Installing a new Firmware Image

NOTE: The firmware image for the routerstation and the the one for the are NOT COMPATIBLE.

  1. Under the most recent Attitude Adjustment repository, under ar71xx, find the image named "openwrt-ar71xx-ubnt-rs-squashfs-factory.bin" or "openwrt-ar71xx-ubnt-rs-jffs2-factory.bin".
  2. Connect to the Routerstation's WAN port, the LAN ports will not work for loading the image.
  3. Boot the system in recovery mode by holding the reset switch until the RF LED lights up while powering on the device.
  4. Set your PC to a static address of
  5. Check connectivity by pinging to; there may be an issue with the automatic ethernet polarity negotiation not working properly; if that is the case try to connect through a reverse polarity cable.
  6. Upload the new firmware to the device through WAN port using TFTP on the default IP address,
    GNU/Linux: tftp -m binary -c put openwrt-ar71xx-ubnt-rs-squashfs-factory.bin
    Windows: tftp -i put openwrt-ar71xx-ubnt-rs-squashfs-factory.bin
  7. Connect to on the LAN port after router reboots.
    GNU/Linux: telnet

Upgrading OpenWrt

If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the mtd command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.

LuCI Web Upgrade Process
Terminal Upgrade Process
  • via tftp mode
  • put RouterStation into tftp mode by holding reset button when turning it on
  • tftp -m binary -c put openwrt-ar71xx-ubnt-rs-squashfs-factory.bin
  • run tftp command from same directory where you downloaded firmware
  • wait for 5 minutes and then you can reboot the router if it doesn't reboot automatically

Basic configuration

Specific configuration

  • Connect the router's WAN port directly to your PC.
  • Configure your PC with a static IP address between and E. g. (gateway and DNS is not required).
  • Plug the power on and wait for the RF LED to light up.
  • While the RF LED is on immediately press Reset button few times.
  • If done right the RF LED will quickly flash 3 times every second.
  • You should be able to telnet to the router at now (no username and password)
