iphone 5's though.

    All my Airport devices are non-dual band. So, is this a "buy all new Airport dual band devices" and all will be peachykeen?

     

    Is that was this is, then? An "iPhone 5 plus non-absolutely-current Airport wifi device = crud" thing?

    Good find, MrLux Yacht! My problem is the exact same - as I move away from Airport Express and TC, connection speed just plummets. Due to my location of the Express, I didn't realize that it was a distance issue. Also, the Airport Utility shows my connection as never more than "Good", even next to the routers, when all my other iOS devices get "Excellent", even at longer distances. Could this be a hardware issue with the phone? Or could the update have messed up the power to the WiFi antenna or something similar? I think I'm going to try to get a replacement. My phone isn't even a month old.

    Well I gave in and sent my phone to apple to hope for a replacement

     

    My replacement iPhone works on my wifi. Woo!

     

    So its pretty clear to me that the issue was hardware, at least in my case

    Kosherwaffle - thanks for letting us know. Did your iPhone work on any wifi networks before you replaced it?

    I had my iPhone 5 replaced last night at an Apple Store.  They could not guarantee that everything would work fine and recommended that if it didn't, I should set up my iphone as a NEW phone and not use a backup. 

     

    My home wifi (Time Capsule)  connected without a problem and stayed connected all night, and automatically reconnected after a long walk with the dogs. This hasn't happenend since I updated to 6.1. 

     

    My wifi at work (Linksys) took a little effort to connect, but has stayed connected.  Keeping my fingers crossed.

    Miamiwire - what version of iOS is on your new iPhone?  Also, what did you tell the Apple Store to get them to replace your phone?  Thanks for sharing this news.

    Spoke to soon!  My work wifi dropped on my new phone. Looks like I'll be spending the night re-installing.  This is a 6.1 glitch.  Not hardware ....

    I have had my Iphone 5 for 3 weeks no problems till yesterday . I could not get wifi to connect and if it did it was only for a few seconds.

    I bought a new case and put it on yesterday ! Took it off this morning and ....low and behold ....the wifi is back to normal. Could it be this cheesy aluminum case has blocked my wifi ?

    Well all I know is it works now
