Once I updated the Nano Station M2 with firmware 5.5.6 to 5.6.5.
Version 5.6.5 did not immediately become, as there was not enough memory in the device for downloading it, so I first had to upgrade to 5.6.2, and then 5.6.5.
I will describe the update procedure:
1) Download the new firmware from the official site
or for NanoStation Loco M2 here
2) Open the device web interface by typing its IP address in the browser (standard 192.168.1.20, standard ubnt login, password also ubnt).
3) In the web-based interface on the left, click “System”, opposite “Upload Firmware:” click “BROWSE” and select the previously downloaded firmware file, a window will appear in which click “Upload”, in the next message click “Upgrade” and wait for the upgrade to complete. Power at the time of the update can not be turned off, otherwise the firmware may be damaged and it will have to be restored.
How to recover I wrote in this article – Ubiquiti (UBNT) device recovery

This completes the update procedure.
After the firmware settings are not reset.
