Byzantium: Wifi needs HKS toggle off/on to come up

Since one of the last system updates my Wifi does not come up alone. No Wifi and no Bluetooth symbols are shown in this situation, also not after entering the PIN. I have only the HKS for cam and micro in off position, the others in on.

After entering the SIM PIN this time I waited 5 minutes, then I toggled the HKS for Wifi/BT once. One minute later the L5 was connected to the AP. I have from this boot the dmesg and /var/log/syslog and will attach them also here.

The problem is not always reproducible.
