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!!!!

8.0.2 on iPad Air worked for me (unable to connect since Tuesday). After updating new version had to reset modem. Then on iPad - General - Reset - Reset Network Settings then went to Wi-Fi and selected network again - all works good here. Only issue is GroupWise Calendar app - opens and closes right away - even after installing again. Things are looking up - at least connected to wi-fi again.

All my wifi issues have been fixed so far. This is on an iPad Air, 2x iPhone 6's and an iPad Mini.


Here's what I did if you missed it:


1. Go to Settings > General > Reset > Reset Network Settings.

2. After it has rebooted go to Settings > Privacy > Location Services> System Services > Wi-Fi Networking - turn it off if it's on.

3. Reboot your device and then go to Settings > Wi-Fi and re-enter your wifi security key.


Viola! As I said this has worked for me so far on 4 idevices and fingers crossed it'll work for you too! 🙂

Its quite possible that there is more than one problem with wifi. However what I am seeing is not related to DNS or any of the other network settings.

I have my own DNS server, and multiple devices are using it, so I know its working just fine, and much faster than the Google public DNS.


What I see is that if I ping the access point, which is a professional AP, not part of a domestic router, with any device EXCEPT my iPad I see a ping time of less than a mili second. Which is what you would expect.


Now, if I perform the same test from the iPad, the ming time is more like 30ms. Being generous, that is 30x more. Watch those ping times and you start to see outliers, with pings in the 100s of ms,


After a few hours, most pings are in the hundred ms rang, with outliers into seconds. Leave it a bit longer, and you start to see packets dropped.

Eventually there are more packets being dropped that are being returned, this is the point at which things become totally unresponsive.


You really have to look at ping times, Speedtest isn't a good indicator, until you get into the end stages and nothing really works any more.

Speedtest is designed to test throughput over wide areas. The way you do this is not to request a block of data and wait for it to arrive before asking for the next, you have a "window" of requests - basically, you request N blocks of data, and as each arrives, you send a request for one more. This ensures that there is a constant stream of data arriving, as fast as your network connection can deliver it. This is done to make the test independent of network latency. That will include latency in your wifi connection.


Looking at the round-trip time of individual packets, going over that few feet between your iOS device and your access point is what really matters.


If you have a slow ping, DNS is not involved, and honestly, any difference due to the band or MIMO is not going to account for 30ms, which is enough time for a packet to go coast to coast and back in the USA.

My 5s suddenly started dropping packets like crazy. 2.4 GHz network disappeared and 5 Ghz kept disconnecting. When connected I was getting 6 Mpbs down and 3 up. Rebooted my 5s and everything started working again and got 29 Mbps down and 11 Mbps up on 5 Ghz channel.


Getting annoying having to reboot periodically to keep a stable network connection.


I've already restored iOS 8, reset network settings and reset all settings. I'm now on iOS 8.0.2 and nothing has changed.



For what it's worth, over at bugreport.apple.com, there's a Wifi logging profile you can install which is supposed to log Wifi. When you hit the problem, you sync with iTunes to grab the log and then you can submit a bug with Apple. I'm doing that as soon as the problem comes back. Since it requires a reboot to activate logging, it needs to be done before the problem occurs.

Update - I opened a case with Apple this afternoon and spent quite a bit of time doing some troubleshooting on the three iPads in the house. Long story short, the problem (at least for me) appears to be that IOS 8.2 has difficulty with 5G channels via wifi. After many tests, restorals, etc - we can replicate that all works fine on 2.4 ghz networks. Changing back to the 5G is where things start to go wonky.


They have a case opened and will be escalated to their engineers. Would recommend that everyone take the time to open a case with them to make sure that they get the message.

All,


i had the same problem as all of you here, after many long trial and error go I have fixed my iPad air. The problem does sit with the device its self but the fix is actually with the router, most routers now run a 2.5ghz frequency and a 5ghz as a dual outgoing signal, the iPad cannot handle receiving both if these frequencies and freezes after a short while after getting confused.


i had to go into the wifi router settings and simply turn off the 5ghz signal and it's all working perfectly again some 3 days on.


i had tried every re boot, re build and apple even gave me a new iPad but this simple fix was actually all that was needed. Really hope this fixes you issues guys and good luck.

While we're all frustrated with Apple's screw-up of IOS 8, I see the wifi problem varies significantly between users. Some have gotten their devices to work by going through the seven or so reported possible workaround solutions. My thinking is instead of waiting for Apple's fix with 8.1 while having a device that's dead-in-the-water, it might be worth to keep trying a few setting change combinations.


It seems many of the reported issues point to the 5ghz channel setting on the router. I also noticed that those with Apple Extreme routers may have different results than those with other routers. My thoughts are to try a few changes on your router's channel and other settings, and also recommended IOS device settings changes until possibly the right combination might work for you. It's looks like a complicated glitch involving the handshake between the IOS device and the router. So I say keep trying.

Update: per next post, I see Apple just released 8.1. Hopefully no need to tinker now that that's out.

I have an iPad 3; after upgrading to iOS 8.1 I experienced wifi connection constantly dropping. Any suggestions I read did not help (location services, reset networking etc). After reading about Angry Birds and Game Center, I logged out of Game Center in the few games I play (not Angry Birds btw). Since then (3 days ago) wifi has worked fine. It's not ideal (having to click away the Game Center login popup when I want to play a game) but at least I have a working iPad again.

Dan, try Linksys's suggestion in my reply above. Create two separate SSIDs in your new AC router (if that's what you got) and have your iOS 8.x devices connect with the 5GHz SSID on Auto channel mode and report back here after a few hours. It worked for me.


The iOS software does not play nice with "N" routers for some reason.

Nov 18, 2014 11:28 AM in response to E-2043

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.
