Flash the Extender Node
- Configure your wired internet settings to use Manual IPv4 settings with IP: 192.168.1.10, subnet: 255.255.255.0, gateway: 0.0.0.0
- Plug one Ethernet cable into your laptop on one end and into the "LAN" port of the power-over-ethernet power supply on the other end.
- Plug another Ethernet cable into your antenna on one end and into the "POE" port of the power-over-ethernet power supply on the other end.
- Push a pin into the reset hole and hold it.
- With the pin held down, plug in the power to the power-over-ethernet power supply.
- Watch the lights on the antenna - they will all flash together a few times, then they will flash up and down.
- Once the lights on the antenna are flashing up and down, you can let go of the pin.
You should be able to ping the extender at 192.168.1.20.
$ ping 192.168.1.20 PING 192.168.1.20 (192.168.1.20) 56(84) bytes of data. 64 bytes from 192.168.1.20: icmp_seq=1 ttl=64 time=1.54 ms 64 bytes from 192.168.1.20: icmp_seq=2 ttl=64 time=0.826 ms
In your Linux terminal, type:
git clone https://github.com/sudomesh/ubi-flasher cd ubi-flasher npm install ./flasher.js '<path to firmware>'
The terminal will tell you "The firmware has been successfully sent to the router. In a few seconds, the router should begin flashing its four status LEDs sweeping from left to right, then right to left (or up down, down up). This means that the router is flashing itself with the new firmware. Once the router goes back to having only the power LED lit, the router has been successfully flashed."
Wait until the antenna has only the power LED lit and you're done.
Firmware check failure
If you attempt to flash the extender and receive a 'Firmware check failed' error, then you have a version of the NSM5 that is protected from being flashed via the default TFTP method. You will need to obtain a serial to USB interface (USB to UART TTL Module Serial Converter, 5 pin) and use it to flash the firmware.

When connected to the NSM5 via a serial connection, a similar error is displayed when attempting to load the SudoWRT firmware image.

NSM5 Official Firmware
Official firmware from Ubiquity Nanostation M5 (NSM5)
USB to Serial Connection
The following notes describe steps to interface with a Nanostation M5 (NSM5) via the serial interface. This may be necessary to manually load firmware onto the device if the web interface or TFTP methods of flashing the firmware become unavailable due to manufacturers disabling these methods of firmware flashing.
Order a USB to Serial Converter
USB to serial converter devices exist at a cost of $4 - $8 online, with much lower pricing and longer delivery times if ordered from China. Search for "USB to UART TTL", including "5 pin" in the search. Make sure the specifications do not mention anything other than 3.3 volts.
Connecting to Serial
You will need to connect the following pins from the converter to the pins on the device.
- Ground (GND)
- Serial Out (Transmit / TX)
- Serial In (Receive / RX)
Begin by connecting the Ground of the converter to the Ground of the device. Next connect the Transmit/TX of the converter to the Receive/RX of the device, then connect the Receive/RX of the converter to the Transmit/TX of the device.
Serial Communications Program
You need to install a serial communication program. Linux users can use Minicom.
sudo apt-get install minicom
By default the Minicom program will attempt to use /dev/tty8, and will also attempt to initialize the device (expecting a modem) by default.
$ minicom minicom: cannot open /dev/tty8: Permission denied
Run the program so that it starts the program on the USB converter that is connected by adding `-D /dev/ttyUSB0`, and specify that it should skip initialization by adding `-o`.
You can also specify from the command line that it use the baud rate and '8N1' settings specified below by including `-b 115200 -8`.
sudo minicom -D /dev/ttyUSB0 -o -b 115200 -8
In Minicom, CTRL-A to get settings, then Press O, to access settings
Go to Serial Port Setup, use these settings:
- Set the serial device (should be /dev/tty/USB0)
- Baud Rate (Bits Per Second): 115200
- Settings '8N1' (short hand for 8 bits, no parity, 1 stop bit)
- Turn off hardware and software flow control
Reboot the device, and it will let you drop into a command line. You will then have to figure out how to enable the network from the boot loader (Uboot or Redboot) and transfer the firmware to the device to flash it.
The device will not detect the key you press unless Minicom is configured properly.
- To access the Help screen, Press CTRL-A, then press Z.
- To access the configuration/settings, press CTRL-A, then press O.
From the configuration window, select to view the 'Serial port setup'
$ sudo minicom -D /dev/ttyUSB0 -o -b 115200 -8 Welcome to minicom 2.7 OPTIONS: I18n Compiled on Jan 1 2014, 17:13:19.

By default the Hardware Flow Control will be enabled. Press 'F' to disable Hardware Flow Control. Press ENTER to exit the Serial port setup window, and then select EXIT to go back to the program.
At this point plug in the Ethernet cable to the 'Main' Ethernet port, with the other end connected to the 'POE' port on the Power Over Ethernet adapter that came with the device. As the device boots up, you'll see output similar to the following.
You'll need to make sure to press a key before it boots the default image.

This will cause the U-Boot bootloader to drop into a command line.
Although U-Boot can support two protocols for transfering files, kermit or y-modem, the bootloader does not support the loadb or loady. Minicom only supports y-modem protocol.
We do not have to resort to a direct serial file transfer however. The 'mtdparts' command that is used to define flash memory partitions can be used to reset the partition table to the defaults before running 'urescue' to start the TFTP server.

After it reboots if you see the first line mention 'sudowrt-builder', the device is booting the SudoWRT firmware build.
You can press ENTER once it is finished, and it should drop into the command line for the SudoWRT system.
