Here are some more logs from the AP that might shed some light. It

Do you really need TKIP to be enabled in the BSS? The easiest way of
getting rid of issues related to TKIP countermeasures is by disabling
TKIP.. If it is enabled, it will be used as the group cipher and as
such, even a single misbehaving STA would completely disable the BSS for
everyone due to the rules related to the countermeasures (must not allow
any use of TKIP, including the group cipher one, for 60 seconds).
The log shows one of the STAs reporting Michael MIC failures in
broadcast frames from the AP. Either that STA is misbehaving or there is
something wrong with the broadcast frames sent by the AP.
Since restarting (and rebooting) the AP didn't fix the problem, I am assuming
it is something in the station.
It would be nice for it to work properly, even if I have no special need for it.
Do you have any suggestions for figuring out what is wrong with the station?
What is the preferred configuration these days if we are not using TKIP?
Thanks,
Ben
