@north1 The current Rock 3C image is for the older board revisions with wifi 5 module. For board rev 1.4 with wifi 6 module, the driver is available as a dkms package from Radxa's github. The board uses SDIO for the module, therefore for the latest version firmware release as of writing:
 
wget -O aic8800-firmware.deb https://github.com/radxa-pkg/aic8800/releases/download/3.0%2Bgit20240116.ec460377-8/aic8800-firmware_3.0+git20240116.ec460377-8_arm64.deb wget -O aic8800-sdio-dkms.deb https://github.com/radxa-pkg/aic8800/releases/download/3.0%2Bgit20240116.ec460377-8/aic8800-sdio-dkms_3.0+git20240116.ec460377-8_all.deb sudo apt install linux-headers-current-rockchip64 sudo dpkg -i aic8800-firmware.deb sudo dpkg -i aic8800-sdio-dkms.deb  
and then reboot.

Thank you for your feedback, I think you are right in that my problem related to an issue with 24.8.4.
 
I could not boot from NVME when I used kernel 6.1.75 with 24.8.4 (ie the version of images published here https://www.armbian.com/radxa-rock-5c/)
 
I built a new image using 6.1.75 and 24.11.0 (subsequently upgraded to 24.11.1), this now boots fine from the NVME drive.
