I have an issue with several android phones where I get the following error:
....@wlan2: disconnected, received deauth: class 3 frame received (7)
some of them connect immediately, some of them connect in 1/5 tries and some of them 1/10 tries with the above error.
The same AP (WAP AC v6.48.3) if I change the configuration to CAPsMAN it works immediately with the same clients. The moment their wifi is turned on they IMMEDIATELY connect fine.
If I change back to non-capsman mode the problem comes back.
I have reset the wifi interface and just added the SSID and the security profile which is wpa2-aes (like in the capsman mode) and the problem returns.
I change back to CAPsMAN mode and problem is solved.
Any ideas except moving to CAPsMAN mode?
