Problem to connect to WLAN after upgrade to iOS 11

unknown

We are running a ZD 1100 with 9.10.2 Build 29 firmware and 7762 and 7363 APs.
After upgrading iOS devices from 10.x to 11 these devices cannot connect to the WLAN.
We are using pre shared Keys and WPA2.
Even if we try to use the guest WLAN a connection ist not possible.
What can we do resolve this issue?

Similar config: ZD1100 on 9.10.2.29, R500 and 7363 APs.
No issues after iOS update to 11/11.0.1 on at least 30 ipads so far.

However we use MAC authentication only.
So seems likely that the issue is PSK/WPA2 based.

have you attempted trying to connect them to a new test WLAN?

I've tried now a new test WLAN but no success.

We have also issues with connecting wirelesse devices running IOS 11 to our ZD1200. The devices running IOS 10 still working.
The firmware version is 9.13.1.0 build 11 and we use R500 AP's.

If Guest WLAN is set to open authentication and connecting to that fails, is it even possible to recreate the successful authentication that Max is seeing using just MAC authentication?

What about when using WPA-mixed authentication or when changing AES/Auto (TKIP+AES), even try WEP to see if that fails also.

Maybe try authentication against a different manufacturers WiFi and if that succeeds I would give Ruckus support a call.

We did iOS 11 update today, also lost connection to ZD1200 and 7363 APs. Apple support knows this problem. Connection to an old Zyxel NBG5715 Dual Band Router works with iOS11. I hope, Apple and Ruckus will fix the problem soon.

Do you have an URL to a site where you got this information from?

I have updated the firmware last friday to 9.13.3.0 build 121 and it looks like the issues are gone. People with an IOS 11 device that could not connect before are not able to open the guestnetwork and enter their guess password.

Yes we had the same fault. With no encryption (we have a third party Captive portal to authenticate users) it still did the same.
In the end I set the Wireless as a Guest policy, and then it would connect and hold connection, but still no Internet or portal page. This was due to a rule on our Firewall not allowing traffic from one port to another. ZD 1100 with 9.10.2 Build 29 firmware and 7962 AP's. We tried Unifi as well and same result, until I added the Rule on the router. Check your firewall.

Thanks for reply, we got new ZoneFlex R310 AP's and installed new firmware 10.0.1.0.17 on ZD 1200. Now, we have perfect connection to iOS11. The last FW 9.12.0.0.336 for the old 7962 AP's did not work.
