Router Support Detection. If your router model is not listed in the router database it is possible to find out if it would be possible to build DD-WRT support for the device. DD-WRT router support mainly depends on the chipsets (cpu, wireless NIC, ethernet chip etc.) used.
This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram. DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version (18.06 or later) onto it! See for details.1) This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation.This means that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless. See what you can do now.2) OpenWrt support for this device will end after 2019.19.07 will be the last official build for 4/32 devices. After 19.07, no further OpenWrt images will be built for 4/32 devices. See what you can do now. There are (at least) three revisions of this router: A1, B1 and B2.
Rev.A1 has been rebranded as. The FR-54RTR is a close enough match that it can be flashed with the A1's firmware from D-Link:There are DIR-600N and DIR-600NW, both have reduced hardware feature (although not reduced price). DIR-600NW for example have reduced to 8MB memory and 2MB flash. DIR-600NB is suspected to have reduced features too. Any 3rd party firmware are unlikely able to run on these reduced hardwares.
They seem only sold in China.Supported Versions. Serial header pinout: S JP3 pinout: h 1: VCC (3.3V) (square) o 1 i 2: RxS o 2 e 3: Txh o 3 l 4: GNDi o 4 de JP3 l d DS4LED2 DS5. This setup:works great for me. Just remember that you can't hook up a PC serial port directly.
You need a TTL to RS232 level converter. Note that the linked image above has the ports facing you, and LEDs facing away. This is opposed to the above images of the DIR-601 with ports facing away. Take note of the position of the square solder pad in relation to the others when soldering.You can also have a look at the picture in the USB mod section where these pins are labeled on the left-hand side.JTAG. Solder two wires onto pins 73 and 74 on the Atheros SOC. The pins can be counted starting from the upper left corner of the chip with the dot (pin 1) and counterclockwise along the sides. Beamng drive demo download.
Since the SOC has 128 pins, there are 32 pins per side. Pins 73 and 74 should be on the right side of the chip if you are facing the chip right side up. Alternatively, the two pins are 9 and 10 when counting from the bottom of the right side of the chip. The two pins should not have any PCB traces leading to them. Pin 73/9 is D- and pin 74/10 is D+.
I recommend using wire wrap to solder to the pins since it is very thin. Tin the wire wrap with a minimal amount of solder, hold it on top of a pin with tweezers and apply heat to a part of the wire not touching the pin itself with a solder-free tip. Do not touch the tip of the soldering iron directly to the pins like I did. You will likely bridge some pins, rendering the device useless unless cleaned (very hard to do, but possible and very time consuming).

The London edition is the “true” first and worth around $1,400. The New York edition is the “first American edition” and worth $250. Location is very important. July 26, 2010 by Irene Meyer-Lopez Every business is different—depending on your industry, size, and other factors—but when it comes to paying taxes, most small- to medium-sized businesses have a lot in common.
Use ample flux. Once both wires have been soldered, apply hot glue to the board and wires (not the chip!) to ensure they don't break off. If you don't glue them down, they will break off and will likely short out other pins.Once you have soldered the two wires on and checked your work, use a 15K Ohm resistor to pull the lines low.
(In my picture, I use 10K Ohm and 5.1K Ohm resistors = 15.1K Ohm since that is what I had on-hand.) To clarify, pulling the D+ and D- lines low means that you need to hook one end of the resistor to GND and the other end to one of the lines. Do this for each line. A 330 ohm resisror is not needed as specified in the USB host standard, so I suspect that the 330 ohm resistors are internal.Next connect the two lines to a female type A USB plug.
+5V (red) can be sourced from the router's 5V connector and GND (black) can be connected at any unoccupied GND pad on the board. D- is likely to be white and D+ green on the USB female plug. Alternatively, from the front of a female type A USB connector, pin 1 is VCC (+5V), pin 2 is D- (white, 73/9), pin 3 is D+ (green, 74/10), and pin 4 is GND (black). The ability to control LEDs has been confirmed to work on the DIR-601.

Once I get the WiFi LED working I will submit a patch to the developers for future OpenWrt images.
It seems as though the WiFi LED is not a standard GPIO pin. I am making this assumption for two reasons:1) I can't get the LED to turn on even when I define every single GPIO possibility.2) The LED does not turn on at router boot up like all the LEDs do.I don't think it is worth my time to get one LED to work, especially since there are now so many others working. My best guess is that the LED is actually tied to the wireless chipset and blinks whenever there is traffic.Also there is a empty spot on the PCB (DS2) where a LED could be present. It is likely this would be controlled via GPIO also, but the surrounding area is missing some passive components that may need to be put in.There is also a test point (TP29) near the CPU and a bit to the right of the serial header. This is likely a GPIO also. EDIT: TP29 = GPIO 11I will also host the modified mach-dir600-a1.c file for anyone that wants it (eventually).@jkiddo: - I recently ported the DIR-632-A1, and for this board the WLAN is not a normal GPIO, to get the WLAN LED to work you actually have to callap9xpcisetupwmacledpin(0, DIR632A1WLANGPIOLED);where DIR632A1 WLANGPIOLED is 0 in this case, I have seen it as 1 in other boards.
