Change the LAN TCP/IP Settings
The modem router is preconfigured to use private IP addresses on the LAN side and to act as
a DHCP server. The modem router’s default LAN IP configuration is as follows:
• LAN IP address. 192.168.0.1
• Subnet mask. 255.255.255.0
These addresses are part of the designated private address range for use in private networks
and are suitable for most applications. If your network requires a different IP addressing
scheme, you can change these settings.
You might want to change these settings if you need a specific IP subnet that one or more
devices on the network uses, or if competing subnets use the same IP scheme.
To change the LAN TCP/IP settings:
1. Launch an Internet browser from a computer or mobile device that is connected to the
network.
2. Type http://www.routerlogin.net or http://www.routerlogin.com.
A login window opens.
