Chapter 5 Configuring Advanced Settings
802.11b/g Mode
Access to the Modems network can be restricted to wireless clients using either the
802.11b or 802.11g wireless adapters. Click on the down arrow next to the text box
and select the desired option. Actiontec recommends using the “Mixed” mode (the
default option), which enables both 802.11b and 802.11g wireless clients to join the
network.
After changing settings, click Next or Back to continue, or Save and Restart to
make all changes permanent.

DHCP Server

Selecting DHCP Server in the Advanced Settings screen generates the DHCP
Server screen. The Modem has a built-in DHCP (Dynamic Host Configuration
Protocol) server that automatically assigns a different IP address to each computer
on the network, eliminating IP address conflicts.
The factory default setting is On. To disable the DHCP Server, select Off.
Actiontec strongly recommends leaving the DHCP Server option On. If the DHCP
Server option is Off, ensure the IP addresses of the networked computers are
on the same subnet as the IP address of the Modem. For more information, see
DHCP Server Configuration.
