Pi5 network disconnects

[noiselevelzero]

I have been running Batty Birdnet off of a Pi5 for a few weeks now, and it certainly runs better than it did on a Pi4, except for one thing. For a reason I cannot diagnose, BBN will eventually drop off the network, and will not again be visible until I reboot the PI5. This almost always happen overnight, after the system becomes active collecting, and not during the day when it is not processing. As far as I know, this never happened on the Pi4, but this consistently happens on a PI5.

So far, I have tried multiple SD cards and even an NVME SSD, and have swapped Pi5's as well, none of which helped. I have also tried a number of "keep alive" Network Manager strings set up in various ways to autoexec and keep the WIFI connected, none of which worked.

To make a final check, I wiped the SD card and rebuilt it with just the OS, but did not then install Batty Birdnet from the script. I placed the card back in the pi, and reconnected my audiomoth so I could duplicate the same audio interface in case that was also an issue.

So far, the Pi5 has been stable for several days, leading me to believe this issue is with the Batty Birdnet build in some way. I could try to stress test the Pi (for instance with something like cpburn) but before I bother with that, does anyone else have an issue with their Pi5 using Batty Birdnet? I really would like to have this working on the Pi5 reliably.

Thanks.

It's a week now with no network disconnects of the Pi5. I will now reinstall Batty Birdnet from the script and advise the results.

Reinstalled from script, and the device has dropped off the network but not stopped observing as far as I can tell since the first night with BattyBirdnet loaded on the Pi5. The symptoms are the main web page and an SSH connection is unreachable from anywhere on the network until a hard restart.

It is possible this is something completely unique and common to two separate PI5's, two separate Audiomoth devices, 4 power supplies, 3 USB cables, 4 SD cards, and an NVME drive. However, I strongly suspect that this system is not Pi5 compatible. :) Lack of any replies makes me believe this is not an issue for others, or no one else is running on a Pi5.

Regards.

I don't know wether it has something to do with your problem and wether it helps somebody to find the cause. I have exactly the same problem on a different setting since a couple of days.
I had https://github.com/Nachtzuster/BirdNET-Pi running on a Raspberry 4 flawlessly since february. Now it disconnects from local Wifi-Network short time after reboot. The recording keeps running, but the webinterface is not reachable. Maybe it has something to do with an update on a source both projects still share?

Hi, I have the same issue with one of my setups on a Pi 4. It did not go away with a fresh install. Might be an issue of the current RaspberryPi OS.

After a recent update of RaspberryOS it works better on my system that was faulty. You can try

sudo apt-get update && sudo apt-get upgrade -y

in the shell (via ssh login or via UI in Tools - WebTerminal log in with the username (not birdnet) and passwort for the operating system that you defined when flashing the RaspberryOS.
Hope that works for you,

Thank you, I'll give that a try. I had been initiating a reboot every 4 hours to keep the system interface from becoming unavailable. I'd also replaced the regular SD Card with an industrial level card, from the perspective that maybe the number of writes was causing early card failure. Hopefully the latest version of the Raspberry Pi firmware does the trick.

FYI I am also testing these options here: https://support.thepihut.com/hc/en-us/articles/360014695877-Raspberry-Pi-won-t-connect-to-WiFi

• Localization settings
• power supply
  etc.

I found something in an IT journal that I am trying now to stabilize WIFI connection. It does appear to be a RaspberryOS issue: https://www.heise.de/ratgeber/Raspi-mit-Debian-verliert-Internet-Verbindung-9998575.html

It appears that a daemon is killing the wlan connection. It can be disabled by

sudo systemctl disable avahi-daemon.socket
sudo systemctl disable avahi-daemon

I am checking the long term effects still. Has been ok for a few hours now.

Thanks. I will try that. You also turn off Wifi power management (which is on by default) using instructions here:
