iOS 8 Wi-Fi problems

Hi guys

Perhaps you should try these steps (it works for me so far, using iphone 5s & ios 8.0.2):

Turn on airplane mode

Turn on wifi only and join network

Test to see if the internet is running smoothly

Then turn off airplane mode to enable cellular again

good luck!

OK, now I really feel like an idiot. I'm posting this in case there are others like me who sort of know the basics, but get lost in conversation about DNS, packets, connection parameters, pings, etc. I knew enough to reset the router and did that when I lost the wireless connection after downloading iOS8. Tried some of the other things mentioned here too, like going to settings and tweaking this and that thing, but none of them worked. Yesterday my daughter noticed her Kindle wouldn't connect to the wireless network either. I did the usual -- went to settings, found the network, entered the password, etc. -- but the Kindle wouldn't connect either. Hmmmmm. Reset the router. Nothing. Decided to try resetting the modem and voila! In about 20 seconds, every device in my house found the network. Two iPhones, two iPads, one Kindle and a Surface tablet. Not suggesting that'll help anybody else, but I'm up and running as usual.

i had a similar situation. I'm almost certain that the root cause of the connection problems in my Wi-Fi network were caused by my iPad after I upgraded to iOS 8. No problems before the upgrade, unusable network after the upgrade. I had to reset the access point and modem to get any kind of speed to the network. I disabled Wi-Fi on the iPad and have had no problems with other devices since. The iPad loses 3G connectivity every couple hours (also a problem introduced by iOS 8), but that is a topic of another thread.

I'm somewhat frustrated by the posts' describing different workarounds involving routers, modems and other gear. First of all, based on my own experience, the fixes do not provide a lasting solution, and the symptoms are likely to return. If no one knows the root cause, these actions are just rain dances. The issues emanate from iOS 8 devices. That's the only logical conclusion I can arrive at with the evidence I have.

I'm starting to think that the problem is not iOS 8 itself but some changes on my router happend installing iOS 8 (is this possible????)

Let me explain better: I have a timecapsule 4th generation linked up to the router from my country adsl provider (the primary). I have now switched off TC and I'm now connecting straight to the primary one.

So far my iPad seems working at a faster speed and no wifi hangs at all. I'll keep you updated. If it works the problem will be to find the correct settings mysteriously changed by ios8....

I Had a similar problem with my iPad mini, not staying connected and resetting network settings only worked for about 5-10 minutes. Eventually I turned off the 5.0ghz broadcast from my router and am only using 2.4ghz. My iPad now stays connected.

Set my 5ghz to channel 161 as well and everything is great so far! Definitely not a fix but at least I can stream at home again. I have not tried YouTube yet but Dish and fox sports are working nicely. We will see how the next few hours progress.

I also had a problem on my iPhone 5 with safari not working (I use Chrome more so not as big of a problem) this was resolved by turning the iCloud sync off for safari.

What happens if you set 5Ghz to auto-channel? Suggestions in other threads indicate that may be the trick. Whatever channel the router picks, then manually lock it in.

It's a shame that "Bendgate" has taken the media spotlight because "Wifigate" is real and there may have been quicker action already. Interestingly, I found comments that this bug existed in the GM and betas.

I Have an iPad air that I upgraded to iOS 8.02 directly.

i Have had the same issues described here. Wifi connection just drops. I contacted Apple and they said to first try resetting all network settings and if that doesn't work try a Factory restore. I have done both. It might actually be worse after the factory restore.

I am quite confident there is not an issue with the router. I have an iPhone 5 that is still on iOS 7.1.2 and have been streaming audio on it all day. The iPad running iOS 8.02 has dropped the wifi connection 3 times.

apple suggested they may replace it but if the issue is occurring with new iPads and iPhones im not sure I am interested in that resolution.

I May have found a work around as my ipad had now been streaming non stop for about an hours no disconnections. try setting the access point to wireless 802.11b not N I know it slows down the speed and is not the best solution but it worked for me. If you have a duel channel access pong maybe set it so one of them is b just for the iPhone/iPad.

as I said not the best solution but if you are not transferring files via the wifi it is a good work around until Apple fixed the 802.11n issue.

An iPhone 6 is not the solution. I have two of them and both are experiencing the same wifi problems as discussed here. iOS 8.0.2 made no improvement. iPhones and iPads with iOS 8 suddenly loose wifi connectivity and show no network available, when I typically have 3-8 in range at any time. Only solution so far has been to restart device which then connects to network just fine after restart, for a while, then problem reappears. Certainly seems to be an iOS 8 issue. Other devices I'm running on iOS 7 have never shown this problem and devices now on iOS 8 did not show this problem until upgrading to iOS 8. I have 8 iOS devices and only those on iOS 8 are experiencing this problem. Kinda obvious where the issue is.

Seriously just turn off the dual frequency settings on your routers. Yes it's crap that for some reason apple can't fix it but that's all it is, the software gets confused receiving dual signals.

This his works for me, it's super fast and I'm un subscribing from this thread now as people seem to not be able to read a fix and action it, if you don't understand ask your service provider and they will do it for you.

Good luck and just spread the fix instead of having a moan, apple don't read this.....

I'm glad that you are not having issues - but hundreds of us are. I do have the latest version of firmware on my very popular Linksys WRT1900AC, and I continue to have wireless issues with all latest Apple os products: iOS 8.1 and Mac OS 10.10. Mac OS 10.9 and iOS 7.X work perfectly with my wireless router - no issues at all. Once the devices have been upgraded, wireless becomes completely unusable. This also happens to me on the access points *inside the apple store*. And yes, I have reset my network settings at Apple's suggestion repeatedly. This does not help situation. I have submitted multiple bug reports to Apple on these issues, and I am far from alone regarding these issues.

I have been monitoring this thread since my wifi issues started with the first iOS 8 update. Basically, Ive had no wifi or shoddy wifi or grayed out wifi and bluetooth since updating to 8.0 all the way through 8.1. Hours of my enjoyable life were burnt backing up, restoring, testing, and researching the issue.

Here is my resolution. I made an appt with an apple genius. Luckily, I was still under 1 year of purchase and was able to get my iphone 5s replaced immediately without any cost. His explanation was...sometimes a major release will exacerbate an already existing problem such as broken/worn down wifi/bluetooth chip.

Well that sounded great but I would have loved to be able to downgrade to iOS 7.xx to find out if that were true. Apple definitely rubbed me the wrong way with this experience. I will be selling my new 5s for a nexus 6 so i dont have to deal with iTunes and not being able to downgrade my iOS.

Good luck!

You'll find that if you do an over-the-air packet trace, that the phone itself is not listening to the network for periods of up to 400 milliseconds. Then all the packets come in a big burst, followed by another 400 millisecond silent period. It's quite strange, and I've been unable to find anything to 'turn off' or reset to make this problem go away.

I have, however, seen a device not have this problem. Powering off and on the phone makes the problem come back, however.
