The problem I think it is that the manufacturer updated the hardware (it is now V1.2)
Here is the official answer;
our products and systems need to be updated, so every batch of hardware and software is updated. The products produced this year have updated DDR materials, so I think This is one reason. In addition, since armbian is not our official system, I have asked for technical help, and they have no way to solve this problem. We will remind on the official website that WiFi is unavailable.
