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!

Ever since upgrading to IOS 8, including IOS 8.01, 8.02 and 8.1 I had the wellknown Wifi issue.

wifi speeds dropping from 120mbps to about 2mbps @ 5ghz in within a minute after connecting to the wifinetwork. often i couldn't even surf at all. but the wifi signal was always strong.

With every update i was hoping for a solution from Apple but it never came.


Tried everything that can be found on the internet.

Resetting the network settings.

Disabling "wifi networking" under Settings > Privacy > Location Services > System Services.

Reinstalling my Ipad from scratch

Used different routers and different setups.

Automatic ip's and fixed ip's and different dns servers just to be sure.

Nothing worked. The only workaround is switching to a 2.4Ghz network.


So i was doing some tests and found THE solution, but i don't like it all.

One of the biggest changes in IOS 8 is the ability to use airplay without a network. by using a wifi connection in combination with bluetooth.

And here lies the problem.

I disconnected al my Airplaydevices from my network. Denon AV-amplifier AVR2113, Pioneer wireless speaker XW SMA3 and an airport express.

Et voila... My Ipad is back to normal. fast... no very fast internet connection and stable as ****. Just like iOS 7 was.

Working with it for a couple of hours now without any trouble at all.

But do i connect one Airplay device to the network the wifi is not stable anymore and extremely slow again on my ipad air.

My Macbook running mac os x mavericks doesn't have these issues, neither does my iphone 5S. and they are also on the same 5ghz network.


So I can create and recreate the issue and create a work around... Apple please come with a solution that makes me able to use airplay an ipad (on ios8) on a 5ghz network! like in iOS 7!!!!

After spending nearly $200 to get our internet service provider to debug the problem it all was from one simple setting! You need to change your Wireless Network Channel from Auto to either: 1, 6, or 11. Try setting the Wireless Network Channel to 11 first and the make sure you apply the settings. Your router will then reboot and everything should work!

If you guys are seeing wifi issues, try this option & see if that works.


I was having WIFI slowdowns with IOS 8.0-8.1.x when bluetooth was enabled. If I disabled it I would have broadband speeds.

With IOS 8.2-8.3 I can have bluetooth enabled but when I stream audio to a bluetooth speaker my broadband WIFI speeds drop to dial-up speeds.


Disabling bluetooth is a workaround, not a resolution but thanks for posting your results. Everything that people contribute to this discussion hopefully is being looked at and researched by Apple.

Which contradicts what you just said above.


Thanks for the enlightenment.

No it doesn't contradict. If it was hardware my problem would have existed exactly the same in IOS 7.x, IOS 8.0, and IOS 8.2 and up. If it was software everyone would be having the same problems. I still think it's a combination of hardware in some devices and IOS8.x.


In IOS 7 I didn't experience any WIFI slowdowns.

In IOS8 my WIFI when bluetooth was turned on, not even connected to anything was at dial up speeds. If I shut off bluetooth I'd get great WIFI speeds.

In IOS8.2 and up my WIFI has dial up speeds ONLY when I'm streaming to bluetooth speakers. At least I can have my bluetooth turned on. If I don't stream audio to a bluetooth speaker WIFI is great. Once I stream WIFI turns into dialup speeds.


Apple has contacted me twice because of what I've been posting on this forum. From the tech that contacted me he said top engineers have been assigned to my ticket. I think Apple has worked out some of the bugs in IOS 8.3 but I feel some still exist especially with some symptoms I see personally and others have been posting here.

To me and anyone else using logic and deductive reasoning

Hmmm. It works just fine with one hardware router but not with another hardware router. However, your logic and deductive reasoning tells you that the problem is with the IOS software. Amazing!



Apple has admitted this - in case you forgot.


iOS 8.3 - Release notes

Wi-Fi and Bluetooth fixes

• Addresses an issue where some devices disconnect intermittently from Wi-Fi networks


It does not happen with all hardware router but Apple admitted it happens.


And same router works perfectly with other phones.


So logical deduction - Some (or may be all?) iOS devices have issues with some hardware routers.

So your point is that the issue has been resolved and Buffalo_DanK is imagining his problems!

If you read Release notes most places it says "Fixed" but for WiFi issue it says "Addresses"


So depends on what Apple defines "Addresses" as.


In my case I had issue - I tried with 2-3 routers. Finally found a router which fixed my issue. It still drops WiFi once in a while but auto-connects within 10-15 seconds.


So overall it ascertains and proves my belief that iOS 8+ does have issues with some routers.

To anyone having Wi-Fi connectivity issues:

Please see my post directly above. As reported by David Shanahan, Apple's DiscoveryD networking routine has been blamed for the Wi-FI problems some are having with both iOS 8 and OS X Yosemite. DiscoveryD was introduced with iOS 8 and was not present in iOS 7 (nor in Mavericks). I recommend that those interested first read the article Shanahan linked, but of more importance, on June 30 Apple released an update to OS X (10.10.4) and replaced DiscoveryD with its former routine mDNSResponder for "improved networking reliability". Details can be found here:

http://www.macnn.com/articles/15/06/30/new.update.excises.troublesome.discoveryd .service.much.more.129295/


I updated my MacBook Pro to 10.10.4 and I am having no Wi-Fi issues whatsoever, in fact I can keep Bluetooth and AirDrop enabled and still retain excellent download speeds. With iOS 8.4 (which still uses DiscoveryD) my download speeds on my iPad and iPhone degrade to less than 1 Mbps if I turn Bluetooth ON. The article above does not mention when DiscoveryD will be replaced with mDNSResponder on iOS, hopefully soon.

I don't have any other Apple products just the iphone 5? And since I updated it to iOS 8.4 my wifi connection problems gotten worst? Tried doing a fresh update again but it's still the same. Info? iPhone 5 updated to iOS 8.4, wifi issue, lag or dropped out of network, sometimes wifi signal is gone going back to 3G/LTE after a few minutes switch Back to wifi. Same prob. over and over.


BrnB, the problems you describe have been experienced by many on this thread. There is a known issue with the networking routine in iOS 8 which affects a subset of users. Apple is aware of it, they have been in contact with many here (me included) and collected logs. You could try turning Bluetooth OFF which has helped some but don't hold your breath. iOS 9 is scheduled for release in the fall and hopefully will solve the issues.

So if it's not an IOS problem, what is it?


Please note my post on page 206. As I mentioned, Apple used a networking routine called mDNSResponder in previous versions of iOS and OS X. With the advent of iOS 8 and Yosemite, Apple switched to a new routine called DiscoveryD which has been associated with some of the Wi-FI issues reported here. DiscoveryD was not used in iOS 7 nor in Mavericks. On June 30 Apple released an update to OS X, 10.10.4, and replaced DiscoveryD with the former mDNSResponder for "improved networking reliability” as listed in their release notes. I updated my MacBookPro to 10.10.4 at the time and I am pleased to report that I have had no Wi-Fi issues whatsoever. iOS 8.4.1 still uses DiscoveryD. According to Apple, iOS 9 will be released in the fall and hopefully will include Wi-Fi improvements as well.

Let's see what Nick reports back on when he turns off Airplay devices and Bluetooth at home. Maybe the reason he sees no problems at work is because a corporate environment are not going to have things like Airplay to trip his phone's connection up. Hopefully he can eliminate these as possible causes - if it does improve things then at the very least it's a workaround until iOS 9.


I can only speak from my own experience, didn't have too many issues in wifi hotspots but at home across several access points I have setup there were some strange behaviours going on. Switching off Apple TV and Airport Express made everything work fine. It wasn't bad enough to constantly switch them off. But it didn't affect all our devices, 1 iPad mini and a third gen iPad was fine whilst my 5S and another iPad mini struggled to consistently display airplay devices and was slow accessing apps that allowed browsing of NAS drives within network, not too mention occasional slowing throughput on speedtest(ookla) app. So not all devices doing the same thing. And of course now I have iPhone 6 plus to replace the 5S and now see no issue whatsoever on this. It's a horrific troubleshooting exercise for Apple I know, like looking for a needle in a haystack but all people can do is hope for iOS 9.
