I have iwm(4) in my laptop
When it is used with Android smartphone's tethering Wi-Fi access point,
Wi-Fi WPA2-PSK (AES) connection is disconnected with
iwm0: fatal firmware error
error message from kernel.
And only reboot helps me.
Standard Wi-Fi access point does not cause this error.
I have run(4) device and it is alway sane.

Do you have additional message from your device?

And TKIP connection is not stable (or not supported) for my devices.
I decided to use AES always.
