Guest users at a hotel surfing just fine then they get kicked off. When it tries to reconnect they get password error. They have to "forget network" and re-add it. Then it works for a while again.
Maybe a rogue AP trying to steal data? Have you looked at air marshal for anything?
It doesn't show any rogue APs. That's all I looked at so far.
Next would be what type of authentication on that SSID and what type of client? Maybe something around MAC randomization and hotel splash page authentication, etc.
No splash page luckily.
type='WPA-PSK auth fail' associated='false' radio='1' vap='1' Standard WPA PSK
Every kind of device seems affected equally. Android, Apple, watches, phones ipads etc.
And this has started happening recently and used to be fine, I suppose? Have you tried just rebooting MR's? And how often or (or rarely) does this occur? If you can easily reproduce it and have restarted MR's I would demonstrate to Meraki support and let them help you.
There is one update available. It didn't seem to have related fixes. maybe worth a shot.
It started a couple of months ago. I'm thinking there is rogue dhcp or something. or some layer 2 issue.
Check that the client doesn't have an old password saved, that they selected the right SSID, that they were entering the password correctly, and that the password was configured as expected. If all the details provided are correct, the client can still fail during the packet exchange required for a successful authentication.
This what shows in the event logs.
