Why does iOS 8.0.2 not resolve the issue of WiFi connectivity with iOS 8 and the new iPhone 6?

Same for me. Sadly, 8.1 did not fix my WiFi issue on both my iPad mini and my iPhone 5S. Specifically, I'm still having a problem with WiFi throughput and idle connectivity with my cellular carrier. I'm painfully aware now that since the 8.x upgrade on my iPhone 5S, I've been exceeding my normal data usage over my cellular data connection where I've never come close when it was running IOS 7.x. I suspect the problem relates to the fact that my phone's WiFi constantly disconnects from the access point (router) and switches over to cellular, which results in my elevated data usage over my cellular carrier.

My wife and I both have iPhone 5S's. She is still on IOS 7.1.2 and I am on 8.1 now. We can sit them side by side and she has no issues streaming audio or video content whereas my iPhone struggles to connect and when it does there is choppiness and disconnects of the streaming application. On our iPad mini, when trying to connect to my Slingbox to stream video, it rarely connects any more now under 8.1. This could be an issue with either the device's WiFi or the app needs updating or a combination of both.

I've tried restoring the devices, setting them up as a new device as well as deleting the app's and reinstalling, but the performance does not change. Router rebooting does not help either. Under IOS 7, we were using the iPad mini in our master bath to listen to the news in the morning as we were getting ready for work. Now it just sits there as a decoration as its unable to stay connected to our WiFi under IOS 8.1.

We were hopeful that the latest update to IOS 8.1 would correct the WiFi issues as Apple indicated in the bug fixes, but alas, we are left with the same issue as before.

I encourage you ALL to at the very least copy/paste your situation you've posted in here to the FEEDBACK APPLE SITE

https://www.apple.com/feedback/iphone.html

This will ensure , unlike here, its heard by the right personnel.

This is simply a black eye for #APPLE .... I have been posting this issue for almost a month to social media sites as well as here, and the apple feedback link I provided - its a issue that needs addressed - clearly

my Router wont do 5ghz so thats not an issue and its same router I had before ios8 .. had NO issues prior ios8 , my data plan for Verizon can back that fact up as well. Literately to the DATE I downloaded the ios I can watch data skyrocket.

Cmon Apple, you can do better than this surely !!!??

Reading these posts, folks refer to new software releases as "upgrades". I hope y'all understand it's never an upgrade. Some of us can remember back all the way to the problem with 3.1.3. Overheating, people putting their phones in the freezer to get WiFi working again. Many many other issues when you load a new software version, very bad track record. General rule of thumb, unless your phone has a problem, NEVER EVER change the software. It's a hard lesson.

Same here... it's eating up my data and costing me $... is Apple getting paid by the cell phone companies to have this "blip" in their programming?! I have to keep turning off my cellular data at home to ensure my phone uses the wifi... ANNOYING!

Come on Apple, fix this!

Just got my iPad Air 2 and unfortunately the Wi-Fi Issues on my 5GHz network continue exactly the same as my IPhone 6 Plus and 5S. iOS 8.1 didn't fix anything!

TThis forum thread appears to have gone very quiet since Ios 8.1 was launched. Is it safe to take it that issues have been resolved?

not really, I still having issues with iOS8.1, but is a little better, now instead of turning the wifi off/on ~20 times in a day I just need to do it like ~10 times... and the wifi is slow in 2.4GHz, and worse if you connect in a 5GHz environment. I miss the 7.1.2

Its been 1 week since i installed 8.1 and i have not faced the wifi issue which i used to face before.

I refuse to download 8.1 until some sort of indication that it doesn't further complicate my problems.

A support tech suggested not downloading/updating for some time after any notification just to make sure these things don't happen.

I read somewhere around page 20-ish that one Apple user hasn't updated since 3.1.3

Aside from changing anything to do with my router settings I've tried all the other fixes suggested. I can't imagine it's anything to do with the router because it's been over a week and I haven't picked up a wifi signal anywhere, which includes home, work, and a hotel and conference center while I was traveling. I'm beyond annoyed and moving straight to furious, I've had a 250mb plan and never used more than 200mb because 90% of the time I'm within wifi range. Now I'm 2 weeks into my month and I've used 750mb! I have always stood by Apple and their glitches but this is ridiculous. I'm hoping that 8.1 fixes the issue for me, otherwise I have a really expensive paperweight because I refuse to use the phone until it's fixed.

Try this..

Let me share a work around that has worked for me So far.

I Had an issue with my MacBook retina since I bought it last year and was not able to connect to 5Ghz high channels. Specifically on the 40mhz band, if I changed it to 20mhz it was fine, but half the speed for moving large data files around on my network. So I went back to the low channels like 44 but these frequencies don't pentrate my walls nearly as well and I have a week signal in the yard. The high channels I can walk 5 houses down and still get great speed.

Well the mac is in getting the wifi card replaced after this still was not fixed with yosimite, so I went back to the high channels at home. It's funny how all apple stores run Cisco wifi on high channels but only in 20mhz band or maybe they would see this issue also instead to recommend I buy a apple wifi router.

So today I picked up the iPhone 6 and nothing but issues on 5ghz. Tested 2.4 and seems stable. So then I changled the channle back from 157 to 44 amd now I'm finally able to complete a backup to the cloud without the wifi dropping. My iPad 2 mini retina is fine and the iPhone 5s seems fine on the high channels.

so I'm starting to think this is something again with high channels and 40mhz bandwidth.

oh before anyone mentions it yes I did all the standard scripting trouble shooting, resets, clean restores and bla bla bla.

So my request to all having issues is.

1. What channel are you running? If above 100 have you tried the lower end of the spectrum? If not can you and report back if it also helped you?

2. If your bandwidth on the channle is set to auto, or 40mhz can you try setting it to 20MHz and see if that helps and report back?

TiP some routers are able to run wireless N on 2.4Ghz and still uses the auto or 40Mhz bandwidth option in the setting. If your having these issues on a 2.4Ghz router try changing the bandwidth setting to 20Mhz like I did with the 5Ghz router. It might help you also. If it works please report back and let people know.

Im just looking for a pattern and sharing what helped me, then asking you to try and see if it helps you.

i Know, I know. This is not a fix. It's a temporary work around and apple still needs to fix this wifi stuff with the 5ghz range. It's a shame that great hardware and design is not starting to get a bad reputation just because of the software issues and not testing properly before releasing it.

if your reading this apple, it the mix of stable software, with hardware, simplicity and design that sells your product and was the reason I moved over years ago for that stable BSD kernel.i support enough to tech issues 70 hours a week and didn't want to deal with it at home. I admire the movement to bring everything together across all your hardware to be the same simplicity and the free OS updates for the Mac the last couple of years. But truth be told even junk unstable software is not worth being free. Please fire the guy responsible for this testing before release, and yes I have an idea on who this guys is also. Can you say apple maps?

I don't have the time to this robustly, but I was having similar wifi issues on my iPhone 5S on 8.0.x and 8.1. I was easily able to connect to the 2.4 GHz wifi and keep the connection on my TP-LINK home router, but my Cisco E4200 2.4Ghz wifi would take minutes or more to connect to, or fail entirely, and when I was able to get it to connect, inevitably after unlocking my phone again it would have lost the connection, or show it connected but not be able to send/receive any data. I finally dug into my router settings and found the 2.4GHz network was set to 20Mhz only. I switched that over to be Auto (20Mhz or 40Mhz), and the iPhone was immediately able to connect. It's also maintained connection for the hour or so I've been running it now. So, not a robust fix...but worth trying if your router has those settings.

Considering this is somewhat counter to what Scott.J.D noted on changing to 20Mhz, it sounds a bit like there may just be various interferences between routers and getting the right configuration for your mixed 2.4/5Ghz environment might be a bit of trial and error...

Wyndairn, thanks for replying. I did confirm the auto 20/40 may work for the 5S and maybe and older Ipad that might not have the AC wireless chip.

i Chose to use 20 only because the iPhone 6 was trying to connect at 40 and that was causing it to drop. Or maybe it was my laptop that was trying 40 because it has a third antena and the iPhone only have 2 wifi antenas.

now that I think of it, it was because of my laptop. So if you happen to own a MacBook pro after 2012 (mine is mid 2012 retina) then you may have three amtemas and it will try to connect on 40Mhz and might fail.

Now the funny part is I have had my router set to only 40 for over a year. The laptop worked on the low channels this way. The iPad mini 2 retina never had an issue. The iPhone 5S never had an issue. When I got the iPhone 6, boom. Nothing but issues trying to stay connected. So I would say the issue with me and why I changed to 20Mhz has something to do with the drivers or the wireless A/B/G/N/ AC chip that is in the iPhone 6 or the latest iPad air 2. Maybe even newer released laptops also.

I Think wireless AC is still considered draft. Apple never used to out draft hardware chips in their systems until a few years ago. The problem with draft is its not finalized yet and does not have a real standard. Some manufacturers may be doing their own thing and some chips may be flawed, hopefully they can be flashed to be fixed or updated once a problem is recognized and resolved durring the draft testing. The wifi AC chip is new with apple and I personaky beleive its a software issue and hope they read these threads and work on resolving this. But then again a bug I found in iOS 7 mail client beta testing that I forgot to report is still in iOS 8.0.2. Not sure about 8.1 since I have not had it more than a day. But if they haven't found that bug yet they may never realize this one.

Open tickets with apple.

If you have a development account then please Report this in their bug tracker so it gets attention then they will hopefully look into this and fix it. I no longer have a development account since it was paid for from my company and I changed positions Or I would have reported this already.

Note: some of my above fact with antenas may be off since I have not made it to bed yet.

I work on iPhone problems all day (mostly backup and restore right now), so I collect a lot of the debugging logs. I saw a lot of networking error garbage on my 5S right after upgrading from iOS7 that was vastly reduced after doing a reset all settings (I wish I would have tried just Reset Network Settings first, so I knew if that worked alone.) (Reset All Settings can be found in Settings App -> General -> Reset -> Reset All Settings NOT Erase All Content and Settings in case anyone hasn't tried that yet.)

As weird as this may seem, I would love to take a look at anyone having this issue's iPhone debug logs. (Like I said, I do iPhone troubleshooting all day, so investigating and hopefully fixing a serious problem sounds exciting to me 🙂) If you want, you can contact me through my company's webpage: http://deciphertools.com/support.html and we can start looking at what kind of errors are happening while the wifi is acting up. You can mention my name directly, Kelly, so you know the message gets to me!

The debugging logs don't usually contain personal information, but the log collection instructions I'll send you create a file that you can peruse and cut anything you like from before sending it to us. And also, if you're on the fence about contacting us, you can follow the "testimonial" link on the contact page I sent, so you can see we're a real company helping fix problems 😉

This is a slightly different issue alone, it's not hardware related I think others already know that its software related and the only way to resolve the issue is to configure your router to wpa2 and on 2.4hz frequency, people sending there log reports to 3rd party is violating peoples privacy I would strongly advise those to not do it. log reports have important info and you wll regret it. I'm an technical engineer but you won't hear me asking for people's log reports contact apple and advise them a 3rd party is asking for your log reports and give them yhere details
