Installing OpenWrt

Use build root (selecting the RT-N56U configs in make menuconfig) to build your image. Then unplug router power cord, keep reset button down, plug the power cord back and release the reset button. This will put your router into rescue mode (led blinks slowly) for flashing. Then flash the device with the (windows program that comes with the hardware). The original web gui will not let you install any image.
