Starting from the base that I do not modify the Router, nor use it only in the face of modifications, inexplicably or Poltergeist. The Lamp with its MAC address appeared on the Router, as Denial access, which I do not understand, since I did not select it that way, since the Router, barely or nothing, looked at it or configured it. Result, once the access, or MAC address of the lamp, is removed, it is back to life;).
Topic Solved to be taken into account, given that I do not touch or nothing the router or MAC addresses of the house, and this one appeared blocked without knowing the reason.
