Why does my Wi-Fi signal keep dropping out?
If your Mac or iOS device keeps losing its Wi-Fi connection, it could be because you’re too far away from your router. Try moving closer to the router’s location to see if that solves the problem. If it does, consider either relocating your router to a better place or extending your Wi-Fi network’s range using a network repeater, such as an AirPort Express. You should also make sure you have the latest version of iOS and OS X installed, as previous versions of both have been known to have Wi-Fi issues.
