Using the WGX102 as a DHCP server
By default, the WGX102 functions as a DHCP (Dynamic Host Configuration Protocol) server,
allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to
the range extender's LAN. The assigned default gateway address is the LAN address of the
WGX102. IP addresses are assigned to the attached computers from a pool of addresses specified
in this menu. Each pool address is tested before it is assigned to avoid duplicate addresses on the
LAN.
For most applications, the default DHCP and TCP/IP settings of the range extender are
satisfactory. See “IP Configuration by DHCP” on page B-10 for an explanation of DHCP and
information about how to assign IP addresses for your network.
If another device on your network is the DHCP server, or if you manually configure the network
settings of all of your computers, clear the ‘Use router as DHCP server’ check box. Otherwise,
leave it selected.
To specify the pool of IP addresses to be assigned, set the Starting IP Address and Ending IP
Address. These addresses should be part of the same IP address subnet as the range extender’s
LAN IP address. Using the default addressing scheme, you should define a range between
192.168.0.2 and 192.168.0.253, although you may want to save part of the range for devices with
fixed addresses.
The WGX102 delivers the following parameters to any LAN device that requests DHCP:
• An IP Address from the range you have defined
• Subnet Mask
• Gateway IP Address (the range extender’s LAN IP address)
• Primary DNS Server (if you entered a Primary DNS address in the Basic Settings menu;
otherwise, the range extender’s LAN IP address)
• Secondary DNS Server (if you entered a Secondary DNS address in the Basic Settings menu)
