iOS 8 Wi-Fi problems

Yes the thread is out of control a bit. Some going off on tangents, those of us convinced ios 8 is at fault, those who do not. Fed up with the bickering. I think everyone needs to hold their hands up a bit. We will agree to disagree I think. Anyway my own personal view is ios 8 is having trouble with AirPlay so if you have any of these try unplugging them and see if it helps. I think maybe the Broadcom wifi chips are getting overwhelmed. The implementation in ios 7 was fine for me but in ios 8 it's not so good. Not dropping wifi so I am far better off than many poor souls but throughput is reduced at times and AirPlay discovery sometimes painfully slow. Like you I have tried all such as resets, restores, different routers. I have multiple non overlapping access points too and ios 8 gets in a mess with these too. Iphone 5s worst affected, iPad third generation a bit better, two iPad minis not terrible but it's not as it was on ios 7. We have loads of other devices too which cope brilliantly with our wifi. personally ios 8 seems a complex beast, probably apple trying too much too soon - who knows. All can do if it doesn't help for u is cling to hope that ios 8.3 and/ or beyond will be better

Like mentioned by some others, this helps with speed but not Wi-Fi disconnecting

And do not have TV, have turned off other devices (and in same room as router) but still loses signal

But other things I've noticed - almost certain this started when devices upgraded to IOS8, when my son comes round his Galaxy never has a problem. When daughter visits (iPhone 6) she loses signal just as in her own house. My wife has an old iPod witn IOS6, never any problems.

My iPhone 5 also suffers the same issues at work and when using public Wi-Fi

Whilst typing this the signal just disappeared & had to log in again.

Last weekend I dug out an old iPhone 4 running IOS 7.1.2. Swapped SIM with adaptor, put same apps. It worked perfectly everywhere

I realise none of this is a scientific test, but the only common factor seems to be IOS8

If you look through the comments (I know there are a lot) you'll see the problems being discussed are wi-fi dropping out for no reason.

You say you cannot connect at all, which sounds like something different. Is your phone in warranty, if so go to Apple for repair or replacement

If not try deleting phone & restoring as that may remove any bugs in settings

I see people having issues with many different iOS devices but I have not experienced any wifi issues on an iPad3, iPhone5 or iPhone 4S. The problem is exclusive to my iPhone 6 (AT&T).

I am sitting here at work right now and my iPhone 6 (iOS 8.3) is connected to an 802.11n wireless network through a 2.4GHz Cisco AP. If I let the phone go to standby for more than 25-30 minutes then click it on it will show as connected to wifi but there is no network access. The phone does not switch over to LTE when this happens; It just sits on wifi with no network access. So while in standby I get no notifications at all (like email). My iPhone 5 and 4S have never shown this behavior on any version of iOS 8. This is the same exact problem I have at home with a 2.4Ghz Netgear router and the same exact problem my mother has 900 miles away with her iPhone 6 (Verizon) on a 2.4Ghz Linksys router.

Just a hypothesis, but maybe the phone is having a problem with the group key update interval (when WPA2 generates a new key)? Normally the update interval is set to 1800 or 3600 seconds on home routers (30 or 60 minutes) and that seems to correspond with when my phone loses network access in standby mode. Tonight I am going to set the update interval on my home router to 43200 seconds (12 hours) and see if it loses connectivity during the night.

Also, it would be interesting to know if these wifi issues are exclusive to 2.4GHz, 5GHz or both and if the network is using 20Mhz or 20/40MHz channel width.

I am quite happy with my ipad air ios 7.12. I reverted it back from 8 as soon as I found it was working so bad with wifi and airplay streaming connected with timecapsule latest model. Now I need to use an ios 8 app but I know there is a big risk. Should I have to close my eyes and do It?

IOS 8 caused some problems for people including myself regarding my WIFI speeds. My problem was if my bluetooth was just on my WIFI speeds were as fast as dial up. IOS8.2 got better as I would only get dial up speeds if I was streaming audio to my bluetooth speaker. Rather than wait for Apple do something I wiped my iPad out and that gave me much better results but I can still see a decrease in my WIFI speeds when I'm streaming audio to a bluetooth speaker. Some people here have had good luck with IOS 8.3 and some have not. An example of this is me where some APs would keep prompting me for the password (a topic discussed a lot here before IOS 8.3 came out) and when I upgraded to IOS8.3 that problem went away for me but not some others. Some people said that IOS8.3 broke their devices.

All of us here don't think the problem is just with IOS 8.x versions. We're convinced it's a combination of IOS 8.? and something else but we don't' know what that something else is as not everyone is having problems like we are.

What I would recommend since I've seen improvements when I wiped my device is consider upgrading, wiping your device, and adding all of your apps back. I know that sounds odd but like I said I saw improvements in my device after I wiped it. I an't explain why. All of these issues are all over the place so no one can really tell you if it will work or not but if you upgraded to IOS 8 in the past and had issues then there is a decent chance that it might still act funny with IOS 8, or not.

Below is a list of things fixed in IOS 8.3 for WIFI and Bluetooth.

Wi-Fi and Bluetooth fixes

• Fixes an issue where you could be continuously prompted for login credentials
• Addresses an issue where some devices disconnect intermittently from Wi-Fi networks
• Fixes an issue where hands-free phone calls could become disconnected
• Fixes an issue where audio playback could stop working with some bluetooth speakers

Try using Google fiber IPV6 DNS... Ipv6 tunnels down and up... Or flow through on your wifi... If you dont have ipv6.. Dont worry.. It will use ipv4 close to use and then jump in ipv6 for request and retrieval of data then tunnel down to IPV4 as it comes back to you... This may not fix all your issues but may help the Page load faster as I have seen and other users have seen.... Try it...

type this in your DNS wifi... Google fiber ipv6... Works on all my Apple products...

Backup your iPad, erase and reinstall IOS, restore your stuff from the backup.

The pros advice.. Wow nobody would've thought of that what we do without you... Hahaha

I suppose it's more advanced thinking than a reset or taking to Apple store?

my problem is resolved with out doing a restore. I did further research and decided to try it. Did a reset of the network settings on the ipad, shut it down, rebooted my wifi router, restarted the ipad and then reconnected it to the wifi network. Three days later and no more dropped wifi. It might help someone else with the same problem

Just goes to to show that sometimes the simple things are best to try first

Thanks for telling us.

Even I have Wiki Connectivity issues. Tried all channel settings, reset wifi settings, reset iPhone (thrice) but no luck.

I connected my laptop with LAN/Wifi (it works always) and setup a hotspot (https://www.youtube.com/watch?v=zFHIvCMTqbQ) in Windows 7. Then connected iPhone 6 with hotspot. It is working perfectly. I can receive the same speed (2.5MBps) in the iPhone. If I don't use the phone for 2 hours and then I have to disconnect my wifi connection in iPhone and connect again and it works otherwise wifi is not working in iPhone again.

Hope Apple fix the issue in the next release. 😟

Hi All,

I had the wifi grayed out problem on my iphone and i was awaiting on every IOS release hoping that it would fix the issue. I just want to inform you all that this wifi issue is caused by a hardware problem (the wifi chip becomes defective and gives this problem. Apple has to answer this for the quality of wifi chip).

I replaced the wifi chip in a local mobile repair shop and now the phone works perfectly alright. The cost for repair is 55$.

So please refrain from waiting for next IOS update to fix the issue. Please replace your wifi chip and start using your devices.

In my situation I only need to restart the phone to restore wi-fi, but sometimes it may take a couple of attempts ( I used to frequently get the wi-fi enable button greyed out at the first restart, but this hasn't happened since 8.4) and this "fix" may last all day. It does seem however that the symptoms are not consistent across thone device with issues, so this may not work for you.

There is a very interesting article regarding Wi-Fi issues and Discoveryd reported on another Apple thread. Re: ios 8.3 wifi problems with wifi??

The post by David Shanahan, May 8, 2015, Page 7, provides the details and a link to the article. I hope iOS 9 provides some solutions to those affected.
