Connecting wireless router to main router

HI, I have two router the first one is "Linksys: BEFSR41" and Your
company's "Airlink101: AR315W", now what I am having trouble with or
working on is that the linksys is connected to the broadband modem, and
is doing the pppoe. I want to know how I should connect the airlink to
the linksys router. I know that I could just let the airlink do the
pppoe, but I can't the disadvantage is if I do this, the modem and
router is in the corner of a room and if that router sits there and not
the corner of the other side, it would not be able to have range and
reach the wireless computers. For the wireless computers, I was able
to connect to the airlink wirelessly and even with able connected to
it, but anything that connects to it, does not go out to the internet.
linksys lan ip is 192.168.1.1 and the airlink lan ip is: 192.168.1.8

Ex I need a connection like this: modem-------linksys--------airlink

and not like this: modem-------airlink------linksys
