Much better jfe. But one more point to be cautious on. DHCP acts upon broadcast requests. When your PC boots up with DHCP enabled, it send out broadcasts that any DHCP server will respond to. Broadcasts as the word implies go everywhere in a network except through a router (unless the router is specifically configured to help it through). So when you turn on DHCP, you can sometimes accidently screw up a network in that other PC's or PDA's will get their address from your server rather than another more appropriate server.

However if the wireless access point has a built in router function enabled and DHCP function, you shouldn't have to worry.
