rio Posted May 14, 2023 Author Share Posted May 14, 2023 (edited) 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 Edited May 14, 2023 by rio 0 Quote Link to comment Share on other sites More sharing options...
SteeMan Posted May 14, 2023 Share Posted May 14, 2023 Have you tried with armbian-firmware-full? 0 Quote Link to comment Share on other sites More sharing options...
rio Posted May 14, 2023 Author Share Posted May 14, 2023 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? 0 Quote Link to comment Share on other sites More sharing options...
rio Posted May 14, 2023 Author Share Posted May 14, 2023 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 0 Quote Link to comment Share on other sites More sharing options...
