Iphone 5 not picking up wifi after ios 8 upgrade

You're right, it's an iOS 8 bug with certain iPhone models, but not with others. - But I can tell you, the hardware is not affected.

After noticing that my Wi-Fi could no longer pick up any signal, I downgraded my iPhone 5s (iPhone6,2 model, mid-2014) back to 7.1.2 where the Wi-Fi works as well as it always has.

I also upgraded an iPhone 4s to iOS 8 and the Wi-Fi worked fine!

I have done the upgrade+downgrade about 5 times, now, using different upgrade methods (over-the-air, automatic through itunes, manual restore with different IPSWs (including pre-release iOS Gold Master)).

In other words, (1) I am certain this is a software bug, (2) I'm going to stick to 7.1.2 on iPhone 5s for the time being.

If you're considering downgrading, now: It's easy to do, but it only makes sense if you have a backup of your phone (on computer or iCloud) from before the upgrade, as backups made running iOS 8 won't work on 7.1.2. Furthermore, if you have such a backup from, say, two days ago, your phone "won't remember" anything from these last two days; you'll effectively travel back in time.

So, either you stick with iOS 8 but without Wi-Fi until a fix is released or you downgrade and lose two days of memory.

PS: if you tag this reply as having "solved" your problem, maybe it will be seen by more people and hopefully this will get more traction. Frankly, I am surprised this hasn't caused an uproar. I'm wondering if all those affected have noticed that their Wi-Fi is MIA.

Alright. Please make sure to let me know what they say. I'm curious. we can't be the only ones facing this problem.

Also, if "iCloud Backup" was enabled, you may have a backup "online". - Look under "Settings>iCloud>Storage>Manage Storage" or under "Settings>iCloud>Backup"

If you don't have a backup online (and none on iTunes) then the only thing (I think) they can do at Apple for you is to downgrade it to 7.1.2 so you can use your Wi-Fi again, but, you'd lose every content and setting on your iPhone (-> Restore to factory settings).

(That you could do yourself by downloading and installing the 7.1.2 firmware - see/download through eg. theiphonewiki.com)

If you can bear using it without WiFi for a while, it may be best to wait for 8.0.1 to be released.

Since iOS 1, Apple has systematically released an .0.1 version within 3 to 6 weeks of the initial release.

PS: again, if you mark this post as "having helped you", I think we may reach more people facing the same issue. I'm still surprised to have found only two other people online who have the same problem.

Hi, my iPhone 5s will not connect to iTunes via wifi when I open iTunes.. WiFi as per iPhone is Ok..
