Q: iPhone 5 wifi issues

My Iphone 5 has a lot of packet loss on my 2 different home routers, no issues with an Iphone 4 on IOS 6 or any other WIFI device. I upgraded the firmware of the routers, changed the security for tests to WPA1, WEP and unsecure with no success. I replaced my Iphone 5 32GB for a new one, without success. The funny thing is that when i connect to the WIFI network on my work I got NO ISSUES! It seems that the Iphone 5 is incompatible with some routers . I got 2 2.4 ghz networks and 1 5Ghz network in my house but also on the 5Ghz band i got the same issues.

If Apple doesn't fix this problem very soon I'm going to return it and never buy Apple products again! I paid 800 Euros and I get this crap and high bills from my provider.

I have exactly the same problem. Is there a way to return the software to 6.0.1?

****, just got a new iphone 5 and activated it via wifi. Everything was fine until I updated to 6.0.2......

If I move 3 meters from the wifirouter the iPhone loses connection.

Crap!

That wouldn't have anything to do with iOS 6.0.2.

Try Settings > General > Reset > Reset network settings to see if that corrects the problem. If not you may have a hardware problem.

No. Read my response above for a suggestion.

I disagree with you, JimHdk.

Unless you are with Apple Product Development and/or Support, how can you make such a huge assumption?

There are hundreds of responses on here from people who were on 6.0 or 6.0.1 with no issues whatsoever, and the very minute they update to 6.0.2, they lose their WiFi capability or it is severly crippled.

Keeping in mind that there are different issues going on with different users and there are probably different iPhone lots that have slighlty differing parts inside, how can you dismiss this for these people that were fine until the update?

I'd like to hear your thorough explanation.

Well, I and many, many others updated to iOS 6.0.2 and have had no problems at all so I don't really see this a a "huge assumption".

It seems quite unlikely that iOS 6.0.2 would cause a drop in range of WiFi reception to 3 meters.

That could, however be caused by a problem in the installation of the WiFi driver firmware during the 6.0.2 update which can be corrected by using Reset network settings. There are, of course, other hardware problems which could cause diminished WiFi range. By the way, I believe that all iPhone 5s are using the Broadcom BCM4334 WiFi/Bluetooth/FM chip.

I'd like at least few people in this thread to be given a chance for a solution to their problem rather than rule out any posts other than "Apple is the great satan who has release a demon upon us with the name 6.0.2" Luckily it wasn't iOS 6.6.6.

Haha! Good points.

It would be great if we had a way to report the hardware manufacturer info of the parts inside our phones.

I'm guessing the update did change something with the driver or chip, such as updating the firmware on a DVD or Blu-Ray drive to add/change features, but might be fixed with your Network Reset suggestion.

I'm up and running again (for now, and it seems to be working.)

My fix was to change my WiFi cypher type on my router to AES only. It was TKIP and AES. I then deleted my connection (Forget Network) and created it again. Maybe that achieved the same purpose as a Network Reset.

Twanaguh,  What are you using to determine packet loss?

Thanks,

I'm curious how you are so certain that your phone is ok?

ie: I assumed I was ok because my phone connects to the wifi both at home and work just fine.  The problem is, when I download apps or do anything requiring internet it is using the 4G service no matter what.  When I get home 4G doesn't exist so it is more noticable there because I still have wifi but it won't download anything.

So how are you so certain that you don't also have the issue?

Thanks,

Sorry JimHdk,

I don't think it's a funny thing. I just reseted network setting and still wifi doesn't work properly. Before updating 6.0.1 it worked perfectly, today it start working and stop, etc.

You should take this more seriously, i am a developer too and I am ****** off by this thing : my first Iphone 5 came with a dead pixel (and wifi ok). They changed it by a new one at Genius bar. It was in 6.0.1 and worked well with wifi. Then I updated in 6.0.2 and it doesn't work anymore.

Honestly, I am waiting for 6.1. If the problem still there I will ask for a new change at genius and ... if the problem still there I will ask for my money back.

It's still too much issues for a so expensive device. I am so disapointed, maybe making a new Iphone each year is too much for quality ?

Take care Apple, Giants can fall.

Obviously I have checked to make sure that my iPhone is not using cellular data and have checked my upload and download speeds with Apps like Speedtest as well as noting the time to do things like downloading Apps.

I don't have any problems.

You do realize that everyone on this forum is a user like yourself I hope!

No one here is working for Apple. Apple merely hosts these forms. The forums are strictly user to user.

If you have a problem that you think needs Apple's attention then contact Apple support. You are NOT talking to Apple or Apple employees here.

No where did I say that this was a funny thing but you seem to need a sense of humor transplant.

By the way, if iOS 6.0.2 isn't working for you on your home network you should test it on some other networks. If it functions well there you may want to look more closely at your home network. If it doesn't work there you might want to do a complete iOS restore on your iPhone and/or check for a hardware problem.

If there is some error in iOS 6.0.2 which is showing up on your network then, hopefully iOS 6.1 will contain a fix for you.

I just put my phone in airplane mode, then turned on wifi so that I know it is only using wifi and ran some tests here at work.  The speedtest app is working just fine, but when I go try to download books and other stuff things are running so slow its almost like it is turned off.

Also, interesting note:  I've had the phone turned into airplane mode for at least 30 minutes and just received a text message from a friend.  Went to click on the message and it says I can't send or receive text messages while in airplane mode.

Well, at least you can't send.. :-)

My situation is the same, it appears that I have an application throughput issue of some kind.  The speedtest.net app works ok, maxing out and showing good throughput.  However when I go to use Downcast, iCatcher etc the download speeds are just dismal (it is showing 50Mb files taking an hour or more).

Never had this problem on my iPhone3G, iPhone3GS, iPhone4, iPad1, iPad2 or iPad3.......hmmmmm, maybe I have an iProblem?

I always keep my os updated since using 4 until I got 6.0.2 with 5 then I have the exact same problem like most people.... But it started to connect a bit  further from router these few days at home maybe it's a good sign???
