Product Overview

Product Description

The Verizon® D-Link® DSL-2750B Wireless Gateway provides reliable, high-speed, Internet access to your
existing small oce phone line and is capable of data rates hundreds of times faster than a traditional analog
modem. But unlike analog modems, the Gateway allows you to use the same phone line for simultaneous
voice/fax communications and high-speed Internet access, eliminating the need for dedicated phone lines
for voice and data needs. In addition, it supports a variety of networking interfaces along with the following
optional features:

• Four 10/100 Ethernet Ports

• 802.11n wireless technology to provide the best wireless performance

• Advanced rewall features including parental control, access control, and content ltering

• Wi-Fi Protected Setup (WPS) Push Button/PIN setup

• UPnP Support

• USB port for sharing music/video/images using a thumb drive or external hard drive

Safety Instructions

• Never install any telephone wiring during a lightning storm.

• Never install telephone jacks in wet locations unless the jack is specically designed for wet
locations.

• Never touch non-insulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.

• Use caution when installing or modifying telephone lines.

WARNING: Risk of electric shock. Voltages up to 140 Vdc (with reference to ground) may be present on
telecommunications circuits.

Installation

This section will explain how to congure your computers to connect to the gateway, congure the gateway
to connect to the Internet, and set up your wireless clients.

DSL Filters/Microlters

ADSL signals must be blocked from reaching each telephone, answering machine, fax machine, or any similar
conventional device. Failure to do so may degrade telephone voice quality and ADSL performance.

Install a microlter if you desire to use the DSL-equipped line jack for telephone, answering machine, fax
machine or other telephone device connections. Microlter installation requires no tools or telephone
rewiring. Just unplug the telephone device from the baseboard or wall mount and plug in a microlter and
then plug in the telephone device.

You can purchase microlters from your local electronics retailer, or contact the original provider of your DSL
equipment.

WPS

Wi-Fi Protected Setup (WPS) System is a simplied method for securing your wireless network during the
“Initial setup” as well as the “Add New Device” processes. The Wi-Fi Alliance (WFA) has certied it across dierent
products as well as manufactures. The process is just as easy, as pressing a button for the Push-Button Method
or correctly entering the 8-digit code for the Pin-Code Method. The time reduction in setup and ease of use
are quite benecial, while the highest wireless Security setting of WPA2 is automatically used.

Push Button

Step 1: Select Push Button from the drop-down and then click the Go button to start the WPS process.

Step 2: Within 2 minutes, press the WPS button on your wireless client. Some clients may require you to launch its

software utility and click a WPS button. Please refer to your wireless client’s user guide for more information.

Step 3: Allow 1-2 minutes for the devices to communicate. Once complete your client will connect to the gateway.

Client PIN Code

A PIN is a unique number that can be used to add the router to an existing network or to create a new network.
You will need to get the PIN number from one of your wireless clients. Please refer to your wireless client’s user
guide for more information.

Step 1: From your wireless client, write down the PIN and activate/start the WPS process.

Step 2: Within 2 minutes from the Gateway, select Client Pin Code from the drop-down, enter the PIN number

in the box, and then click the Go button.

Step 3: Allow 1-2 minutes for the devices to communicate. Once complete your client will connect to the gateway.

IP Address Distribution (DHCP)

DHCP stands for Dynamic Host Control Protocol. The Gateway has a built-in DHCP server. The DHCP Server will
automatically assign an IP address to the computers /devices on the LAN/private network. Be sure to set your
computers to be DHCP clients by setting their TCP/IP settings to “Obtain an IP Address Automatically.” When
you turn your computers on, they will automatically load the proper TCP/IP settings provided by the Gateway.
The DHCP Server will automatically allocate an unused IP address from the IP address pool to the requesting
computer/device. You must specify the starting and ending address of the IP address pool (refer to the next
page).

Firewall Settings

Overview

This section explains how to congure your Router’s rewall security features. The Router’s rewall security
settings allow you reduce the risk of unauthorized access to your network by prohibiting certain types of
inbound and outbound network trac and by allowing you to congure specic rewall rules.

To change your rewall security level, click the option next to the desired security setting. Next, click Apply to
allow the changes to take eect.

Maximum Security

(High):

Typical Security

(Medium):

Minimum Security

(Low):

High security level only allows basic Internet functionality. Only Mail, News, Web, FTP, and
IPSEC are allowed. All other trac is prohibited.

Like High security, Medium security only allows basic Internet functionality by default.
However, Medium security allows customization through NAT conguration so that you can
enable the trac that you want to pass.

Low security setting will allow all trac except for known attacks. With Low security, your
Gateway is visible to other computers on the Internet.

DMZ Host

If an application has trouble working from behind the Gateway, you can expose one computer to the Internet

Port Triggering

The Port Triggering feature allows you to forward a range of ports to an IP address on your local network (LAN)
only after specic outbound trac is detected. You can set up a port triggering entry based on your specic
ports.

IMPORTANT: Using various Internet applications depends on the Router’s rewall settings. Make sure that the
Router’s rewall is set to Medium Security or lower to take advantage of all the port forwarding features.
Firewall settings take precedence over port forwarding services congured in the Router. For example, if the
rewall is set to Medium Security, this will block ICMP packets even if the ICMP service is enabled. If a port
forwarding service is not working, try setting the rewall to a lower setting.

Check your IP address

After you install your new D-Link wireless adapter and have established a wireless connection, by default, the
TCP/IP settings should be set to obtain an IP address from a DHCP server (i.e., router) automatically. To verify your
IP address, please follow the steps below.

Windows® 8 Users

• Press the Windows key and R together. Type cmd in the box
and click OK.

• At the prompt, type ipcong and press Enter.

• This will display the IP address, subnet mask, and default
gateway of your adapter.

Windows® 7/Vista® Users

• Click Start, type cmd in the search box and then click OK.

• At the prompt, type ipcong and press Enter.

• This will display the IP address, subnet mask, and default
gateway of your adapter.

Windows® XP Users

• Click on Start > Run. In the run box type cmd and click OK.

• At the prompt, type ipcong and press Enter.

• This will display the IP address, subnet mask, and the default
gateway of your adapter.

If the address is 0.0.0.0, check your adapter installation, security settings, and the settings on your router.
Some rewall software programs may block a DHCP request on newly installed adapters.
