wifi password incorrect after iOS 8 update

Hey Carolyn you are a life saver !

I had tried everything to solve this problem but your reset idea worked ! Thank you from the bottom of my heart and my hair which I was about to pull out !!!

How is this not an issue that Apple is looking into? My iPhone 5 and iPhone 5s both worked perfectly with my wifi router before upgrading to iOS 8. Now, they cannot connect. The funny thing is, I have 4 routers in the house, the phones work fine with 3 of them but not 1. I have 2 routers of the same model (same firmware, identical settings except the wifi channel and the SSID name). One router works fine and another does not. I checked every setting on my firmware. I went as far as getting rid of the wifi security altogether (not even MAC address filtering), and my iPhones with iOS 8 will not connect. My 3 iPads, which I have not upgraded to iOS 8 work fine. My Apple TV, Macs, PCs, Android devices all work fine.

C'mon, Apple. Show us some love here.

This is the same problem everywhere. I have iphone5 and I have the same problem. It doesn't happen at home to me, but at work since I have updated to ios8. It's a shame for a cellphone in 2014 to have problem coonectin to wifi

I am so regretful about updating to ios8. And I would went back to ios7 if there had been a way !

Generally iphone hardware and software is worsening after Steve Jobs and I'm thinking about buying a Note4 !

IiPhone 5 upgraded to 8.0.2. After a while, it displays the infamous password incorrect message although it was working fine a few minutes before. issue observed on several wifi networks, on which all other equipment (PC and Mac) including an iPad mini upgraded to iOS 8.0.2 work flawlessly.

This cannot be a hardware issue, rather a software problem linked to the upgrade. Really frustrating. Was considering moving to an iPhone 6, but the lack of consideration by Apple to this kind of issues may make me turn over to other brands. Incidentally the battery drains at an unusual rate, 30% in 45 minutes:(

I appear to have found a solution to the issue in my Oct 3 post (new iPhone 6 shows incorrect password on home network with 1-year old Airport Extreme + Nextel modem that connect to all other Apple and Android products). Phone also connected fine with WPA2 network at office using older Apple routers. Upgrade from 8.0 to 8.0.2 did not solve the problem.

The solution that's worked so far (24 hours and counting, with one power-off period for phone) is:

• Open Airport Utility on an already-connected device and go to the Wireless menu.

• Change Wireless Security option to "None" and allow Airport Extreme to reset.

• Phone now connects with no problem.

• Return Wireless Security to WPA2 Personal with Airport Utility and re-enter password (I didn't change mine), then let Airport Extreme reset again.

• Attempt to connect with iPhone and enter password, which is finally accepted (I kept phone awake throughout this process by periodically touching the screen, but don't know if this matters).

• Other devices on network may also require reentering password.

I hope this suggestion, offered on 8/5/14 by EricD12345 in the thread New iPhone 5s - constant "Incorrect WiFi password" helps a few more of those dealing with this aggravation.

After the the second iOS8 update, my 4s will connect to every WiFi network except for the one at work. My other devices and my coworkers' iPhones will connect to the network, but not my 4s. I have tried resetting Network Settings, rebooting the router. Resetting Network Settings worked the first time for about 2 minutes, until I let my phone sleep. Then, when I turned it back on, WiFi had disconnected, never to connect again 😟

I attempted to eliminate the password requirement on the airport extreme network but no joy. After I got rid of the password requirement my iPhone was still unable to join the unsecured network. The phone is still on 8.0. Unfortunately I am unable to update the os because I cannot get the thing onto a wifi network and it won't let me update until it is on a wifi. What a waste of $. I was a long time apple fan and thought I would try to come back after using android. Guess that was a mistake.

I tried that, too, with no luck.

I have upgraded to iOS 8.1 last night, and I no longer get the "Invalid Password" error, but now I get the generic "Unable to Join the Network" error. Maybe after the next update, the error message will change again. Progress!

I have the same problem on my iPad mini. I just updated to iOS 8.1 and I experienced this problem both before and after updating. It seems like if you are persistent you will make it through after 10-15 or so tries. It is very frustrating.

I was able to get the phone on my network at my office. I updated to 8.1. Back at home however I am still unable to get on the network. I still get the incorrect password message. When I remove the network security I still cannot join the I get the "unable to join" message. Putting the security back in place the message again changes to "incorrect password". I think I will send the phone back. Now...to get another iPhone or android.

Let me share a work around that has worked for me So far.

I Had an issue with my MacBook retina since I bought it last year and was not able to connect to 5Ghz high channels. Specifically on the 40mhz band, if I changed it to 20mhz it was fine, but half the speed for moving large data files around on my network. So I went back to the low channels like 44 but these frequencies don't pentrate my walls nearly as well and I have a week signal in the yard. The high channels I can walk 5 houses down and still get great speed.

Well the mac is in getting the wifi card replaced after this still was not fixed with yosimite, so I went back to the high channels at home. It's funny how all apple stores run Cisco wifi on high channels but only in 20mhz band or maybe they would see this issue also instead to recommend I buy a apple wifi router.

So today I picked up the iPhone 6 and nothing but issues on 5ghz. Tested 2.4 and seems stable. So then I changled the channle back from 157 to 44 amd now I'm finally able to complete a backup to the cloud without the wifi dropping. My iPad 2 mini retina is fine and the iPhone 5s seems fine on the high channels.

so I'm starting to think this is something again with high channels and 40mhz bandwidth.

oh before anyone mentions it yes I did all the standard scripting trouble shooting, resets, clean restores and bla bla bla.

So my request to all having issues is.

1. What channel are you running? If above 100 have you tried the lower end of the spectrum? If not can you and report back if it also helped you?

2. If your bandwidth on the channle is set to auto, or 40mhz can you try setting it to 20MHz and see if that helps and report back?

TiP some routers are able to run wireless N on 2.4Ghz and still uses the auto or 40Mhz bandwidth option in the setting. If your having these issues on a 2.4Ghz router try changing the bandwidth setting to 20Mhz like I did with the 5Ghz router. It might help you also. If it works please report back and let people know.

Im just looking for a pattern and sharing what helped me, then asking you to try and see if it helps you.

i Know, I know. This is not a fix. It's a temporary work around and apple still needs to fix this wifi stuff with the 5ghz range. It's a shame that great hardware and design is not starting to get a bad reputation just because of the software issues and not testing properly before releasing it.

if your reading this apple, it the mix of stable software, with hardware, simplicity and design that sells your product and was the reason I moved over years ago for that stable BSD kernel.i support enough to tech issues 70 hours a week and didn't want to deal with it at home. I admire the movement to bring everything together across all your hardware to be the same simplicity and the free OS updates for the Mac the last couple of years. But truth be told even junk unstable software is not worth being free. Please fire the guy responsible for this testing before release, and yes I have an idea on who this guys is also. Can you say apple maps?

I had this issue and tried all these things, none of which helped. Ended up getting my iPhone 6 handset replaced which has fixed the problem. Apple said that there is a hardware issue they are tracking in some devices.

My iPhone 5S and iPad were fine, using same router and same software versions and even same user profile migrated from iPhone 5S to iPhone 6. Seems in my case it was a hardware issue. Just thought I'd share for anyone else looking for solutions.

I have just received my iPhone6, 64Gb, Gold, from EE in the UK and have exactly the same WiFi issues.

Incorrect password / Unable to connect (on routers with free WiFi - my local Costa!)

I have upgraded my iPad Retina and old iPhone 4S to IOS8.1 with no issues at all. I'm running a basic BT HomeHub 5 and have changed channels, addresses, passwords up and down from WPA2 to no protection and every setting in between. My iPhone 6 refuses to connect.

Its November, and Apple do not appear to be admitting any faults with the hardware of the iPhone 6, yet EE are replacing my handset to solve the issue!

I cannot explain why this works, but it did: I'm using Xfinity (Comcast) internet service and their combined modem/wired & wireless router for wifi and suddenly couldn't connect this morning. When all else failed, I logged in to the Xfinity hotspot using my Xfinity account info and then attempted again to reconnect to the home wifi and voila!..it works again!

If you are using an Apple Airport router, perhaps this will work if you have been using Access Control to limit who can get onto your network . . . it did for me. Go to Airport Utility, select "Network", click on the Airport device icon, click on "edit" at the bottom right of the resulting dialog box, then select "Network" from the menu at the top, uncheck "Enable Access Control, and click on "Update" to restart your router. Both recalcitrant iPhone 6 units in my household worked just fine once the router finished restarting. I have been told that access control can be defeated easily by crackers who know what they are doing, thus, assuming you have a strong and well-guarded network password, enabling access control does little to enhance the security of your network.
