Mobile Broadband 11n Wireless Router MBR1000
DHCP Settings
By default, the 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 router’s LAN. The assigned default gateway address is the LAN address of
the router. IP addresses is 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.
See the online document listed in "Internet Networking and TCP/IP Addressing: " in
Appendix B for an explanation of DHCP and information about how to assign IP addresses
for your network.
Use Router as DHCP Server
If another device on your network will be the DHCP server, or if you will manually configure
the network settings of all of your computers, clear the Use Router as DHCP Server check
box on the LAN IP Setup screen. Otherwise, leave it selected.
Specify the pool of IP addresses to be assigned by filling in the Starting IP Address and
Ending IP Address fields. These addresses should be part of the same IP address subnet
as the router’s LAN IP address. Using the default addressing scheme, you should define a
range between 192.168.0.2 and 192.168.0.254, although you might want to save part of the
range for devices with fixed addresses.
The router 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 is the router’s LAN IP address.
• Primary DNS server, if you entered a primary DNS address in the Basic Settings screen;
otherwise, the router’s LAN IP address.
• Secondary DNS server, if you entered a secondary DNS address in the Basic Settings
screen.
• WINS Server (Windows Internet Naming Service Server), determines the IP address
associated with a particular Windows computer. A WINS server records and reports a list
of names and IP address of Windows PCs on its local network. If you connect to a remote
network that contains a WINS server, enter the server’s IP address here. This allows your
PCs to browse the network using the Network Neighborhood feature of Windows.
Reserved IP Addresses
When you specify a reserved IP address for a computer on the LAN, that computer always
receives the same IP address each time it access the router’s DHCP server. Reserved IP
addresses should be assigned to servers that require permanent IP settings.
