You know what first alerted me to this? My dog, my precious sheppie. Normally I would turn off the laptop , still connected, and try to sleep at a decent time (11 pm). She would get unsettled, up and down, making a bed here and there on the floor, scratching at the floor. I could not figure it out, she didn't need to go out and pee, if anything, she is an old dog and sleeping is a favorite hobby at her age. I remembered the advice to not sleep with the phone near your head, well, I dont have one, so I not only unplugged the lap top, I started to disconnect, and she was fine, settled. The router is in my sons room, I should tell him to try it, his room is at the other end of the house, I try to tell him that staying up till 3 gaming is the reason he cannot sleep, but, hey, I am his old mother and he knows so much more than I do (wink).
