I'm having a very intermittent issue with the onboard wifi adapter crashing on my RPi4 after some time (days or hours) of being connected and online. The connection will appear up in LE settings however I can't ping the device at all. Enabling and disabling the wifi does nothing, only a reboot works.
I've had a look in the log and can't see anything related and am hesitant to turn on debug logging as this could happen hours or days after a boot and the log file would be huge. Here's a few things I've tried after getting onto it via a cable:
Is there anything else I can try looking at before I get a debug log?
