If you are connected with a crossover-cable (or have a network card that
support crossover simulation), you have to only setup IP addresses of
the same local vlan. For example 192.168.0.1 for your desktop interface
and 192.168.0.2 for your laptop. You should be able to ping each other
without having a route.

What should be the purpose of this wireless router? To connect the
laptop using wifi to your desktop?
As Connie said, please provide us with the output of following commands:
# /sbin/route -va
# /sbin/ifconfig -a
#
And also, drawing a schema of your idea of the network would be useful.
If you're new to linux world, I recommend you good documentation at
http://tldp.org/ -- it helped me a lot when I've started with linux.
