The DSL-3788's USB sharing technology lets you take advantage of le sharing. Simply plug in a USB storage drive into the USB

port on the back of your DSL-3788 and you can access les, stream videos, view photos, or listen to music on your laptop or

mobile devices. The intuitive interface lets anyone immediately connect to a variety of entertainment options stored on your

own storage device.

The DSL-3788 provides incredible speeds, smart antenna technology, and fast ports.

Section 1 - Product Overview

• Faster Wireless Networking - The DSL-3785 features the updated 802.11ac Wave 2 specication, which

improves on the bandwidth, range, and speed of 802.11ac Wave 1, and can deliver up to 1200 Mbps* to your

wireless devices. It operates on both the 2.4 GHz and 5 GHz bands to allow separation of trac so users can

participate in high-bandwidth activities, such as video streaming, online gaming, and real-time audio, without

aecting low-priority trac like email and web surng.

• Compatible with 802.11n/g/b/a Devices - The DSL-3788 is still fully backwards compatible with the 802.11n,

802.11g, and 802.11a standards, so it can connect with existing 802.11n, 802.11g, 802.11b, and 802.11a wireless

devices.

• Advanced Features - The web-based user interface displays a number of advanced network management

features including:

• Filtering - Easily apply content ltering based on IP address, MAC address, URL, and/or domain

name.

• Scheduling - The rewall, wireless, and port forwarding features can be scheduled to be active on a

schedule you dene.

• User-friendly Setup Wizard - Through its easy-to-use web-based user interface, the DSL-3788 lets you control

what information is accessible to those on the wireless network, whether from the Internet, or from your

company’s server. Congure your router to your specic settings within minutes.

* Maximum wireless signal rate derived from IEEE Standard 802.11a, 802.11b, 802.11g, 802.11n, and 802.11ac 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-3788 Wireless

AC1200 Dual-Band Gigabit ADSL2+/VDSL2 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-3788 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-3788 will be providing this

functionality.

Section 2 - Installation

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 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 to 90 feet (1 to 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 (0.5 meters) thick, 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 to 6 feet or 1 to 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 is not in use.
