Section 1 - Product Overview
Introduction
The DSL-2790U Wireless N300 ADSL2+ Modem Router is a versatile, high-performance router for homes and small oces.
With integrated ADSL2/2+ supporting up to 24 Mbps download speeds, rewall protection, Quality of Service (QoS), 802.11n
wireless LAN and 4 Ethernet switch ports, this router provides all the functions that a home or small oce needs to establish
a secure and high-speed link to the outside world.
High-speed ADSL2/2+ Internet Connection - The latest ADSL2/2+ standards provide Internet transmission of up to 24 Mbps
downstream, 1 Mbps upstream.
High-performance Wireless - Embedded 802.11n technology for high-speed wireless connection, complete compatibility
with 802.11b/g wireless devices
Ultimate Wireless Connection with Maximum Security - This router maximizes wireless performance by connecting to
computer interfaces and staying connected from virtually anywhere at home and in the oce. The router can be used with
802.11b/g/n wireless networks to enable signicantly improved reception. It supports WPA/WPA2 and WEP for exible user
access security and data encryption methods.
Firewall Protection & QoS - Security features prevent unauthorized access to your home and oce network, be it from the
wireless devices or from the Internet. The router provides rewall security using Stateful Packet Inspection (SPI) and hacker
attack logging for Denial of Service (DoS) attack protection. SPI inspects the contents of all incoming packet headers before
deciding what packets are allowed to pass through. Router access control is provided with packet ltering based on port and
source/destination MAC/IP addresses. For Quality of Service (QoS), the router supports multiple priority queues to enable a
group of home or oce users to experience the benet of smooth network connection of inbound and outbound data without
concern for trac congestion. This QoS feature allows users to enjoy high-speed ADSL transmission for applications such as
VoIP and streaming multimedia over the Internet.
* Maximum wireless signal rate derived from IEEE Standard 802.11b, 802.11g, and 802.11n specications. Actual data throughput will vary. Network conditions and environmental
factors, including volume of network trac, building materials and construction, and network overhead, lower actual data throughput rate. Environmental conditions will
adversely aect wireless signal range.

4D-Link DSL-2790U Wireless N300 ADSL2+ Modem Router User Manual
Section 1 - Product Overview
• FasterWireless Networking -The DSL-2790U provides up to 300 Mbps* wireless connection with other 802.11n
wireless clients. This capability allows users to participate in real-time activities online, such as video streaming,
online gaming, and real-time audio.
• Compatible with 802.11b and 802.11g Devices -The DSL-2790U is still fully compatible with the IEEE 802.11b
and g standards, so you can use keep your existing 802.11b and g devices.
• Precise ATM Trac Shaping - Trac shaping is a method of controlling the ow rate of ATM data cells. This
function helps to establish Quality of Service for ATM data transfer.
• High Performance - Very high rates of data transfer are possible with the router-providing up to 24 Mbps
downstream for ADSL2+.
• Full Network Management - The DSL-2790U incorporates SNMP (Simple Network Management Protocol)
support for web-based management and text-based network management via a Telnet connection.
• Easy Installation - The DSL-2790U can be congured and managed easily using a web-based UI. Any common
web browser software can be used to manage the router.
• USB Support - The DSL-2790U provides a USB port for easy le sharing and printer sharing. The DSL-2790U
supports USB storage devices to share les through a SAMBA le server. It also supports sharing USB printers
to network members. Besides the sharing function, the DSL-2790U also supports connection to the Internet via
a USB 3G modem.
* Maximum wireless signal rate derived from IEEE Standard 802.11b, 802.11g, and 802.11n specications. Actual data throughput will vary. Network conditions and environmental
factors, including volume of network trac, building materials and construction, and network overhead, lower actual data throughput rate. Environmental conditions will
adversely aect wireless signal range.

Section 2 - Installation
Before you Begin
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, attic, or garage.
Note: This installation section is written for users who are setting up their home Internet service with the DSL-2790U
Wireless N300 ADSL2+ Modem Router for the rst time. If you are replacing an existing DSL modem and/or router, you may
need to modify these steps.
• Make sure to have your DSL service information provided by your Internet Service Provider handy.This information
is likely to include your DSL account's Username and Password.Your ISP may also supply you with additional WAN
conguration settings which are necessary to establish a connection. This information may include the connection
type (DHCP IP, Static IP, PPPoE, or PPPoA) and/or ATM PVC details.
• If you are connecting a considerable amount of networking equipment, it may be a good idea to take the time
to label each cable or take a picture of your existing setup before making any changes.
• We suggest setting up your DSL-2790U from a single device and verifying that it is connected to the Internet
before connecting additional devices.
• If you have DSL and are connecting via PPPoE, make sure you disable or uninstall any PPPoE connection software
such as WinPoET, BroadJump, or EnterNet 300 from your computer as the DSL-2790U will be providing this
functionality.

Wireless Installation Considerations
The D-Link wireless router lets you access your network using a wireless connection from virtually anywhere within the
operating range of your wireless network. Keep in mind, however, that the number, thickness and location of walls, ceilings,
or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary depending on the types
of materials and background RF (radio frequency) noise in your home or business. The key to maximizing wireless range is to
follow these basic guidelines:
1. Keep the number of walls and ceilings between the D-Link router and other network devices to a minimum - each wall or
ceiling can reduce your adapter’s range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or
ceilings is minimized.
2. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a 45-degree angle appears
to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters) thick! Position devices so that the
signal will travel straight through a wall or ceiling (instead of at an angle) for better reception.
3. Building materials make a dierence. A solid metal door or aluminum studs may have a negative eect on range. Try to
position access points, wireless routers, and computers so that the signal passes through drywall or open doorways. Materials
and objects such as glass, steel, metal, walls with insulation, water (sh tanks), mirrors, le cabinets, brick, and concrete will
degrade your wireless signal.
4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF noise.
5. If you are using 2.4 GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and home security systems),
your wireless connection may degrade dramatically or drop completely. Make sure your 2.4 GHz phone base is as far away
from your wireless devices as possible. The base transmits a signal even if the phone in not in use.
