Wireless client doesn't connect

[Ads321]

Hello all,

We have a user on the network that is unable to connect to WiFi.

When testing on external networks, it connects normally.

I checked the events and found the client fails many times during association, but then I have some events that he successfully connected for a few seconds.

Does someone has any suggestions to troubleshoot this issue related to error code 43?

Thank you in advance.

Do you have 802.11r and 802.11w enable? If yes try disabling it.

Yep, it looks like the device might be brain-dead and not support 802.11v.  You could try seeing if that device has any firmware updates first.
