The modem router delivers the following parameters to any LAN device that requests DHCP:

Disable the DHCP Server Feature in the
Modem Router
By default, the modem router acts as a DHCP server. The modem router assigns IP, DNS
server, and default gateway addresses to all computers 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.
To disable the DHCP server feature in the modem router:
1. Launch an Internet browser from a computer or wireless device that is connected to the
network.
2. Type http://www.routerlogin.net or http://www.routerlogin.com.
A login window opens.
3. Enter the user name and password.
The user name is admin. The user name and password are case-sensitive.
The BASIC Home page displays.
4. Select ADVANCED > Setup > LAN Setup.
5. Clear the Use Router as DHCP Server check box.
6. Click the Apply button.
7. (Optional) If this service is disabled and no other DHCP server is on your network, set your
computer IP addresses manually so that they can access the modem router.
