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!

    So, having previously commented on the terrible problems I had been experiemcing on both my iPhone 5 and iPad Air immediately after installing iOS 8 I am pleased to say that following the installation of iOS 8.1.1 last night they were instantly corrected.

     

    TOday my iPhone has only lost 17% of its charge after being taken off the charger 12 hours ago compared to 80% for the last couple of months. My iPad immediately connected to my home router last night and despite accessing all the apps that, hitherto, have killed my wifi access, all is still working fine.

     

    Today is ay is the first day since updating to iOS 8 that both my iPad and iPhone have worked properly. I feel equal measures of relief and annoyance and, suitably chastised, I will be far more careful in future when installing future iOS releases.

    Apple now has possession of my iPad 3 that was experiencing the "Incorrect Password" issue, slow wifi speed and signal when I could get it to connect on my home router, or, would work great with our system at work, after updating to IOS 8. Quite a broad spectrum of info for them to analyze. They recorded all my router info, settings, etc. as we did troubleshooting on my home PC via screen share for quite a while. I loaded the wifi logging profile on my iPad direct from Apple, and tried multiple wifi systems both with, and without success, sent them all the logs, as well as a detailed written log on what I was trying to do and where. Hopefully it will lead them to a root cause that will help us all.

     

    As I said before, is this what I want to do with my products that I've paid for, is be their unofficial test subject? No, not really, and Apple knows that. However, if I have a key piece of equipment/information that can help break the case and help others in the process, I'm more than happy to help.

     

    This all transpired from this forum. I DID NOT contact Apple, send them hate mail, am not an Apple employee "poser" or anything. I just posted on this forum what problems I was having and was looking for a possible solution to fix my once almost flawless iPad 3 on IOS 7. Apple initiated contact with me, was very professional, courteous, helpful, and spoke perfect English. (No harm meant to non-English speaking folks on here.) Of course the reps I spoke with wouldn't say their stuff is broke, it's Apples fault, or anything, and I didn't I ask. That's not the reps responsibility, nor are they themselves going to really know. They are a tool to gather information to pass on to the engineers for further review.

     

    Now, I know my experience is not the normal for many on here, but it is proof that Apple is concerned for it's product, monitors this forum, and is taking steps to try and possibly remedy the situation. The more information of symptoms that they can gather on these forums I'm sure is looked at and taken into consideration, while all the complaining is in the way and bypassed. Several of Apple's beta testers have posted on here, and given heads up that 8.1.1 was out and being tested a while ago, was targeting specific issues, but was not the cure all for all devices wifi.

     

    I've been impressed that a large, world wide corporation, contacted me, the little guy, when they have much larger, corporate customers out there to worry about. I own Windows and Android products as well, and highly doubt that any manufacturer of their products would have ever contacted me directly regarding tech support, on a three year old device that has been superseded several times.

    I am having the exact same issue with iOS 8.1.1 on my iPhone 6.  Wifi gets disconnected several times when watching anything on Netflix, Hulu Plus, Amazon Prime, and YouTube.  Basically anything that plays videos.  Also, I continue to get the "incorrect password" message when I type in my correct password for my wireless router, after the phone has disconnected from the wireless router.  My wife has the same phone (iPhone 6) and has the exact same issue.

    Nothing was wrong with my old iPhone 4s with iOS 7.1.2 or my wife's iPhone 4. They never disconnected from any wireless router or wifi signal.

     

    This is software and/or hardware ***** as of right now and needs to be fixed.

    After trying a lot of workarounds I've found a workaround that consistently works for me which is

     

    1- unplug router

    2- make sure no other device is connecting to your router  (you can turn them off or turn off their WiFi)

    3- plugin the router and make sure your iPhone is the first device to connect to the router

    4- connect other devices

     

    as long as your iPhone/iPad is the first device to connect to the router after a reboot it will stay connected as long as you don't manually disconnect WiFi and switch to data(3g/4g) and back to WiFi again.

    I have done the steps you provided and it does not correct the issue.  Below is the message it gets quite often when using Netflix, as I do not want to use my cellular data to watch videos/movies.  A similar error message when using Hulu Plus, Amazon Prime Instant Video, and YouTube.

    Every iOS 8 update I visit this page to check if Apple finally fixed all the WiFi issues.

     

    Its a surprise that Wifi stills annoying iOS users. What I cant believe is how Apple still don't fixing an issue with the MAIN CONNECTION between an iDevice and the rest of the World.

    If I recall, one of my first experiences with an iDevice was an iPhone years ago that couldn't join a network. I changed the SSID, the name that the router broadcasts, so that it did not contain any spaces. If your SSID has spaces (or special characters??) maybe you could remove them or change the name altogether and try again. I feel like I'm really reaching here, but of you've tried everything else, it might not hurt. Come to think, I ran into a similar issue on a Windows box a couple years back that (short story) "required" an SSID change at the router. I'm pretty sure I'm not making this stuff up. ; )

    Also, if your router operates at both 2.4GHz and 5GHz, it's usually best to establish unique SSIDs for each. It's also *normally* more reliable to have the 2.4GHz side at 20Hz (not bonded at 40Hz or "auto"). Keep the 2.4GHz off of any channel other than 1, 6, or 11, despite how counterintuitive that may be.

     

    Note: I really want to help. I've suffered iOS 8 wifi problems of my own and posted on this thread previously.

    One last but:  If possible, don't let router respond to WAN ping (block WAN ping / block ICMP ping), disable UPnP, disable WPS / QSS...you can then probably rule out any common attack that might be affecting routing performance.

     

    sorry if this doesn't apply to you, but it might be useful to others

    iI'm glad it resolved the issue for you. What you have to remember is we didn't have any issues before so after an update made by a third party we have to mess around to get things back to the way they were? This really doesn't make sense to me.

    WQuell well well I for one didn't have a problem before IOS 8 came along. What else could I blame. I am unsure why we are running around trying to solve their mess?

    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.

    Alongside a release of Xcode 6.2 with WatchKit tools for the upcoming Apple Watch, Apple today posted its iOS 8.2 beta for developers. The release, build 12D436, follows the release of iOS 8.1.1 to all users yesterday with fixes and performance improvements for iPad 2 and iPhone 4S users.  So according to Apple 8.1.1 wasn't to help new devices but to help ipad 2 and 4s. There is no mention of performance of other devices also this new version is so they can help Apple watch. What about the current problem?

    My 4s has had wi-fi issues for some time now.  Another thread said it had something to do with a worn thingamajig that iOS 6 didn't mind but iOS 7 has greater error checking.  Currently I sit about 4 feet from my router and I have one out of three bars running 8.1.1.  The 4s is three years old and was having other issues so I bought a 5s two weeks ago.

     

    I put 8.0 on my iPad 3 but there were scrubbing issues on videos so I reverted back to 7.1.whatever back when you still could.  I bought the Air 2, which is crazily faster, and it also had some scrubbing issues but not as bad as the iPad 3 had.  Maybe because the 8X chip lets you get past errors faster?  Back in the '90s we would add RAM to computers just so they would "reboot faster" since Windows 98 always shutdown every so often.  This was described as a feature that told us when were were working too hard.

     

    These iOS problems are not bugs, they are new features.

    IOS 8.1.1 fixed my wifi issue with Angry Birds on an iPhone 5.

     

    Battery seems much better too!

     

    THANKS APPLE!
