wifi password incorrect after iOS 8 update

I got this problem on my iPhone 5 after updating to 8.1.2

I randomly lost access to my wifi on my iphone and no amount of password entry would solve it. Tried resetting network settings etc. I use a BT hub3, by the way and that has always been rock solid.

All my other devices, ipad, appletv, macbook etc were fine. I figured I would try changing the WPA key on the hub, and lo and behold it worked (i changed the last character from a 6 to a 7) obviously, I then lost access from my macbook so I re-joined the network on that, and set the password back on the router to the one ending in 6.

My ipad then was able to work as before and I was able to join the iphone5 to the network once more. Very odd.

The only thing I can think is that Apple have introduced a new feature to change the mac address on the wifi to prevent snooping...

I wonder if this feature has caused a temporary glitch on my hub as it got introduced? I am sure my wifi mac address is now different to what it was in the past, looking at the hub records. Perhaps my hub thought another device was trying to spoof my iphone, and stopped it connecting, Who knows, but yes - changing the wifi password and changing it back certainly helped me.

Worked with Apple support. The steps below worked:

Closed all apps, shut down phone, unplugged base station, plugged base station back in, wait for green light, fired up phone and jjoined network. Tested with cellular data off

I had the same issue. What worked for me was;

change the the password of the wireless router--->attempt to connect iphone via new password (this should connect)--->change router password back to original--->reconnect iphone to router via original password

Issue resurfaced next day. Worked with support, reset all settings not just network. So far so good, but as suggested above probably easier to just change wireless password, then change back

nothing seems to work for me. Since 8.1.2 even the free wi-fi connection stopped working :/ It finds the wi-fi, but it just does not connect. On secure wifi I get the error 'Incorrent passwrod' and on free I get 'Unable to join'. I even restored the ipad and set it up as a new ipad, but it still does not work ....This thing is just useless without internet :/ I shouldn't have updated to iOS 8.

tried it 😉

To fix the problem

go Settings>privacy>location services>system services and switch off Wi-Fi networking. restart your device and try again.

I tried resetting network settings, no luck (funny how apple is now like microsoft. Problem? Just return do a fresh install. We'd rather have you spend time reinstalling everything, getting your settings how you want them, etc, and do this every couple months, than just fix our own bug).

Finally changing the router wifi password to something new, connecting, then changing it back fixed the problem.

Once again, I am thoroughly disappointed with apple. This is clearly a common problem, and they won't even tell us "Yes, we acknowledge that it exists, we are working on it". They are just completely mute.

Have the same problem as well on ipad mini. Nothing works

Tried the following:

-reset network setting

-restore

-DFU restore

-changed router password

-removed password requirement on network

-changed password encryption method

-check MAC address table

-manual setup the connection

I can however connect in the mac-store to the free wifi network, but nowhere else (very inconvenient to get in-store support). My device is out of warranty by 14 days. This feels like a software "feature" to convince me to buy a new one. I believe apple needs to acknowledge the problem and create a fix.

I just got a brand new Ipad Air 2 running 8.1 and had this same wifi password problem. The only thing that fixed it for me was adding the MAC address of the iPad manually in my router. Thanks for suggesting this!

thanks... it really helped me...

Well, I am in the unfortunate ones who can access everywhere but at work. I can access fine with my Android tablet and windows laptop, but not my new iphone 6. And I've tried everything suggested that you can try from the Apple end of it. The fact that every other device works flawlessly but I can't use my applie products (Iphone 6 and ipad) is a huge disappointment. Especially when this seems to be a widespread problem that Apple appears to have ignored.

Had same problem. Somehow , not sure why, got connected again by using CAPITAL LETTERS when typing in password.

Good luck

Ok i have another solution which has worked for me when i was connecting and disconnecting every time i opened up an App. I think the problem is that the phone gets confused between 5ghz channel and 2.4 ghz channel on the wifi router. To solve this you need to go into your router setting and change the name of your 5ghz channel to something else.

So i now have 2 channels when i search for wifi.

My normal router name (bthomehumb- numbers)

my 5ghz channel names (5ghz channel)

Then once done connect your phone to the 2.4 ghz channel. I now have no problems with connecting to my home net.

I hope this helps some of you
