vii
Security for wireless communication can be accomplished in a number of ways. The DSL-2740B supports WPA (Wi-Fi
Protected Access), WPA2, and mixed WPA/WPA2. Wireless access can also be controlled by selecting MAC addresses
that are allowed to associate with the device. Please read the section on Wireless Configuration.
Additional Software
It may be necessary to install software on your computer that enables the computer to access the Internet. Additional
software must be installed if you are using the device a simple bridge. For a bridged connection, the information needed
to make and maintain the Internet connection is stored on another computer or gateway device, not in the Router itself.
If your ADSL service is delivered through a PPPoE or PPPoA connection, the information needed to establish and
maintain the Internet connection can be stored in the Router. In this case, it is not necessary to install software on your
computer. It may however be necessary to change some settings in the device, including account information used to
identify and verify the connection.
All connections to the Internet require a unique global IP address. For bridged connections, the global IP settings must
reside in a TCP/IP enabled device on the LAN side of the bridge, such as a PC, a server, a gateway device such as a
router or similar firewall hardware. The IP address can be assigned in a number of ways. Your network service provider
will give you instructions about any additional connection software or NIC configuration that may be required.

Modulation Type ADSL uses various standardized modulation techniques to
transmit data over the allotted signal frequencies. Some
users may need to change the type of modulation used for
their service. The default DSL modulation (ADSL2+ Multi-
Mode) used for the Router automatically detects all types of
ADSL, ADSL2, and ADSL2+ modulation. However, if you are
instructed to specify the modulation type used for the
