Hi anyone knows how to disable the DHCP service?? I've assigned IP numbers manually to all computers in my wireless and cable network including my DSL connection then I disabled the DHCP client service. My LAN still working properly but my DSL connection stop working unless I start the DHCP client service back. Can someone explain to me why?? How can I disable the DHCP service so that others who join my wireless network without my authority won't get any IP address?
