WLC 9800 DOESN´T CONNECT WITH SOME ANDROID DEVICES

[igalang1093]

Hello,

I have a problem with some android devices, some of them can´t be connected to the wireless network through PSK, they only can connect to one of the SSID's which is using  Web authentication. I have a Catalyst 9800 WLC and 9115 AP.

I hope you can help me.

I can confirm that ap with image version 17.3.3.26 is affected.

We are facing the same issues.
WLC Version 17.3.4 on C9800-80 WLCs

We have Nokia 4.2 and OnePlus devices and also iPad Gen 7 with iOS15.x with those Problems. We will try to disable FT and AES Password Encryption today and test the devices again. I will update you with the results

According bug https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvu24770

your version was / is not within listed one.

What was the result ?

I do agree with Michael,

Recently I've experienced this issue on AP 9120 and WLC 9800. The issue was intermittent SSID connection. Hopefully it was due to the back dated android OS.

Fix: For me it was solved, "Fast Transition" should be selected as Enabled.

Configuration>Tags & Profiles>WLANs> Security

Hopefully it will work. If still persists, please post here.
