We are experiencing WiFi issues with some devices deployed at one of our customers.
When the devices are booted, everything is working fine for a couple of hours to a day or two, but then the device disconnects and won’t reconnect automatically.
Power cycling the device always makes the device reconnect, but only for the aforementioned time.
The situation is similar to what is described in:
but upgrading to the newest OS hasn’t fixed the problem, and if possible I would rather not manually restart the networking services entirely as proposed.
The same devices work fine, when they are brought to our test-environment with a different WiFi-network, so it seems that it is provoked by the client’s WiFi.
Also, the exact same hardware setup and Balena application is running for almost a year now at other client’s without problems.
Is there any obvious fix for this?
Also can we get some NetworkManager-logs from the devices, that are not deleted after power cycling, that might point us in the right direction?
The devices are encased and are not readily accessible for us, so attaching external screens etc. for debugging is not really an option.
Hardware:: Raspberry Pi 3 Model B
OS-version: balenaOS 2.29.2+rev2

Hope you are able to help!
