Wlan stops working suddenly

  • Platform information: Rasp Pi 4 with 4GB Openhabian latest Version

My openhab system was working for more then a half year without any problems and yesterday wlan istn´t working anylonger. Problems with pasing IP it says in the openhab welcome screen after reboot. No change with plugged ethernet cable.

Is there a solution known? Yes I could start with a freshsystem and use a autobackup of the openhab, but anybody knows how to save my node-red configuration with all the flows I made?

In the moment the only way is to use a monitor and keyboard.

  • Is there a solution for the wlan problem or perhaps a known reason?

  • Where are (which folder) the flows located (should be one json file)

Thank you for help

did you also try if a reboot of your router solves the problem ?

Yes, I tried to start the router, but no change.

Can you maybe share some logging from your raspberry pi?
It looks like a problem with a static IP in the raspberry pi, did you set any that you know of?

Yes - the static IP is set in the fritzbox. After Ive deleted this in the fritzbox configuration, openhabian was able to connect via ethernet.

Now I could save my node red flows :slight_smile:

Do you know if its better to set static IP at router level or in Openhabian?

Good to hear that it is working now!
Probably a problem with handing out the static IP to the Raspberry Pi.

Do you know if its better to set static IP at router level or in Openhabian?

Personally I would say, set in in your router. then you have a central point for the administration of your IP addresses. If for some reason your network changes, you only have to change it in your router.

Have you ever come across this daring, revolutionary new concept of reading the docs ?

Hi Markus,

you know how it is - panic mode, because hole Smarthome is down and no nerves to read docs :sweat_smile:

But thanks for reminding and sending the link. I only know the old(er) docs and I´m flashed by the new ones.
