Hi, I use the latest Macbook Pro 15 retina and whenever I leave my MBP unattended for more than 15 minutes or so, when I get back, the wifi and everything is shut. Again I have to move my mouse and wifi gets connected. Why does that happen ? I have those 2 settings correct too ? http://d.pr/i/K5OA and http://d.pr/i/TENQ What am I missing ?
