Thank Marks, for the help. I will complement the answer with an additional suggestion. Install the WiFi analyzer. It will not only help to fix the issue, but it could help to improve your own WiFi network. Particularly useful if you watch videos or use other type of stream services, like internet radio/music, youtube, movies, etc.

A sophistical rhetorician, inebriated with the exuberance of his own verbosity, and gifted with an egotistical imagination that can at all times command an interminable and inconsistent series of arguments to malign an opponent and to glorify himself.
