Step 4.  “LAN Setup” is shown in the diagram.   Each setup item of the local area network is 
default setting, and is not necessary to make change to it for normal operation.  Please 
input the settings on your own if change is needed. 
DHCP Setup:   
- ”enable” indicates that the DHCP function of the GN-BR402W is initialized, 
and will automatically assign an  IP address to the computer that is connected to 
the LAN end of the GN-BR402W.   (Configure the  DHCP starting address and 
the DHCP allocation number on your own.)   
- “disable” indicates that all IP addresses of all the computers connected to the 
LAN end of the GN -BR402W LAN. (It is not necessary to configure the DHCP 
starting address and the DHCP allocation number.) 
DHCP Starting Address:: 
When the DHCP setting is “enable”, the GN-BR402W uses this address as the 
initial value to assign the IP to the PC connected to the LAN end. 
For example, the DHCP starting address is 192.168.1.1   
DHCP allocation number is 50. 
The IP allocable range of the DHCP is from 192.168.1.1  to  192.168.1.50.
