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!!!!

I do agree that discoveryd is probably causing issues. I am not sure why it remained in iOS 8.4, hopefully it will be removed for iOS 9. I don't get wifi drop outs on my iPhone and throughput is reasonable. But ever since iOS 8 there are quirky behaviours. On Airplay I have Apple 2nd Gen and Airport Express (connected to hifi). I can swipe up control center on my iPhone and sometimes the airplay is there, other times it is not, or it may only show 1 of these devices and about 30 seconds later the other will finally announce itself. Sometimes they refuse to appear unless I turn off wifi on the iPhone and re enable it, then they faithfully show up. This never happened on iOS 7. And it never happens on my older iPad 2nd Gen or the iPad mini my wife has. I think there is something in the Bluetooth / airdrop / discoveryd causing issues on my iPhone. My iPhone has to have Bluetooth on all the time because I have the apple watch. I also like using an app for Western Digital 'My Cloud' to access my NAS drive. It was fine under iOS 7 but under iOS 8 on my phone it will be real slow intermittently navigating the folders, several seconds to load. But only within wifi environment, outside under 4G its all instant. So I think the airplay, discoveryd processes kicking in at home possibly cause this. I hope discoveryd is ditched and the old method is restored in iOS soon and these glitches go away.

There have been numerous suggestions, but none of them provide a permanent solution. When I have the problem I restart my phone, it will then work for a few days before needing to restart again.


Same with resetting & restoring, resetting network settings, restarting router, turning airplane mode on (then off again). Some suggest buying a new router, I haven't done this as I'm not convinced it will cure the problem and would rather not spend on something that may or may not work.


If you take the time to read through all the posts, this problem started with IOS8. When IOS8.3 can out it made things a lot better, but for me IOS8.4 was a retrograde step as the drop-outs go worse


Like elcpu said, there is a major release of IOS9 planned for September

Good morning, iDevice. Thank you for your post. I watched the YouTube video twice (notepad on hand) and I appreciate you posting it. As a summary (like old_chap's) the video recommends the following steps in this order:


1. Forget Network

2. Reset Network Settings

3. Reboot Router/Modem

4. Perform a Forced Restart

5. Change to Google's DNS

6. Under Privacy > Location Services > System Preferences > turn Wi-Fi Networking OFF

7. Restart the device

8. Restore the device

9. Wait for iOS 9 (interesting that #9 is waiting for iOS 9 !!)

10. Downgrade to an older version of iOS (impossible once the older version is no longer signed by Apple, usually a few days after a new release)

11. Go to an Apple Store


These are not bad recommendations (with the possible exception of 10 after a few days) and I recommend that all users affected by Wi-Fi issues try them first, they have worked for some. Unfortunately, for many others these have been tried over and over with no improvements at all (exception #9 for obvious reasons). Number 9 is eagerly anticipated by many here.


Thanks again,

elcpu

Wobbly, I have looked at the manual you linked (yes, the link works) and my own 2 cents follow.


The Huawei looks like a nice device. It offers 3 modes and you are likely considering it for the Repeater Mode (not Router Mode). Is that correct? If so, an extender or repeater can only "extend" whatever signal it gets at the point where it is connected to an outlet for power, i.e, if you place it close enough to the main router and at this point you are still getting a reasonably strong signal, the extender will "extend" or "repeat" that signal level further. If you place it far enough from the router such that the extender is only seeing a weak signal, all it can do is repeat or extend that weak signal. So placement is critical. Whether it will be of benefit to you or not is hard to tell. It could very well extend your signal further if your main router signal drops quickly from the point the Huawei is powered.


If your house was wired with Ethernet, a second AP connected to the main router by CAT 5/6 would be far preferable. That will provide additional coverage in a large house and this is what I have in mine. If you do not have Ethernet cabling, you could try Ethernet Over Power Lines Adapters instead like the one below:

http://www.amazon.com/Linksys-Powerline-Wireless-Extender-PLWK400/dp/B0087O6AQE/ ref=sr_1_1?s=electronics&ie=UTF8&qid=144…

TP Link and others also sell similar devices, maybe even better. I am familiar with the Linksys since I own one. I am actually "C", the reviewer voted "most helpful" on Amazon and I suggest you read my review there for the "good" and also the "caveats". When these units work, the work great!! and will provide a second AP at a far location with good strength. The only drawback is that they may not work across certain circuit breakers or sub-panels as I described in my review. Cisco who used to own the Linksys line (now Belkin) stated that they work 90% of the time - they worked in my case. I am not using this unit any longer in preference for another router set up as AP only behind the main router (would need Ethernet throughout which I have).


I am in Texas and I am able to buy from Amazon Prime with a 30 day return thus able to try any unit. If you can do the same you could try either of the above, I would recommend the Linksys first and then the Huawei - if they do not work, return them... They also make Ethernet Over RG6 Adapters if your home is wired as such.
