Trouble Staying on WIFI

[JohnDubya]

I have a user that is having problems with their WIFI and is spamming me with a lot of errors. The customer is having issues with connecting to guest WIFI and disconnecting shortly afterwards. I've tried to search these up but no information is present with some of these errors. Thanks!

What firmware is the controller running?

What is the wireless client (manufacturer)?

Is this affecting one wireless client or multiple?
