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!!!!

this doesn't turn your WiFi off,,it just disables a setting that seems to be getting in the way of normal connection speed!

Well, I may have found a solution that worked for me. I should add a caveat that I unfortunately installed iOS 8.0.1 this morning and it killed my Touch ID and cellular network. So I had a useless phone all day long at work. I got home and after a hour of frustration, I was able to get 8.0 back on my phone and everything is working again. So I don't know if it's coincidence that my WiFi is working great again after I wiped my phone and reinstalled iOS 8.0 (I have an iPhone 6+).


But before this I was having the same WiFi issues as everyone else. I've been following this forum for a couple days now and have tried some of the suggestions, and they have appeared to work for me (at least over the last hour, and before hand I would get good speeds for 5 minutes and then they would die). Here is what I did:

1). Switch my security in my Netgear router from WEP to WPA2

2). Use the OPEN DNS numbers in my WiFi settings on my iPhone 6+ (I used 208.67.222.222 and 208.67.220.220)

3). Switch the 11N channel on my router to 149/5.745GHZ


I've been running OOKLA speedtest for the last hour and have been consistently getting 25mbs and before I was getting closer to 5. I know some of these solutions have worked for some people, so hopefully you might find a nugget in there that makes your home network finally work the way it used to on iOS 7.

After I got used to that everything is working with Google DNS I tried switch back my default DNS on all 5 devices. All ios devices have been up for 10 hours without any problem.

My current settings are:

1. ios Location service / Wifi networking OFF

Apple router:

2. Reset all settings and configure as new

3. Only WPA2 encryption

4. Both 2,4 (channel 3) and 5GHz (channel 48) are running on manual mode.

Restart all devices, router and forget network and enter passkey again.

Compared to 7.1.2 with 8.0.2 I just changed 5GHz from channel 36 to 48 and encryption to just WPA2


Not sure but seems that 8.0.2 solved something what 8.0 brought out but not all the wifi problems aren't gone.

FINALLY I SOLVED THE WIFI PROBLEM AFTER INSTALLING IOS8. 🙂


As most most of you I faced big problems with wifi after installing ios8 On both my iPad Air and iphone 5 . The problem remained even after installing iOS 8.0.2 on both. My home network has the ISP router connecited to my Timecapsule 4th generation. Rebooting hundred of times both devices didn't solved the problems (both slow speed and sudden wifI hangs).


YeEsterday I solved the problem as follows:

- I asked first my ISP to reset my adsl line

- I reloaded my timecapsule settings backup file I have on my laptop (is an old year old backup file made when everything was working well)

- I did NOT reinitiliazed both my iDevices as apple support suggested


All my devices are now perfectly working since more than 24hours!


i think that reloading my timecapsule settings file was the key move. Clearly iOS 8 affects the networks devices, it's weird it's something I cannot explain but not works. My suggestion to you is either to reset your routerm at factory settings and male a fresh configuration or restore from a backup file.


Hope this help everibody.

Set my dual band router 5GHz to Channel 161 from Auto Channel resolves the slow Ping issue. So far so good!

Was ~60ms with 5GHz channel set on Auto, is below 20ms with channel 161. So far so good!

However:

My router crashed and I had to power cycle modem and router...
Now again connected iPad using 5GHz band and channel 161, let's see what happens now...

I just solved our iPhone 6 (iOS 8.0.2) wifi connectivity problems by upgrading to a newer wireless router. We had a Linksys WRT160n that we bought 3-4 years ago, and just today replaced it with a Netgear AC1750. Not sure if moving from an 'n' router to an 'ac' router did the trick, or if it was something else to do with the newer router, but I'm just happy these phones finally work properly. Now both our iPhone 6's, iPhone 4s's, Kindle, and desktop all maintain great upload/download speeds (iPhone 6 using the 5 GHz signal). I can watch Netflix and YouTube again! On the older router, everything but the new iPhone 6's worked. It's been a really annoying week. For a while there we thought we owned two bricks. Pffeww.

POSSIBLY A FLUKE FIX... a week in now and still getting max speeds on 5Ghz on iPhone 6+ 8.0 & 6+ 8.0.2 no dropouts and no slowdown.


Was having the exact same issue.


Attempted all all the fixes/workarounds stated above. Worked well for a few hours, then continued to get dropouts or slow speeds.

Connecting to 2.4Ghz was consistant, However, speeds were maxing out at 9.7Mbps down and 5.8Mbps up.


Last week I had to factory reset my router (netgear R6300) and re-setup everything for other reasons (pain in the backside really). Since doing this, both myself and my wife (both on iPhone 6+ 8.0 & 8.0.2) have been connected to the 5Ghz band averaging consistent speeds of 93Mbps down and 37Mbps up (our usual speed) without any issues.


I Held off posting on the forum as I thought it might have been temporary, but it's been about a week now and no dropouts or slow speeds.


Not it sure if I was just lucky with this, so far so good.


After the factory reset, I am using a different SSID with WPA-PSK + WPA2+PSK wireless security, everything else has been the same (Including other devices connected to the network)

i also reserved IPs for all devices on the network through the router (keeping all devices set to DHCP) but I had this set prior to factory reset.


Sorry for blabbering, just trying to detail everything I have changed In hope it might release some users frustration.


Not it sure if this will work for anyone else, might be worth a try until the release of 8.1 ?


Wish you all the best of luck!

My iPad Air is now working fine after making a router setting change. I recommend others give that a try. It's based on R.Crowden's recommendation to change the 5ghz setting. Either turn it off or make it "automatic" (in my case) if it's not already. I have not had a problem since and now always have consistent full connection speed. It required rebooting the router, which might be beneficial as well. Worth a try!
