Another poster replied with how to switch to static addressing.  Note 
that to do that, you need to assign the static address OUTSIDE the 
range (scope) that your DHCP server (Linksys router) is offering to 
clients, or it will get stepped on.

The other way to accomplish what you want is to set up a DHCP lease 
reservation.  You configure the DHCP server to associate a specific MAC 
address with a specific IP address in the scope.  The server will then 
only assign that IP address to a DHCP request from the client with that 
specific MAC.

Either approach requires configuration of the DHCP server.  My Linksys 
router supports both settings.
