ios9 wifi not working

Hello,


Since updating to iOS 9 I cannot connect to my work wifi. It keeps telling me the password is incorrect even though it is identical to my PC which is connected. I have an iPhone 5s 16gb. wifi at home works fine.

iPhone 5s, iOS 9

Take a look at this Apple Support article:

I am working with iPads (Wi-Fi only) in a school district. After inadvertently allowing iOS 9 to update on one device, I found myself in the same boat as all of you. Followed elpcu's steps 2 and 3 directions. I could get connected to our wireless network, but could not get a web page to open. Message was "Safari cannot open the page because it could not establish a secure connection to the server." Saw this same message before and after doing steps 2 and 3. We also have an "outside" wireless connection with a home-use router (we use this to test VPN connections on our laptops). Had no trouble opening a webpage while connected to this Wi-Fi. Connected back to our district Wi-Fi network, and on a whim, I typed in the URL to the website for my personal email. This time I finally got our district login page, which then passes me through to the website.


Not sure others will find this helpful, but wanted to share it anyway. I know how frustrating this is for all of us. I could not see a way to downgrade to 8.4.x since I use Apple's Configurator to manage all of our iPads; we do not use iTunes.

My wifi on the ipad doesnt work, but my iphone and laptop works fine. I upgraded iphone from 8.x.x to 9.0 to 9.0.1 and everything works normal during the whole period. But I only upgraded my ipad from 8.x.x to 9.0 then suddenly the wifi doesnt work in the ipad. It worked the first few days. It can connect to the router with the tick sign and all, but its not downloading anything from the internet.


I did the whole force restart, turn on turn off, reset network settings etc but none of them worked. Then i upgraded to 9.0.1 on the ipad but still doesnt work. it connects to the router but no internet. I read all the methods to solve this issue but still doesnt work. Some people have different solutions to their wifi issue.


Help!

I have 2 iPhone 5s. One is a backup without a SIM. I upgraded it first and used it around the house for a week. Having no issues I upgraded the other 5s which I normally use which does have a SIM. The second won't connect to one of the wireless routers at home. It will connect to 3 others I have. 5ghz or 2.4ghz appears irrelevant. Of course the one it won't connect to is my primary. The backup 5s device with cellular turned off has no issues. No other device of many has issues with this router.


It just "spins" when connecting to the particular router. If you give it a bad password it will recognize as bad. I applied all elcpu's steps except 4 (it doesn't get that far), 8 and 9. I am hesitant to do 8 and 9 because I don't want to make the situation worse.


Is there a way to see what is going on in the background with the "spinning"?

Having installed either IOS 9.01 or 9.02 and since then you have had problems with "Connectivity" & or "Performance" (LAG) here are a few things to try:


Connectivity

1. Hard reset of device - Unlock device and then press and hold both the BACK BUTTON & the ON/OFF SWITCH at the same time the device with power off, KEEP holding these buttons until the "Apple" logo appears, the device will now reset and start up. NO DATA should be lost.

2. Remove your WiFi connection, go to "Settings" then "Wi-Fi" press the ⱷ icon and select "Forget This Network" when prompted select "Forget" Restart the device as per option 1

3. Set your device to have a static IP Address, Subnet Mask, Router & DNS. Leave Search Domains EMPTY, re-start device as per option 1


Performance (LAG)

1. Re-starting the device as per option 1 above. This may have corrected the problem, test to verify

2. Have you backed up your device via iTunes recently? If not, OOOPS! If yes, then you can perform a restore to an early version of the iOS

3. Backup the device but ensure you change the path within iTunes as to where you back up.

  • Within iTunes select your device then under preferences, advanced option change the location where it backups up. (Write this location down, you will need it later)
  • Call the folder iOS9 as a reference point. Backup the device.
  • Within Windows Explorer, select your device and then open the internal storage via explorer, you will see folders open each in turn and copy ALL your pictures to your PC, e.g. C:\IOSPictures\ this will allow you to put them back on to the device once you have restored it to an older version. (Only the missing ones)
  • If you backed up your device prior to installing iOS9> then you can skip this and just restore it back using the latest backup you have. (remember, if you have taken pictures or made any changes since this backup they will be lost)
  • Change the backup location back to the original location and restore the device. Once rebooted check the iOSx version and then copy back any picture from your PC

  • PLEASE Remember to ALWAYS backup your device before updating the iOS, just in-case... Whilst I hope the above helps, I do not take any responsibility for any lost of data, functionality of your device or ANY problems you may have after you have applied any or all of the above suggestion.

    The above is supplied free of charge and as such are used at your on risk.
