The AC68U router's leds turned on automatically

[johnnyboy]

After contineously running 18 days, the RT-AC68U's leds suddenly turned on today which I had manually turned off by press the button down at the back of it when rebooting.
Now I pressed again to pop up the button, nothing happened. Then pressed down again, the leds turned off.

The LEDs turn back on if you restart the wireless. Any changes you make to your wireless settings or enabling/disabling guest wireless will restart wireless without rebooting the router. Restarting other services may also turn the LEDs back on. I haven't looked into what other services do this.
