WIFI on RPi 3 stop working

  • Platform information:
    • Hardware: RPi 3 B Rev 1.2 / 32 GB SD card
    • OS: openHABian V1.4.1 ?
    • Java Runtime Environment: According to OS
    • openHAB version: openHAB 2.3.0 Build #1249
  • Issue of the topic:

Yesterday I installed an uppdate of my routers firmware and in connection with it it rebooted.
All my equipment with wifi in addition to RPi 3 with openHAB reconnected again.
I have used openHAB with wifi for several months without any problems.
The RPi connected to the network with ethernet cable.
Has reserved ip numbers for RPi in the router.

Actions that I’ve made:
Restart the RPi, get following message at reboot: 2018-04-05 12:26:38.739 [WARN ] [g.eclipse.smarthome.core.net.NetUtil] - Could not find broadcast address of primary IP,
using broadcast address null of first interface instead.
Updated Build #1248 to #1249.
Configured the wifi in openhabian-config again, restarted.
FInd a link in an another topic to raspberrypi.org with this command to find network “sudo iwlist wlan0 scan”, no network was find.
Nothing of this has solved the problem.

Anyone who can help me?
