Product Overview
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

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
Product Description
Safety Instructions

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.TheWi-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.
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.
