This is an automated firmware flasher for Ubiquiti AirMax devices though it should be usable for flashing any router that needs a tftp client for flashing.


Install dependencies:

npm install


Ensure you're connected to your node via ethernet, and that you have an IP in the 192.168.1.x range (and not This script expects your node to have factory default settings, but should work for any reasonably sane settings assuming you supply username, password and ip if they have been altered.


Simple example, for a router with default ip, username and password:

./flasher.js myfirmware.bin

All supported command line options:

./flasher.js --ip --firmware myfirmware.bin --retry 5 --debug

The "--retry 5" argument causes the flasher to retry every five seconds no matter if flashing failed or succeeded.

Usage as library

var UbiFlasher = require('ubi-flasher');
var flasher = new Ubiflasher();
flasher.flash('firmware_file_path.bin', {
  // you can add more options here
  // the options are the same as for the command line
}, );

Setting up a flashing server

If you want a server with an ethernet plug that will flash any devices that get connected with your firmware of choice, then you can use the initscript:

sudo cp initscript /etc/init.d/ubiflasher

Edit the UBIFLASHERPATH and FIRMWARE variables in the script to suit your needs. Then do:

sudo chmod 755 /etc/init.d/ubiflasher
sudo update-rc.d ubiflasher defaults
sudo /etc/init.d/ubiflasher start

Now the flasher is running, will start automatically on boot, and will flash any connected routers.

Remember to set at least one interface on the server to have a static IP in the range 192.168.1.x and not

Overlapping subnets

If you for some reason must run the flasher on a computer that already has another network interface on a 192.168.1.x network, then you can use the following workaround:

Assuming you have an existing network interface eth0 on a 192.168.1.x network and you want to run ubi-flasher on eth1, then ensure that eth0 is not managed by any fancy automation (like network-manager or ifplugd) and run:

sudo ifconfig eth1 down
sudo ip addr add dev eth1
sudo ifconfig eth1 up
sudo ip route add dev eth1 metric 1
sudo ip route add dev eth1 metric 1

You probably want to add these commands to the "start()" function in the init script, so they are run on start-up, though take out the "sudo" part before you do.

You may also need to add the line "metric 10" to /etc/network/interfaces in the section for eth0 and run:

ifdown eth0 && ifup eth0

After setting this up, your server will no longer be able to access nor on the network connected to eth0, nor will computers on those IPs be able to communicate with your server.
