SETTING UP YOUR COMPUTERS
The Router has the ability to dynamically allocate network addresses to 
the computers on your network, using DHCP. However, your computers 
need to be configured correctly for this to take place. To change the 
configuration of your computers to allow this, follow the instructions in 
this chapter. If your computers are co nfigured with fixed or static 
addresses and you do not wish to  change this, then you should use the 
Discovery program on the Router CD-R OM to detect and configure your 
Router. Refer to  Appendix A
 for information on using the Discovery 
program.
