Linking two routers for better wifi

Hey y'all!

Hope someone can help - I bought a small router a few years ago -Netgear N150. Then, with more computers and wifi gadgets (and lots of walls in the house) I got another Netgear -N600 dual -and a switch. The N600 is connected to the modem, two computers in close proximity to it, and then one of the ports has a cable running to a switch in the basement so that all the kids' gaming things can be connected down there. Then one of the switch's ports is wired to come back up to the family room, and the N150 is in there for the TV (gotta love Netflix!). The routers were originally set up on two different computers and each has their own password, so we show two separate Wifi locations. They both have their stronger/weaker points throughout the house because of walls and floors.

The problem now is the phones/tablets/laptops that wander throughout basement, first and second floor, in and out of rooms, with teenagers and husband, now complaining to me about losing signals.

Is there a way to link the two routers to make one Wifi "network" that will work everywhere? I read something about this here once maybe a year ago, but I can't find the post anymore.

Thanks for any help - and please remember I am not an IT tech!! :confused
