•Enable or Disable the Wireless Broadband Router's DHCP Server function.

•Set the range of IP Addresses allocated to PCs by the DHCP Server function.

You can assign Fixed IP Addresses to some devices while using DHCP, provided that the Fixed IP Addresses are NOT within the range used by the DHCP Server.

Using another DHCP Server

You can only use one (1) DHCP Server per LAN segment. If you wish to use another DHCP Server, rather than the Wireless Broadband Router's, the following procedure is required.

•Disable the DHCP Server feature in the Wireless Broadband Router. This setting is on the LAN screen.

•Configure the DHCP Server to provide the Wireless Broadband Router's IP Address as the Default Gateway.

To Configure your PCs to use DHCP

This is the default setting for TCP/IP for all non-Server versions of Windows.

See Chapter 4 - Client Configuration for the procedure to check these settings.
