84 * AP96 has 12 unlabeled leds in the front; these are numbered from 1 to 12
85 * below (from left to right on the board). Led 1 seems to be on whenever the
86 * board is powered. Led 11 shows LAN link activity actity. Led 3 is orange;
89 * In addition, there is one led next to a button on the right side for WPS.
