Since I reconfigured my Chateau 12, I don't know why, every time I connect any Android or Ios device to the wifi, the internet connection is not available. However, if I connect a PC to the wifi, the internet miraculously returns. I enclose the configuration of the router, hoping you can help me solve this problem.
