These firmware files are suitable to install the SECN firmware on Atheros
AR23XX based devices, like Ubiquiti NS2, D-Link DIR-300 (later generations
of the DIR-300 use Ralink chipsets, they are not supported) and others...

The idea is to make non-MPs usable in a SECN environment as range-extenders.

DISCLAIMER: Use at your own risk. Tested only on NS2. No guarantee, no 
responsibility, no flames, no complaints. No support for switch ports (they
will simply act as a hub, or might not work at all)

In order to flash Ubiquiti NS2s via telnet from the bootloader, use the .bin
image (contains kernel and rootfs).

Default IP address of the firmware is 103.130.1.20/24, fallback-IP is
172.31.255.254/30. The AP is WPA-PSK encrypted. Password: "potato-potato"

There are some caveats:

1/ There is no support for serial console. You will hardly need it.

2/ Firmware flashing from the web frontend or via the sysupgrade command is
not supported on non-MP devices.  Use the "mtd" tool to update the firmware. 
(i.e.  copy the *.lzma and .squashfs files into the device to /tmp via scp)

Then perform:

cd /tmp 
mtd write openwrt-atheros-vmlinuz***.lzma kernel
mtd write openwrt-atheros-root***.squashfs rootfs
reboot

Enjoy!
