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:

https://support.apple.com/en-us/HT204051

Reset your network settings.

Settings - General - Reset - Reset Network Settings

Reset your device. This won't delete your data stored on the phone.

Press and hold the Sleep/Wake button
Press and hold on the Home button
Keep holding both buttons until the display turns off and back on with Apple logo on it.

Alternatively, you may go to Settings - General - Reset - Reset All Settings

Did you do these:

6) Determine if other Wi-Fi devices on network are working well (other iOS devices, Macs, PCs).

7) Try device at another Network, i.e., neighbors’, public coffee house, etc.

8) Restore the Device (ask for additional for details if desired).

If so what was the outcome? Please don't just say they did not work. The more details the better. Did you do a complete #9? A backup and a Restore are two different things, not sure what you meant above.

Also iOS 9 is just out - a bug is certainly possible and if so hopefully corrected in a 9.0.1 update. I remember iOS 8.01 all too well....

For me 3G and WIFI is not working at all (iPhone 5 with iOS9). Sometimes i receive messages (e.g. Whatsapp) but i can only see them in preview. Connection to the internet is dead afterwards instantly. I tried everything which you said @elcpu but it didn't work out for me. Funny thing is that these problems started 5-6 hours after i installed the update. so it worked for a while.

Very strange Miguel. As you know 3G and Wi-Fi are not related at all, have to be two different issues. Maybe the phone went on the blink but I bet you did not try my last suggestion... 9) Go to an Apple Store for hardware evaluation.

Sep 17, 2015 6:12 PM in response to elcpu

true, i didn't go to an Apple Store yet. I still hope that 9.0.1 will be released soon.

Don't hold your breath, as this is not a common issue.

Sorry

I also have this iOS9 WiFi issue on my iPhone6 when I don't broadcast the SSID. My other iOS 8.4.1 devices work fine with the SSID broadcast off. I have done the iPhone reboot and network reset, router reboot, manual WiFi setup - nothing has worked. Currently stuck with leaving the SSID broadcast on.

What is wrong with leaving SSID on? If it is PW protected with a strong PW what difference does it make? Mine are on all the time - I actually have a choice of 4 (3 routers, one dual band).

elcpu, sorry, must be annoying to you to see plenty of people with the same problem.

I meant I did a complete reset, erasing all from the phone, but first did a backup,

then I restore the phone from this backup. I did that at least 5 times, and reseted network 50 times....

I'll keep trying your steps, and hopefully not have to reach number 9.

Now I'm doing another restore from a backup. could even connect to wifi now, and could change the DNS.

it appears ok... let's see if it remains stable, I'll let you know. thank you very much for now, you really did help a lot.

When whe are so desperate like I was, we make some mistakes, the secret is to take a deep breath and go for it.🙂

You are right on Giuliano..... just slow and easy, all issues are eventually resolved. Thanks for your nice comments, they are appreciated.. 🙂

Sep 17, 2015 6:44 PM in response to elcpu

Nothing is wrong with broadcasting your SSID. It was once thought by people ignorant about security that broadcasting a network name was somehow less secure. In fact, even the initial versions of the PCI-DSS required it. That was removed in 2.0

Folk's,

I'm seeing the exact same problem here that unless I turn on the 'SSID Broadcast = Yes' on my router, my iPhone 6 with iOS 9 will not join my Wi-Fi network. As soon as I turn on the SSID Broadcast, it connects instantly. I'm using WPA2 Personal on the router and have gone thru all the normal steps of doing a clean install of iOS9, resetting the network settings, manually trying to connect etc. and none worked so far. For, now I've downgraded back to 8.4.1 till someone figures it out. Now, one of the suggestions that was posted earlier was to try using Google's DNS instead. Has anyone (skymon2?) tried it with keeping their SSID as hidden and if so, share whether this worked for them or not?, Thanks

Better question is why can't we turn SSID broadcast off? It has been working fine for previous releases. Why the change? Must be a bug. Turning SSID off is just one item in a list for security. No need to get into a discussion about tools that can still see it.
