AC1600 WiFi VDSL/ADSL Modem Router Model D6400
Disable the Built-In DHCP Server
By default, the modem router functions as a DHCP server. The modem router assigns IP,
DNS server, and default gateway addresses to all devices connected to the LAN. The
assigned default gateway address is the LAN address of the modem router.
You can use another device on your network as the DHCP server or specify the network
settings of all your computers.
Note: If you disable the DHCP server and no other DHCP server is available
on your network, you must set your computer IP addresses manually
so that they can access the modem router.
To disable the built-in DHCP server:
1. Launch a web browser from a computer or WiFi device that is connected to the network.
2. Type http://www.routerlogin.net.
A login window opens.
3. Enter the user name and password for the modem router.
The user name is admin. The default password is password. The user name and
password are case-sensitive.
4. Click the OK button.
The BASIC Home page displays.
5. Select ADVANCED > Setup > LAN Setup.
The LAN Setup page displays.
6. Clear the Use Router as DHCP Server check box.
7. Click the Apply button.
Your settings are saved.
Set Up and Manage Custom Static Routes
Static routes provide detailed routing information to your modem router. Typically, you do not
need to add static routes. You must configure static routes only for unusual cases such as
when you use multiple routers or multiple IP subnets on your network.
As an example of when a static route is needed, consider the following case:
•Your primary Internet access is through an ADSL modem to an ISP.
•You use an ISDN router on your home network for connecting to the company where you
are employed. This router’s address on your LAN is 192.168.0.100.
•Your company’s network address is 126.96.36.199.
