My policy would be that if re-starting wpa_supplicant does not fix an
issue, it is most likely something in the kernel. If reloading the
driver does not allow the connection to recover, something seems to be
wrong in the driver/firmware. As such, I would suggest reporting this to
Intel driver maintainers as the first step.
