Wireless-N 150 ADSL2+ Modem Router DGN1000 User Manual
Configuring DHCP
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. See the
online document that you can access from
Appendix
Bfor 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.
Otherwise, leave it selected.
Specify the pool of IP addresses to be assigned by setting the starting IP address and ending IP
address. 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 settings 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, short for 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.
