Installation
This section will walk you through the installation process. Placement of the Router is very important. Do not place the Router in an enclosed area
such as a closet, cabinet, or in the attic or garage.
Before You Begin
Please read and make sure you understand all the prerequisites for proper installation of your new Router. Have all the necessary information and
equipment on hand before beginning the installation.

Installation Notes
In order to establish a connection to the Internet it will be necessary to provide information to the Router that will be stored in its memory. For some
users, only their account information (Username and Password) is required. For others, various parameters that control and define the Internet
connection will be required. You can print out the two pages below and use the tables to list this information. This way you have a hard copy of all
the information needed to setup the Router. If it is necessary to reconfigure the device, all the necessary information can be easily accessed. Be
sure to keep this information safe and private.
Low Pass Filters
Since ADSL and telephone services share the same copper wiring to carry their respective signals, a filtering mechanism may be necessary to
avoid mutual interference. A low pass filter device can be installed for each telephone that shares the line with the ADSL line. These filters are easy
to install passive devices that connect to the ADSL device and/or telephone using standard telephone cable. Ask your service provider for more
information about the use of low pass filters with your installation.
Operating Systems
The DSL-2750U uses an HTML-based web interface for setup and management. The web configuration manager may be accessed using any
operating system capable of running web browser software, including Windows 98 SE, Windows ME, Windows 2000, Windows XP, and Windows
Vista.
Web Browser
Any common web browser can be used to configure the Router using the web configuration management software. The program is designed to
work best with more recently released browsers such as Opera, Microsoft Internet Explorer® version 6.0, Netscape Navigator® version 6.2.3, or
later versions. The web browser must have JavaScript enabled. JavaScript is enabled by default on many browsers. Make sure JavaScript has not
been disabled by other software (such as virus protection or web user security packages) that may be running on your computer.
Ethernet Port (NIC Adapter)
Any computer that uses the Router must be able to connect to it through the Ethernet port on the Router. This connection is an Ethernet connection
and therefore requires that your computer be equipped with an Ethernet port as well. Most notebook computers are now sold with an Ethernet port
already installed. Likewise, most fully assembled desktop computers come with an Ethernet NIC adapter as standard equipment. If your computer
does not have an Ethernet port, you must install an Ethernet NIC adapter before you can use the Router. If you must install an adapter, follow the
installation instructions that come with the Ethernet NIC adapter.
