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 a web browser from a computer or mobile device that is connected to the
modem router network.
2. Enter http://routerlogin.net or http://192.168.0.1.
A login window opens.
3. Enter the user name and password.
The user name is admin. The default password is password. The user name and
password are case-sensitive.
The BASIC Home page displays.
4. Select ADVANCED > Setup > LAN Setup.
The LAN Setup page displays.
5. Clear the Use Router as DHCP Server check box.
6. Click the Apply button.
(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.

Manage LAN 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 accesses the modem router's DHCP server.
Assign reserved IP addresses to computers or servers that require permanent IP settings.

Reserve an IP Address

To reserve an IP address:

1. Launch a web browser from a computer or mobile device that is connected to the
modem router network.
