The Buffalo AirStation Wireless-G (WHR-G54S) router is easy to take apart, once you know how it is put together. The first time I took it apart, it took me a while to figure out what to do, so here's a little tutorial on how to take it apart quickly and without damaging anything.

Warning: Even if you don't break anything, this will still probably void your warranty.

Step 1: Find the screw and remove.

Remove power and network cables. It should be easy to remove the top gray plastic panel by simply sliding it away from the front of the unit. From what I've read, some folks have found the screw underneath this top panel.

I had no such luck, instead my screw was hidden underneath the "IP Address (Bridge)" sticker on the bottom of the unit. I had to punch a little hole through the sticker to gain access to the screw hole.

Once you find the screw hole on your unit, remove the screw. Mine required the use of a Torx T8 security screw driver to remove.

Step 2: Remove black face panel.

On the bottom edge of the device, you will find two square holes towards the front of the unit. Some units may have a sticker covering up these access holes. I was lucky, my unit didn't have any such sticker down here.

Gently push down and forward through these holes with the tip of a pair of needle nozed pilers and the first half of the black front panel should pop right out as shown in the picture.

Once the first half is unlatched, the other side should be easy to unhook from the blue AOSS button.

Step 3: Remove antenna and blue AOSS panel.

Unscrew the antenna. The blue AOSS edge panel should now be free to slide backward towards the antenna connector one notch. After sliding it back, the blue panel is easily removed.

Step 4: Open unit.

At this point, assuming you removed the screw in step 1, the entire unit should open easily into two halves. Congratulations! After celebrating, I'd recommend taping the T8 security screw to the inside of the top half so you don't lose it. You may never use this screw again, but someday far in the future, someone with less hacking inclination may want to put the device back together again with the screw. It would be nice if it was still around by then.

In the picture, you can see I've soldered in four new wires for gaining access to the serial port signals. The 4 conductor connector then connects to my WHRSERIAL circuit board (not pictured) or future microcontroller projects.
