since I had keyboard and monitor attached I could now try changing ccode setting from ALL to X2 as described in the linked thread. Unfortunately no impact whatsoever in my case - always limited to 2G4 channels 1-13. I am ready to give up here and continue using 2G4 for this device; it is my last 2G4 client and just one more nuisance

armbian-firmware-full has some additional files for brcmfmac43430* but not the afore mentioned brcmfmac43430-sdio.sinovoip,bpi-m2-plus.bin from the error message. Not sure if there was anything else in armbian-firmware-full to make a difference?

I did some fruitless experiments: apt install firmware-brcm80211 now we have file brcm/brcmfmac43430-sdio.sinovoip,bpi-m2-plus.bin (and others) but results in ieee80211 phy0: brcmf_fw_crashed: Firmware has halted or crashed to fix had to run apt-get reinstall armbian-firmware At least reverted successfully to previous semi-working state (2G4 connection working). Solution to get proper wifi 5G networking still missing

ok, I will leave it at that and prepare a backup plus another sd-card to boot from. Thanks

ok, thanks. Then I may eventually spend some time experimenting. If it works, I will report back. For now, other pressing issues have come up so I have to take chances (and move some of the more frequent changing application specific (log)files to one of the existing tmpfs portions and hope to reduce the risk of fs corruption beyond fsck automatic repairs) I must admit I am surprised this feature was not requested by most users of armbian - when choosing the sbc+armbian combination I had expected this was a typical scenario and would be covered; error on my side, live and learn, I guess

interesting. To make rootfs readonly was my futile idea to have armbian handle the regular hard power switchoffs with no clean unmounts&shutdowns gracefully. Do you have another suggestion for this recurring situation or do you think that any other means was neccessary at all? overlayroot was just something I found here from the past (but seemed to have stopped working out of the box for newer releases). I am very open to all suggestions. Thank you

I have the same issue running Armbian 23.02 Bullseye for an octoprint setup which regularly sees hard power switchoff - making rootfs readonly seems reasonable; is there any update/progress or failure, please?

https://paste.armbian.com/faquvejaxo works ok for my alternate 2G4 network. Scanning wifi does not show any 5G8 networks.
