Since then, the missing tags in the tutorial have been added and it works! Mega-shouts to Iron for an extensive tutorial. All configurations can be done from the web interface. The modification will allow you to add non-volatile memory to bufflao router. I recommend using a SD card up to 1GB. Some forum users reported that they got 2GB working, but both my 2GB cards failed to work. The problem is that there are quite a number of bufgalo 2GB cards around.

It is only required for SD and mini-SD cards. So start with a SD card of 1GB or less to confirm that everything is working. There is another way to add storage capacity to your router, and that is by mounting a shared directory on your computer. Samba shares can also be made with Linux. Mounting a shared directory will make the available hard disk space accessible whr-g4s your router. You can read more about how to mount a directory with Samba here: The Samba tutorial is outdated.

Buffalo – DD-WRT Wiki

I will add a section to it to show you how to mount a Samba share with the V2. The modification is not difficult to implement, but some decent soldering skills are required and knowing how to operate a multi-meter would be very handy. Let’s have a look at the requirements to access an SD card via the simplest available protocol: In fact we do not actually need to actively whr-t54s the SD card via the Chip Whrr-g54s line. We can just always select it by grounding the signal.

So in that case we only need 2 outputs. Now let’s get to it and open our router to find what we need. Once you have opened the router you will have access to the PCB. To find these points we will need our general purpose friend, the multi-meter. It is very easy to find a grounded point, because ground is present all over the PCB. In most cases the input power ground will also be the ground for the whole PCB. So start looking at the input power connector.

This connector has quite big soldering pads, which makes it easy to add an extra wire. Once this point is found, verify it by checking big metal object on the PCB. Usually the metal housing around the transmitter see pictures below to find it will be grounded too.


To verify that the points are connected use the conductivity check of the multi-meter. Make sure the router is powered down. The connection between the points should give you a very low resistance, about buffaol same resistance as what you would get when just shorting the multi-meter probes. This gave me an easy ground access point, and is also a nice point for the routing of the wires. Once a grounded point is found we can start looking for the 3. Check your ahr-g54s supply specification that is written on it.

Check if it provides AC or DC at the output. Often AC is indicated with a wavy line: DC is indicated like this: Verify the information on the power supply with a multi-meter. If the power supply output is 3. To verify this you need to power up the router.

Be very careful with this, as it is very easy to short circuit the board with some parts lying around. Switch the multi-meter to DC volt measurement, range volt. The actual value that you find might be slightly higher or lower than 3. If you power supply states an output voltage higher than 3. You will need to find this power converter, and it’s 3. The power converter is a big component, usually close to the input power socket. Power up the router and connect one multimeter probe to a grounded point.

Then carefully use the other probe to check the voltage at big pads of the big components close to the power socket until you find the 3. It states that it delivers 3.

To control the SD card we need some outputs, which are connected to the inputs of the SD card. Routers usually contain LED’s to signal their status. This gives us a easy opportunity to find some output points. The only disadvantage bufaflo this is that we will lose the signalling functionality of the LED’s because they are now used for the SD card communication.

What we first should establish is which LED’s we can control by software. To do this login to the router and use the “gpio” command. So under Windows type in your bbuffalo box:. The default IP address is Telnet needs to be enabled for this, which it is by default. You can enable or disabled it in the services tab of the web interface. So watch the LED’s closely while giving the gpio buffzlo.

You can also use this little command line to make your life easier:.

It will switch on the LED for 3 seconds, then switch if off whrg-54s 3 seconds, and so on. Replace the “1” in two places to change it for other IO pin numbers. In the screen capture below you can see how it should look. There is one important thing to consider! The IO pins can be used for input and for output purposes, and as you might know, there is usually a reset switch on a router. So what would happen if you write the status of the pin that is used to see if the reset button was pressed!?


How to hard reset Buffalo AirStation WHR-G54S

Right, you create a reset. You lose your settings as if you pressed the reset button. You will lose the telnet connection and see the LED’s flashing. When the router restarts it can happen that the reset button is still “pressed”, which will cause the router to reset the NVRAM to factory default values.

It should be clear that you cannot use this IO pin for the SD card interface. In many cases you will not see a LED changing. This means that the IO is not in use, or perhaps is used for input purposes. The power LED is not software controllable in my routers. We need 2 or 3 outputs and we 5 found, so let’s make some choices. So now we have found some LED’s that we can control by software.

Each LED has 2 connections, a positive site anode and a negative site cathode. So an important question arises. Which side of the LED do we need to connect to? To answer this we need to use the multi-meter again. Send the command described above to make the LED that needs to be analyzed flash on-off-on. Ground one probe and measure the voltage on each side of the LED. We need to use the side of the LED that that changes between about 0.

The wrong side will be at about 2 volts when the LED is on, and 3. We need to find 1 input. The switches on the router are the candidates for this. This command will wait until a change in the switch position is detected and signal this by printing “00” or “01”. So execute the command and press all except reset switches and check if you see some output on the screen.

I already knew that the reset switch was behind GPIO 4. With the DD-WRT firmware it not used anyway; the router mode is defined by the software settings, not by the switch.

The switch has several leads going into the PCB. To find this pad we need a multi-meter again. We need to find the soldering pad that is at about 3. See the pictures below to see which solder pad I found. It is very important to leave the switch in the position where the multi-meter reads 3.

Leave the switch in the “Auto” position. If you don’t use it then just ground SD pin 1.
