Q: Macbook Pro 2103 Keeps Dropping Wifi Everywhere

Hi! I have a 2013 Macbook Pro, OSX 10.9.4, that keeps dropping the wifi connection after minutes of nonuse.  If I don't use it for two minutes, it drops.  It does this no matter where I am, or whose wifi I am using.  I tried changing channels on my router (which is a Netgear, one year old) which did nothing--but, as I said, it does this everywhere.  Any ideas? Help!
