Upgrade Ubiquiti RouterStation OpenWRT firmware

This post is a shorter version of the one found in the openwrt mailing lists.

First steps:
1. Unplug your RouterStation (POE cable) and remove wlan cards
2. Set your computers IP to be in the same network as routerstation 192.168.1.* (Don't use the routerstation 192.168.1.20 IP)
3. Set your computer to ping the ip 192.168.1.20 continously (M$ Win cmd "ping -t 192.168.1.20") to see that the RS is there.
4. Press and hold the RS reset button. (RS powered off at this point)
5. Connect the POE cable.
6. Wait for the rf light to show up. Your RS is now in failsafe mode, waiting for tftp-connection.
7. Use tftpd32 or some other tftp software to upload the new firmware to your RS's IP (192.168.1.20). In this software, it's the tftp Client tab. Enter IP (192.168.1.20) and select the new firmware, and press put.
8. Wait, wait, wait.
9. Eventually it should reboot.

New firmwares can be found from Ubiquiti Forum for RouterStation. Beware, the UPGRADE version will overwrite Redboot bootloader also.


Ps. Having a serial adapter and a cable to monitor the RouterStation is a very good idea during this process.

My output from the RS serial console during the flashing process:

TFTPD: waiting for connection...
