How do you set up a WiFi network (with more than one router)?

My family has AT&T and they set up our WiFi Router in the corner of the basement (which was pretty much the only place they could have set it up easily). The problem is our house is pretty big, so about 1/3 of the house has a mediocre WiFi signal and another third has no signal whatsoever. We have an old Apple AirPort from back before we had AT&T and an ethernet jack in the opposite corner of the house from the current router.
How do i set up the AirPort so it acts as a second antenna for the same network?

If both your routers has wifi technology, you can configure one as the main router and other a Access Point. The Access Point receive the wifi signal from the main router and transmit in that range. You can look in the below page for reference.
