I have a rocket M2 XM on my tower. When I went to update the firmware, a line appeared that said:
hardware type ubnt (nanostation-m
This is clearly wrong, and the free memory of 46284KB confirms it is not a nanostation.
It would not accept a rocket update.
It did accept a nanostation update to 3.20.3.0, and it seems to work.
I tried other updates, including another to 3.20.3.0
They all fail and say:
Firmware cannot be updated
Upload file is not recognized
Failed to restart all services
Please reboot this node
