What is reason code 2?

[LakesideLion]

We're getting a lot of disconnections for reason code 2.   

What does "the previously used authentication by client is no longer valid" mean?

Reason code means Invalid authentication. What type of authentication are you using? Can you give us information about the configurations? Like, Maximum bitrate, authentication, etc.

The SSID was setup to do 802.1X with Radius.  Our radius is through Network Policy Server.  Not sure where to find the other info you mention.

Hi
We had the same issue and it was because we reused an old SSID. Disable the SSID with the problems and create a new one with the same config.

I have the same issue. We have 3 sites and only 1 site is experiencing this problem.

We have wpa/wpa2 authentication and all our AP’s are using the default “Basic Indoor Profile” the issue is affecting Android devices more than other OS.
