Product Overview Product Description The Verizon® D-Link® DSL-2750B Wireless Gateway provides reliable, high-speed, Internet access to your existing small office 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.
Networking Requirements The following system specifications are required for optimum performance of the Router via 10/100 Ethernet or 802.11n/g wireless. ETHERNET: • Pentium® or equivalent class machines or higher • Microsoft® Windows® (7,Vista®, XP, 2000, ME, NT 4.0, 98 SE) Mac OS® X, or Linux installed • 64 MB RAM (128 MB recommended) • 10 MB of free hard drive space • 10/100 Base-T Network Interface Card (NIC) • Internet Explorer® 6.0, Firefox® 3.0, Safari® 3.0 or Chrome 2.
Hardware Features LED Indicators This section explains the LED states and descriptions. LED indicators are used to verify the unit’s operation and status. 1 Power 2 Ethernet (1-4) 3 Wireless 4 USB 5 DSL 6 Internet A solid green light indicates the unit is powered on. A red light indicates a malfunction. A solid light indicates a connection to an Ethernet-enabled computer on ports 1-4. This LED blinks during data transmission.
Installation This section will explain how to configure your computers to connect to the gateway, configure the gateway to connect to the Internet, and set up your wireless clients. DSL Filters/Microfilters 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.
