Configure the Modem Router as a DSL Modem Only

behind a router, firewall, or security device manager that provides routing, firewall, wireless
support, and traffic meter features.
To configure the modem router as a DSL modem only:

Launch an Internet browser from a computer or WiFi device that is connected to the
network.
