TFTP Firmware Installation


For Ubiquiti Devices

TFTP is trivial file transfer protocol.
When you successfully complete the installation, the login user is ”root” and the password is “hsmm”.


The Steps in Brief

  1. Download the AREDN “factory” file for your device.

  2. Prepare your computer for the firmware installation via TFTP to your device.

  3. Put the device into TFTP mode.

  4. Issue the commands on your computer to send the AREDN firmware to your device.

  5. Wait for your device to reboot.

  6. Login to your device with a web browser and complete the device setup.


Detailed Steps

 

For Ubiquiti Devices


Download the AREDN “factory” file for your device

Obtain the appropriate firmware from the AREDN Download page at https://www.arednmesh.org/content/current-software 


Prepare your computer for the firmware installation via TFTP to your device

  1. If you are using a Windows computer, enable the TFTP client [see example at https://www.trishtech.com/2014/10/enable-tftp-telnet-in-windows-10/]
    OR download and install a TFTP command line client [example at https://www.pcwdld.com/tftp-client-for-windows-7  

  2. Close your browser [Chrome, Firefox, Safari, Opera, Internet Explorer, etc.]

  3. Disconnect or disable the WiFi on your computer. You will only use the wired Ethernet adapter on your computer for this process.

  4. Configure your computer’s wired network adapter to a static IP address of 192.168.1.5 with a netmask of 255.255.255.0

  5. Connect a CAT5 Ethernet cable from your computer to the POE adapter for your device. Use the LAN side of the POE adapter.


Put the device into TFTP mode

  1. Power up the POE adapter by plugging it into an electrical socket.

  2. Press and hold the RESET button on the node/device (or on the POE adapter if you have one with a reset button on the bottom). A wooden toothpick is a good tool to press the RESET button.

  3. WHILE CONTINUING to HOLD the RESET in, connect a CAT5 Ethernet cable from your POE adapter [POE side] to your device.

  4. WHILE CONTINUING to HOLD the RESET in, wait approximately 30 to 45 seconds until you see the LEDs on the node alternating in a 1-3, 2-4, 1-3, 2-4 pattern.

  5. Release the RESET button. 


Issue the commands on your computer to send the AREDN firmware to your device

  1. Open a command prompt in Windows (Start-Run: cmd.exe) or a terminal window on other systems
  2. A Windows TFTP client example follows:
    1. type:   tftp 192.168.1.20    [If your device is an AIRROUTER use 192.168.1.1]
    2. type: bin                 (This puts the transfer in the required "binary" mode)
    3. type: trace on         (This is optional, but will show you that it is transferring bytes to the device)
    4. type: put <then the full path to where you downloaded the AREDN firmware>
      For instance:   put c:\temp\aredn-3.18.9.0-ubnt-nano-m-xw-factory.bin
    5. The TFTP client should indicate that data is being transferred and eventually completes successfully.


Wait for your device to reboot

Watch the LEDs on the node cycle for about 2-3 mins and the node will reboot. The reboot is completed when the LED 4 light (farthest on the right) is lit and is steady green.


Login to your device with a web browser and complete the device setup

  1. Configure your computer’s wired network adapter to use DHCP addressing.
  2. Open your browser
  3. Browse to:   http://localnode.local.mesh:8080
  4. Click SETUP on the web page
  5. Login with user = root and password=hsmm
  6. Change the node name to use your callsign and any other identifiers that will make this node name unique. Change the node’s password. Change the RF settings (channel, bandwidth, distance value) to appropriate values for your area.
  7. Click SAVE
  8. Reboot the node
  9. Done
