Device Name
This is an abbreviated name of the wireless modem router. You see this name for the router
in Network Explorer on Windows systems.
Use Auto IP
Select this check box if you want the wireless modem router to set up the LAN IP addresses
automatically.
IP Address
The LAN IP address of the wireless modem router.
IP Subnet Mask
The LAN subnet mask of the wireless modem router. Combined with the IP address, the IP
subnet mask allows a device to know which other addresses are local to it, and which have to
be reached through a gateway or wireless modem router.
Use Router as DHCP Server
By default, the wireless modem router functions as a Dynamic Host Configuration Protocol
(DHCP) server, allowing it to assign IP, DNS server, and default gateway addresses to all
computers connected to the wireless modem router’s LAN. The assigned default gateway
address is the LAN address of the router. IP addresses are assigned to the attached PCs
from a pool of addresses specified in this screen. 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 router are satisfactory.
Reserved IP Addresses Setup
When you specify a reserved IP address for a computer on the LAN, that computer always
receives the same IP address each time it accesses the router’s DHCP server. Reserved IP
addresses should be assigned to servers that require permanent IP settings.
