Android phone not picking up Wifi while laptop will

[AC Question]

How do I get my android phone to connect to a wifi that it doesn't pick up? My laptop and other people's phones pick it up! I am in Greece with a samsung galaxy note 4 and it's not picking it up while iPhones will

Welcome to Android Central! Does the wi-fi radio definitely turn on? Does it detect any networks at all?
