EXT: I love DFRobot's CM4 Router Board hardware. I can't find anything to complain about. The closest thing would be that the sysfs LED control at /sys/class/leds/PWR/trigger doesn't work. The PWR LED is always on. (Controlling ACT works perfectly well.) So you can see how insignificant it is. In other words, I love my router.
