Ap-sta-possible-psk-mismatch

TP-Link Archer C7 V2. 25.12.

Following keeps on repeating in the logs on a 2.4 GHz network. I only see it for one Android device trying to connect. It connects and looses connection randomly.

What is a local deauth request? Is this related to Disassociate On Low Acknowledgement? The box is currently checked.

Is this fix still valid?

The only time I've seen that is because the PSK (wifi password) entered into the client was indeed incorrect.

WPA2-WPA3 (SAE) mixed mode does not work with some clients. Any modern smartphone supports WPA3 so set the encryption to SAE only.

Local Deauth means that the AP made the decision to detach from the client, in this case because PSK verification failed.

This is older android machine and It had successfully connected before the disconnection, so wrong password is highly unlikely. Still searching. Just upgraded to the current version. Let us see.
