WorldSpot firmware on Ubiquiti routers

Ubiquiti hardware have good quality radios and can be installed outdoor. They are safe to flash thanks to their integrated TFTP flash method.

WorldSpot firmware has been succesfully tested on the following Ubiquiti models:

NanoStation M2 loco (tested with the bullet-m image file). This model is a small low cost indoor/outdoor router with an 8Dbi 60 degrees directionnal antenna.
PicoStation M2 HP (tested with the bullet-m image file). High power indoor/outdoor router with a 6Dbi omni directionnal antenna.

It is very probable that worldspot firmware runs on all ubiquiti airmax M2 series:

NanoStation M2: High power version of NanoStation Loco M2 with 11Dbi 60 degrees directionnal antenna (2 ethernet: use ubnt-nano-m image file)
Rocket M2: High end router, compatible with very large antennas. (use rocket-m image file)
Bullet M2: other form factor product. (use bullet-m image file)

Note: The router mac address should be written inside the lower cover of the router. It is a 12 digit hexadecimal number which should start with 0027.

Worldspot firmware must be flashed with the TFTP method:

Download the correct WorldSpot firmware for your router
Power off the router
Press the reset button while powering on the router.
Leave the reset button pressed during 4 to 5 seconds until you see the red and yellow light flashing alternatively, meaning that you are in TFTP mode
Set your computer ip address to 192.168.1.X (X different from 20)
Plug your computer to the router
Launch the windows commandline (cmd.exe)
You should be able to ping the router at 192.168.1.20 (ping 192.168.1.20)
Change directory to the place you downloaded worldspot firmware (using command cd)
Then upload the firmware using the "tftp" command:
tftp -i 192.168.1.20 PUT openwrt-ar71xx-ubnt-bullet-m-squashfs-factory.bin

You can revert to ubiquiti firmware anytime using the exact same procedure.
