Q: iOS 8 Wi-Fi problems

WI-Fi problems on iPad Air, iPad mini with Retina display and iPhone 5S after upgrading to iOS 8.

Typical results from OOKLA Speedtest before upgrade: Ping 17 ms, Upload 21 Mbps, Download 4.4 Mbps

Typical results after upgrade: Ping 39 ms, Download 2.9 Mbps, Upload 0.47 Mbps

iPad 2 with iOS 7.1.2 get 15 Mbps download and 4.4 upload on the same network.

Resetting network settings on the iOS 8 devices did not improve the performance.

Changing band on the router from 2.4 GHz to 5 GHz did give me back the speed on all devices.

However the speed occasonally drops on the iOS 8 devices, and the signal strengt can go from full til lost connection without moving the devices.

Also sometimes the Wi-Fi SweetSpots app report 0 mbps when the signal strenght is indicated as full and then suddenly go up to around 58 Mbps again.

It is almost like the device is trying to use cellular network that I do not have on the iPads before it suddenly switches back to Wi-fi nettwork again.

I am thinking about going back to my iPad 2 with iOS 7.1.2 that is working perfectly until the Wi-Fi issues are resolved.

 

Any help will be very much appreciated!

    It's been about a day since I installed 8.1.1 on my iPhone 6, but, so far, Wi-Fi seems to be considerably more stable and faster. I'm not sure if it will last, but, thus far, it's definitely better than previous versions of iOS8.x .  For those of you on previous versions, it couldn't hurt to upgrade and give it a shot.

    Join the club. iOS 8 was the common denominator for most all of us. Many are just looking to see if there's anything they can do that might help them coexist with their iDevice while they await an iOS update solution.

     

    Others, like me, ordered competing handsets Sunday afternoon via FedEx 2-day.

     

     

    You should clarify and say "Other trolls, like me, ordered competing handsets Sunday afternoon via FedEx 2-day."  All of your idiotic posts pretty much confirm that you are nothing but a droidbot and should be ignored.

     

    I would suggest that you focus your attention on the multitude of threads that discuss the numerous problems with Android phones, and stop giving bad advice to iOS users, but I'm sure you won't.  This board doesn't provide an emoticon to give you the finger, but use your imagination... if you have one.

    Thank you Stanky, that was badly needed......

     

    As a developer for both previously mentioned platforms, I can guarantee you that there are an equal number of glaring problems on the other side of the fence.

     

    As a side note, although the 8.1.1 update 'says' it's primarily for iPhone 4S and iPad, I can also guarantee you that it fixes a significant amount of WiFi issues on ALL IOS 8 devices, including the 6 and 6 Plus.  I personally worked with Apple on two specific issues, and continue to do so.

     

    One thing everybody should keep in mind:  none of these mobile platforms will EVER be bug-free!  The systems are far too complex, and it is literally impossible to test them 100% (not enough monkeys in the universe to get that done).  Granted, these bugs were a bit more obvious and should have been caught, but every OS out there has issues like this from time to time.  One thing's for sure, these bugs ARE being addressed.

     

    As an example, just check out 'audio latency problems' on the 'other' platform.  Bug initially filed in 2009..... not fixed yet......

    wifi issue seems to be fixed on my iPhone 5S since 8.1.1 installation.

    It was a long wait but at last i can expect to be able to enjoy my iphone like in iOS 7 days …

    FWIW, after installing 8.1.1, I've not noticed any wifi connectivity issues on my 5S handsets. For the potential benefit of anyone who remembers my initial post, I was able to flash the AC66U back to an Asuswrt-Merlin build and the wifi remains stable.

    NNo real change for me with ios 8.1.1. I don't have dropping or connecting issues. But it's really annoying that every time I sweep up control centre and then run a speedtest (Ookla app) the throughput is cut by two thirds. It recovers if I quit the app and run again but I can recreate the problem every time by doing this. I can live with it but it's garbage when i know ios 7 doesn't do this. It only happens on the 5s but not my iPad third gen. It's something in control centre and it's implementation on the iPhone i am sure. Perhaps the presence of AirPlay is causing it too. I have Apple TV second gen and an airport express in my AirPlay list. I think the fact the icon displays itself in control centre is maybe contributing to the issue. Of course I have let the guy in apple care know but I don't hear anything back. Its been a disastrous ios, so many bugs. I only updated to it because ultimately I hope to get apple watch and I guess you need ios 8 to use it conjunction. But now I very much doubt I'll buy it unless I see radical improvement from apple.

     

    why do they release so many iOS versions every single year to couple with hardware release. They should give an iOS longer cycles and time to mature. By the time they get ios 8 going better (if ever) they will thrust ios 9 on us and throw more bugs into the mix. I think their QA testing is poor but also the rapid release of ios also too blame as they are unable to test efficiently and rush out release. Kind of pointless having betas if they don't listen or address issues reported. They just go through the motions and release it anyway

    Well now more than two months and 4 updates since IOS8.0 rendered wi-fi unusable on my iPhone 4S and still no improvement after the latest 8.1.1. Ever the optimist I keep hoping the next update will do the business, but the only luck I'm having is not busting by cellular 1Gb download limit each month by not having wi-fi.

     

    I keep checking back here and viewing lots of well intentioned and no doubt well meaning potential solutions involving flashing router firmware, changing SSIDs, altering frequencies etc., but these miss the point. Wi-Fi worked flawlessly on my 4S on IOS 7 (and continues to do so on ALL my other devices) but has not worked properly since IOS 8. The upgrade caused the issues.

     

    Apple customers should not be expected to mess around or replace their networking infrastructure just to restore service due to a faulty iPhone operating system, although the reason why people are doing this is perfectly understandable, they are frustrated and clutching at straws to get their devices to work properly.

     

    I haven't given up on Apple just yet, but I won't consider upgrading to a newer model as a fix for wi-fi being trashed on my 4S by an IOS upgrade.

    Don_wan, the replies in this thread don't miss the point. If we stood silent, Apple and others would think there was nothing wrong & no tweaking would be required. The iOS 8.1.1 update did work for me, but so did switching to an "AC" router as well. I've concluded that iOS 8.1 did not play nice with "N" routers (801.11n, as iOS devices running 8.1 had no problems with 801.11a/b/g or 801.11ac routers. The new update addressed it on my end, and others.

     

    Yes, iOS 7 was perfect but as you know, Apple likes to update their software but it seems they are rushing them out nowadays. Perhaps they will learn there lesson after the iOS 8+ fiasco.

     

    Hope you do get your issues sorted out.

    It wouldn't let me start a new discussion for my question regarding the new iOS 8 software for iPhone 5s, so I'm posting it here.

     

    After upgrading the software, I found that the health app was tracking my activity even though it's not open or running (and it's very inaccurate).  I wasn't able to delete the app the standard way (holding the icon until it shakes and hitting an 'x'), but was wondering if there is either another way to delete it, or a way to prevent it from collecting this data - I wasn't able to find anything in preferences, privacy or within the app itself.  Suggestions??

    There are so many trolls creeping this board, it's ridiculous!  Anyway, since I upgraded to 8.1.1 on my iPhone 6 2 days ago, Wi-Fi has continued to work flawlessly.  As you mentioned, the release note did indicate that the update targeted the 4s and iPad, but I think it might be Apples way of addressing this problem without admitting to the issue.

    IMO, the wifi issue is definitely something caused by the interplay of IOS 8+iDevice HW and certain routers. I can report 8.1.1 did NOT fix the problem with my iPhone 5S wifi. I have a Linksys EA3500 router (dual band N). When the 5S was on IOS 7 it had no wifi issues, but upgrading to IOS 8.x (and future updates) resulted in the 5s being very unstable with wifi. The problem is always the same. Somewhere between an hour and 24 hours, the phone will stop communicating with the router. It will show wifi, but just hangs as if it's not connected and eventually times out--- and it will stay that way unless I toggle the phone's wifi or reboot the router.

     

    Believe me when I say, I've tried every "fix" from every board on both the phone and the router.

    iphone: tried every suggested setting tweak I could find, did a clean reinstall etc.  No help

    Router: Ditto, plus FW update, linksys tech support. No help.

     

    The ONLY solution for me has to been to add my old Linksys WR54G router as a dedicated access point for the my 5s. All my other iDevices (Air2, wife's 5 and mini) work just fine on the EA3500 as do my other devices (laptops, streaming devices, printer). As a test,  I even configured the EA3500 to act exactly like the problem free WR54G but the 5s continues to exhibit the wifi problem with the EA3500. I had hoped 8.1.1 would fix it. Worked fine last night on the EA3500, but the wifi again hung up this morning.  Back to the WR54 for the 5s.

     

    So there you are. It's IOS 8 vs your router. Some tweaks, phone or router, might fix your problem -- as has been reported. It depends on your router and/or iDevice model. Or every tweak possible may not help at all -- as has been reported. Again, depends on your router and/or iDevice model.


    I reported this Apple in early October. It amazes me that Apple cannot figure this out.

    At least now I know why my iPad would always drop the 5G/N signal and link to the regular G signal.  My 4s lapped up iOS 8.x.x like a champ but the wifi is still spotty.  It's such a beautiful, little phone and I wish Apple still sold it.  I gave the 4s away yesterday to one of my paralegals.  I had replaced it with a Nexus 5 but screw Android and its customization -- I can't find anything or make it stop vibrating (although I have two android tablets).  So I solved the 4s issue by buying a 5s -- those 6s are just too big for my wee widdle hands.  The 5s has had no issues other than I never get Verizon's LTE right here 2 miles from Atlanta; Touch ID is great.  My iPad 3 choked on 8.0 so I reverted to 7 in time.  I took a leap of faith and 8.1.1 on the 3 now works fine.  A little hesitation but whatever, I'll probably end up giving it away to another paralegal.  My Air 2 has been excellent right out of the box except for Dodocase not selling a case for it yet.  Again, Touch ID is the bomb!

    Stevehc2, I've concluded after several "fixes", SSID renames, settings tweakes, iOS device exchanges........that the WiFi radio hardware or iOS 8+ software is not completely compatible with "N" routers. It seems to have no issues with 801.11a/b/c or ac routers.

    Wow ....Thank you so much ....This actually works !!!!!

    I've logged into my router and changed the wireless mode to b instead of n and now it works like the IOS 7 days.

     

    Thank you so much !!!!

    XLT, you're welcome but you will be transferring at slower speeds, just so that you know. See the differences between 801.11b and 801.11n via a Google search.


    Apple still has to get this fixed and it seems like a recall might occur in the future if these issues are hardware related. There's no reason why our devices can't stay connected to "N" routers unless the WiFi radio component is defective on all of the newer units. On an iPhone 5 or older iPads, it's the unfinished iOS 8+ software that may not quite be there yet.
