I have a Raspberry Pi 5b running the latest bookworm version from Raspberry Pi Imager v1.8.4: Pi OS (64-bit) with Raspberry Pi Desktop. I followed the different steps to install the OS with WiFi on a USB memory stick. I also did update the OS with apt update and apt full-upgrade.
Next I generated a virtual WLAN1 interface on WLAN0 and turned off power save in /etc/rc.local:
Next i nstalled an access point on WLAN1 with NetworkManger:All works fine for few hours or up to several day. Then suddenly the network indicator on the desktop is grayed out and states,
that wlan0 is no langer available. The WLAN router (FRITZBOX 7490) has a strong and stable WLAN signal and is located nearby the RPi 5b and is still connected to other devices in the WLAN network.
Also the access point is still reachable by using smart phones or tablet computers. The log generated by journalctl shows the following errors, when the wlan0 connection disappears:
This problem continues endlessly. It can only be fixed by restarting the NetworkManager Service.
If I set up the system with the 32Bit OS-Lite version of Bookworm in the same way and run it on a Pi zero 2W, there are no problems.
Does anyone have an idea of what might be causing this error?
