My Lenovo IdeaPad laptop won't stay connected to the Wi-Fi?

All other electronics are connecting just fine (iPhone, other laptops, etc). The Lenovo will probably hold internet connection for maybe five minutes then disconnects and won't connect back. I've tried restarting it and switching to other Wi-Fi networks and nothing seems to be helping. It's a brand new laptop. Could I have selected a setting that could make it keep doing this? Any advice on how to fix it?

Added (2). My laptop shows all available networks, BUT once I click on the one I want, it'll say it's loading but then fail to connect.
