company’s server. Congure your router to your specic settings within minutes.
* Maximum wireless signal rate derived from IEEE Standard 802.11a, 802.11b, 802.11g, 802.11n, and 802.11ac specications. Actual data throughput will vary. Network conditions
and environmental factors, including volume of network trac, building materials and construction, and network overhead, lower actual data throughput rate. Environmental
conditions will adversely aect wireless signal range.

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-3782 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.
Before you Begin
• 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 conguration 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-3782 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-3782 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 dierence. A solid metal door or aluminum studs may have a negative eect 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.

button (or a software utility with WPS) that you can press to connect to the DSL-3782 router. Please refer to your user manual
for the wireless device you want to connect to make sure you understand how to enable WPS. Once you know, follow the steps
below:
Step 1 - Press the WPS button on the DSL-3782 for about 5 seconds. The WPS LED on the front will start to blink.

Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DSL-3782. Read the
following descriptions if you are having problems. The examples below are illustrated in Windows® XP. If you have a dierent
operating system, the screenshots on your computer will look similar to these examples.
1. Why can’t I access the web-based conguration utility?
When entering the IP address of the D-Link router (192.168.1.1 for example), you are not connecting to a website, nor do you
have to be connected to the Internet. The device has the utility built-in to a ROM chip in the device itself. Your computer must
be on the same IP subnet to connect to the web-based utility.
• Make sure you have an updated Java-enabled web browser. We recommend the following:
• Internet Explorer 8 or higher
• EDGE Browser 20 or higher
• Firefox 20 or higher
• Safari 4 or higher
• Chrome 17 or higher
• Verify physical connectivity by checking for solid link lights on the device. If you do not get a solid link light, try using a
dierent cable, or connect to a dierent port on the device if possible. If the computer is turned o, the link light may not be
on.
• Disable any Internet security software running on the computer. Software rewalls such as ZoneAlarm, BlackICE, Sygate,
®
Norton Personal Firewall, and Windows
included with your rewall software for more information on disabling or conguring it.
XP rewall may block access to the conguration pages. Check the help les
94D-Link DSL-3782 User Manual
Section 7 - Troubleshooting
• Congure your Internet settings:
• Go to Start > Settings > Control Panel. Double-click the Internet Options Icon. From the Security tab, click
the button to restore the settings to their defaults.
• Click the Connection tab and set the dial-up option to Never Dial a Connection. Click the LAN Settings button.
Make sure nothing is checked. Click OK.
• Go to the Advanced tab and click the button to restore these settings to their defaults. Click OK three times.
• Close your web browser (if open) and open it.
• Access the web management. Open your web browser and enter the IP address of your D-Link router in the address bar. This
should open the login page for your web management.
• If you still cannot access the conguration, unplug the power to the router for 10 seconds and plug back in. Wait about 30
seconds and try accessing the conguration. If you have multiple computers, try connecting using a dierent computer.
2. What can I do if I forgot my password?
If you forgot your password, you must reset your router. This process will change all your settings back to the factory defaults.
To reset the router, locate the reset button (hole) on the rear panel of the unit. With the router powered on, use a paperclip
to hold the button down for 10 seconds. Release the button and the router will go through its reboot process. Wait about 30
seconds to access the router. The default IP address is 192.168.1.1. When logging in, enter the device password shown on
device label.

3. Why can’t I connect to certain sites or send and receive emails when connecting through my router?
If you are having a problem sending or receiving email, or connecting to secure sites such as eBay, banking sites, and Hotmail,
we suggest lowering the MTU in increments of ten (Ex. 1492, 1482, 1472, etc).
To nd the proper MTU Size, you’ll have to do a special ping of the destination you’re trying to go to. A destination could be
another computer, or a URL.
• Click on Start and then click Run.
• Windows® 95, 98, and Me users type in command (Windows® NT, 2000, XP, Vista®, and 7 users type in cmd) and
press Enter (or click OK).
• Once the window opens, you’ll need to do a special ping. Use the following syntax:
ping [url] [-f] [-l] [MTU value]
Example: ping yahoo.com -f -l 1472
