ios9 wifi not working

Im running into a similar failure "Unable to find .." , Do you have Hidden Network settings in your Meru Controller

Thank you for replying. I've tried most of the items in your list, apart from a restore and going to Apple. Will consider a restore if nothing else helps.

Attention - Solution found to apple devices upgraded to ios 9 with problems of not finding wifi networks! Just use hotspot/tethering of any device to connect to internet and wake your device up and it will find all available wifi networks.

!!!PROBLEM SOLVED!!!

i'm using vpn – should told you guys probably before. i deleted the profiles and everything was fine again. 3G is working again, WIFI is working again. hope that this is kinda useful for someone.

i have iphone 6 plus and ipad mini 3, after i have tried using VPN service, the wifi and 4g stopped working, at the beginning i thought that there was a problem in my router setting, eventually, i discovered that after deleting VPN every thing return to function.

Didn't work for my mum.

Forget your Wi-Fi networks and reconnect to them. To get that done, go into your Settings > Wi-Fi > Select your connection > Tap Forget this Network at the top of the screen.

If those fixes don’t work, take a close look at your router. recommend you unplugging it for a good minute or so then plugging it back in. If that doesn’t help, see if there is a firmware update for your router. Each router is different so you’ll need to consult your manual on how to do this. If it is still do not working, taking the device to an Apple Store to get looked at.

Please see some of the posts that followed your own, some solutions have been found and they have kindly been shared by others, perhaps they will help you as well.... Good luck.

Not everyone in this thread is experiencing the same type of problem. For me, I do not believe there is anything wrong with my router -- since it worked perfectly minutes before I upgraded to iOS 9 on 2 devices -- and depending on what I do, I can connect to wifi.

1. If the SSID is hidden, my iPhone and iPad cannot find it. It is not a question of me not knowing how to set it up -- and I have done everything and every reset option short of a complete wipe-out of my device and full reinstall.

2. If the SSID is visible, my iPhone and iPad have no problem. As soon as I hide it again, my connection immediately drops.

3. If I tether my iPad to my iPhone (on cellular) and add the hidden network, the iPad finds it and switches to wifi. If it restart the iPad, the network is lost again and I cannot add it back.

Whether hiding an SSID is useless or not, Apple clearly supports it otherwise the "Other" option wouldn't be there. There definitely is a problem with iOS 9 -- perhaps with certain models of iPad or iPhone and perhaps with certain routers.

5Ghz WIFI do not work after IOS 9 Upgrade!

iPhone 6+, Guest WIFI in our company are using the 5GHz band and i'm unable to connect to it after the upgrade!

iPhone seems also to have issues to identify and display those SSID's on the 5Ghz band, serious problems.....

Worked perfect before the upgrade.

(MERU WIFI soultion in place and login via captive portal page, unable to connect and do ont either get any browser window to login any longer)

Don't work, no changes to the current infrastructure done, this is an serious IOS 9 bug! for us it seems to be related to the 5GHz band!

Similar problem with the college Wifi (Eduruam).

Since the update last wednesday, wifi is not working.

At home it works, but the eduruam doesn't.

This is also happening with el capitan.

Same problem. I called apple support yesterday and they tried to blame it on our networks at work. Then tried to blame it on my phone. I have no trouble connecting anywhere I've tried except for an of our networks at work, and I've tried everything suggested except reboot the modems because I don't have access to them.

So far the most plausible explanation I've heard is the new requirement to support only TLSv1.2 for 802.1x authentication. And, it only seems to be affecting devices capable of ApplePay. Due to the PCI 3.0 security, this makes the most sense. If this turns out to be the root cause, Apple could have probably done a better job at communicating the potential outage.

If you can no longer connect after IOS9, check that your wireless authentication can support TLSv1.2.
