  You will need a crossover cable to connect the two routers.

  To enable all of the ports on the new router to be used, you would connect
its "WAN" port to one of the "LAN" ports of the first router.  The problem
with doing that is that the second router will be trying to use the same
range of addresses on both its WAN and LAN sides, and that's a no-no.  SO
there is additional configuration needed to make this work.
  A simpler alternative is to plug the crossover into one of the LAN ports
of the new router, so its other LAN ports and wireless are "on the same side
of the router" as the LAN ports on the existing router -- don't use the new
router's WAN port at all.  All you have to do to make this work is turn off
DHCP on the new router, and assign the new router a new 192.168.1.x address
outside the range offered via DHCP from the first router.  (You may have to
increase or decrease the number of DHCP addresses offered by the first
router.)

  It depends which way you connect them; I recommend tha approach that
doesn't have this effect.
