D-Link DIR-300

<alertbox> WARNING: This document may contain errors which may result in damage to your router. USE AT YOUR OWN RISK. </alertbox> inlinetoc_2_4 Airlink101 AR430W

The D-link/Airlink is very similar to the La Fonera but only has 4MB of flash memory, it uses an atheros wireless device, and second you must access the RedBoot bootloader to install OpenWrt/Gargoyle. It is impossiable to install Gargoyle on a factory default DIR-300, so be warned that it is not as straightforward as with the other routers.

It appears that Dlink in there wisdom have changed the chipset of the DIR-300.

This procedure only works for revision A

This procedure has been tested and works with

P/N: IIR300NTO....A1G
H/W: A1 F/W: v1.01-tomi-1.0
S/N: P1RK 1850 XXXXX

WARNING: Bricking you router is a high if you get this procedure wrong. A serial cable should bring it back to life but this is quite involved and requires soldering a header on your circuit board

Install Procedure

We need to install a new redboot to do this we need to go to dd-wrt and lookup D-Link DIR-300 and install the supplied redboot

Assuming you want to install Gargoyle 1.0.14, then you need to copy the following files to your local TFTP server (for windows use tftp32

  • ap61.ram – Downloaded from the DD-WRT site.
  • ap61.rom – Downloaded from the DD-WRT site.
  • gargoyle_1.0.14-atheros-root.squashfs
  • gargoyle_1.0.14-atheros-vmlinux.lzma

Start the TFTP server and replace the bootloader as described here:

Install Method

Configure your local ip to connect your lan cable to the WAN port of the router. unplug the power cord and replug it. Now enter the redboot using telnet and ip and port 9000. connect your lan cable to the dir300 wan port. you might need several tries since its only available for 1 second after aprox. 5 sec. of booting (in the appendix is a windows instruction for easy connecting to redboot)

DIR-300 Info:
IP:, Gateway:
Default server:

Now start a local tftp server on your computer and place ap61.ram as well as ap61.rom in the root dir of this server

back to the redboot enter:

load ap61.ram

Now a new temporarily bootloader should start. (on serial console it will display some warnings. but you don't need to worry about this) Plug you lan cable to the lan port of the dir-300. reconfigure your ip to and connect via telnet to and port 9000.

Important: while doing the following steps. never unplug the lan cable or the power supply

DD-WRT> reset

now the unit will reboot and the new bootloader will be executed and is waiting for your connection. this will take 30+ sec.

connect to the bootloader with telnet on port 9000 and ip

Install Gargoyle

If DD-WRT is all ready installed on your router start installing Gargoyle form this point.

  • DownloadFon Flash (special version required) and configure environment
  • Select correct Ethernet port
  • Load gargoyle files
    • gargoyle_x.x.xx-atheros-root.squashfs
    • gargoyle_x.x.xx-atheros-vmlinux.lzma
  • Plug ethernet cable between router and PC
  • Unplug power to router
  • With fon flash click “Flash router now!”
  • Plug in power to router
  • Wait 20 - 30 minutes for router to finish flashing

Router should automatically reboot and install procedure is finished


Windows easy connecting to redboot

Appendix: download putty.exe to c:\ create a file an c:\ called redboot.bat with the following content:

rem echo off
rem ------------------------------------------------
ping -n 1 -w 1 > NULL
IF ERRORLEVEL 1 goto start
rem putty
rem ------------------------------------------------
putty.exe telnet:// -m redboot.txt

create a file on c:\ called redboot.txt with the following content:


start the bat file and power on the router… comes redboot
