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 you have competing subnets with the same IP scheme.
