Wireless client failing auth - forget/disconnect

[mrjelly]

Hello,

I have alerts on clients failing to authenticate with the wireless network through the Meraki APs. However I appear to have a client that is constantly failing authentication which is muddying the reporting.

If I choose to 'disconnect' the client does this mean they will need to re connect the wirelss and put in the correct password etc?

What about 'forget client'

thank you

I believe this will not work unless you have recently changed your password.

Are 802.11r and 802.11w enabled on the SSID by any chance? If so, have you tried disabling these features?

Thanks for getting back, they are both disabled.

I am trying to track down who it is but any advice in addition to that tactic will be great.

You can't proactively prevent a client from trying to authenticate, as far as I know.   Keep trying to find them and get them to fix their incorrect cached credentials.  Unless, by some coincidence the device is managed using Systems Manager and you didn't notice this before 😁

A really common case for this is when authenticating against AD, the user changes their password but doesn't change the password on their mobile.
