Not sure if it helps anyone but I'm in the UK and I exchanged mine twice so far, both times was after the initial 14 days so although I couldn't return it I could still swap it and from previous experience, we can still swap them up to the time when the 1 year warranty runs out. Downside is that they've probably filtered through to refurbs now so if you're on contract and didn't buy from Apple direct, they will most probably give you a waste refurb. Which I was thinking could possibly be phones plagued with wifi issues that other people returned.
I keep feeling like I've bought a budget low end product with all the troubles I've inherited and then I remember I've bought the most expensive phone possible and have a little cry inside :(
Been on the phone with Apple again for 2 hours. He said I was the first person to call him about wifi. All I can say is I paid good money for junk. I really don't think Apple is going to fixes this. The guy Scott that I have been working with from Apple will not even call me back. I have called Apple about 40 times, and they going to tell me they have not heard of this problem. I wish that I could get my iphone 4 back. I have been waiting for software up date to fixes this,but I don't thing a fixes is coming. Going to wait about 6 months and try to get my 3rd iphone 5. Maybe I will get lucky and get on that will work. If not I will never waste my money on anything made by Apple again. Come on Apple fixes this.
Just tested with another WIFI by deleting the same application which took about 1 hour to download and downloading again which now takes only about 5 minutes. The problem is real.
With my home network, I get close to 50 mbps with my Macbook Pro, but iPhone 5 is having issue with wifi. With the second network I tested, both Macbook Pro and iPhone 5 is working fine. So where does the problem lies? ==> iPhone 5
Please somebody sue Apple for this!
I have a few questions for everyone posting to this thread. Given the variety of expertise of those posting, these questions may already have occurred to some, though I doubt all. All of these questions are about your router settings.
1) Given that the iPhone5 is a dual-band 802.11n device, is your router a dual-band 802.11n router?
2) Are your WPA2 settings identically the same for your 802.11b/g/n (2.4 GHz) and your 802.11a/n (5GHz) bandwidths (both are setup as WPA2, the SSID for the 2.4 GHz bandwidth is identical to the SSID for the 5 GHz bandwidth, the SSID is at least 7 characters long, the password for the 2.4 GHz bandwidth is identical to the password for the 5 GHz bandwidth, the password is at least 8 characters in length [preferably at least 16 characters for security purposes], the password contains upper-case, lower-case, numerical, & special characters, and all SSID cloaking, MAC address access control lists, & IP address restrictions apply identically the same way for both bandwidths)?
3) Is the channel setting for the 2.4 GHz bandwidth one of automatic, 1, 6, 11?
4) Is your channel setting for the 5 GHz bandwidth distant from the channel for the 2.4 GHz bandwidth (in the 100s or higher)?
If you answered either "I do not know," or "No," then you should consult your router settings & manual and change things appropriately or consider getting a dual-band router. Please also try searching for firmware updates for your router and applying any necessary updates.
I fully recognize this may not solve everyone's iPhone5 WiFi issues and does not negate the conclusion that some poor software issues on the iOS side likely exist. This is merely meant to help in case your issue is with your router's nominal and/or security settings.
Three other points of contemplation:
1) The iPhone 5 is the first iPhone to be a dual-band 802.11n device. The previous iPhone models capable of 802.11n WiFi are only 802.11b/g/n (2.4 GHz) capable.
2) Routers capable of providing both 2.4GHz and 5GHz bandwidth support are not necessarily capable of 802.11n dual-band. Being able to provide both bandwidths was around prior to being able to effectively utilize both bandwidths concurrently in communicating between the router and each individual end user device. New WiFi Ethernet protocols and supporting algorithms were necessary for this leap. So, in sum, you will need to check to see if your router not only has both 2.4 GHz and 5 GHz antennae, but also that it has firmware capable of the dual-band WiFi Ethernet connection negotiation algorithm. A brand new WiFi router (less than 2-3 years old) almost surely will have the firmware and antennae necessary, but will still need to be setup as per my previous post in this thread.
3) None of this excuses Apple for not programming the iPhone 5 to auto detect descrepancies and revert to the 802.11b/g/n capabilities and efficiencies of its predecessors. This is only meant as a potential workaround in the meantime. Please, regardless of whether the suggested workaround works for you, keep up the pressure on Apple to get their dual-band WiFi algorithm to work appropriately in situations where router settings/limitations prohibit dual-band functionality. Users should not be forced to adopt a dual-band environment merely because the iPhone 5 has added the potential to interact in dual-band environments. If there was only a WiFi setting on the iPhone 5 to turn dual-band off if the user wished, where said setting restored efficiency to at least the iPhone 4S level... nah... that would make too much sense to include when introducing a new feature that relies on a fundamental networking algorithm rewrite from what already works reliably well...
Guys, stop trying to fix the issue by some magic configuration changes. When EVERY device in your wifi network (and all the other wifi networks around the globe) and even other iOS/Apple devices are working fine and JUST the iphone 5 has issues, then it should be obvious what the problem is. Stop wasting your time. I think it's a psychological factor. Because apple do not respond to this problem, everyone of us is thinking that the fault must be on our site. But after all I get through and there is no finish line in sight it's undoubtedly clear that THE IPHONE 5 IS FAULTY!
Stupid Iphone 5, I hate it! I was very happy with my Iphone 4, but I losted it. So I had to buy a new one, and I choose to trust and buy the new Iphone 5 (unlike I use to do, cause I prefer to let set down the new "toys" and then buy after all the debuggin made). This piece of shxxxx is unable to logon in the WiFi at my office. I'm the only one who has to use the 3G to browse mails, apps, so on. All other devices are able to use perfectly the WiFi. I try already all the solutions mentioned, but I point one thing: we shouldn't have to reset wifi setting only to this junk be able to logon. This is probably a mixt of hardware and iOS bugs, and I'm VERY DESAPOINTED with Apple silence. But, viewing the depraciations of Apple's stocks, they should come out from their hole, even if they will be forced by share holders. Sadly, Steve is not around anymore, or this woulb be handled in a most different way.
As 802.11n has only recently gained dual-band capabilities and even more recently had hardware made to utilize/allow dual-band, it seems to me that most end users have a network that has not tested its dual-band bona fides. A "magical configuration" is required for dual-band to work correctly. That aside, Apple still has some faulty coding if their dual-band iPhone cannot interact properly with an effectively single-band network.
I found it frustrating that each support call with a new person starts off with surprise at hearing about WiFi issues, as though it's something completely new. Then half an hour later they admit they are aware of WiFi issues, and are looking into them. Given how much press the non-issue of purple flare in photos got, it's a shame the WiFi issue hasn't received the same coverage.
In my case a reboot does temporarily clear it up (which is still unacceptable for a consumer product). Though it does work fine after that, so it feels like a software solution should be possible. It has the feel of them doing something new or clever, which runs into trouble in some cases. If so, I'd like an option to turn off the automatic magic
I'm on my second device but don't think changing it again is going to help, so we're stuck waiting for software updates. I'm seriously losing faith in Apple over the handling of this issue.
I think I will let know some of major tech forum and nwespaper in my country this problem of the Iphone 5. Maybe it will start some wave to push Apple to do something. At least, other people will be aware of this faulty iphone and will choose some other solution. Apple should take responsabilty of this nightmare and place a recall of the iphone 5, say "we sorry of this problem but we will replace them with good device". That should be the Apple way to deal with sense with this problem.
I think I found the solution to the auto re-connect at home issue,it works for me anyway :)
Go to settings>WIFI>ON
Choose a network>other
Enter network name as it appears in my case NETGEAR
Security>choose from the options based on you router setting in my case WEP
Go back>will ask you to enter password>Join
Ask to join networks OFF
It has had continued connection ever since/re-connects automatically
Hope this works for you guys too
Thanks for the input Teito, at last something that sounds like a reasonable explaination for the painfully slow wifi. The router at home is old and not dualband. The ones in work I'm not sure about. They are newer by virtue of the fact the office is newer but the IT dept isnt around for me to quiz.
That said no one else is having problems with other devices so like you pointed out it's still up to Apple to fix this. They might all have the latest and greatest routers available to them but the rest of us live in a world of budgets. I might be able to replace the router at home but getting the routers in work replaced is out of the question, short of wandering around with a router in my laptop bag and plugging it in every time I sit down (I'd rather use 3G/LTE at that stage )
Now hopefully someone from Apple will at least glance this way see your suggestions and feed it to their developers for further investigation.
Dont't buy new stuff just because you have a faulty iPhone.
Apple builds in flawless dualband chips since years. I'm typing this message on a 2 years old Macbook that supports dualband with no issues. My iPad 2 dualband works like a charme. So I'm pretty sure, dualband is not the problem.
My theory of this issue:
Some (not all) iPhone 5 build in wifi chips are another revision or maybe from another manufacturer. This revision does not work well with the driver for the wifi chip that iOS 6.0(.1) delivers. In my case of slow wifi it's obvious that the build in wifi gets in to some kind of sleep mode when I stream videos over the web. The transfer rates are dropping to some pretty low level and this level will be hold exactly. This "wrong time wifi sleep mode" would also explain other problems mentioned in this thread (low wifi bar, dropping at a few feeds away from the router). A driver issue would explain pretty much every problem mentioned in this thread. Some iPhones may be delivered with a wifi revision that is compatible with the driver, so swapping works for some people but others are unlucky (me ).
