Section 1 - Product Overview
Introduction
The COVR-3902 Covr Wi-Fi System is a revolutionary wireless networking solution comprised of the COVR-2600R AC2600 Wi-Fi Router
and COVR-1300E AC1300 Wi-Fi Range Extender. The Covr Wi-Fi System uses a high-power Wi-Fi router at its core to oer a “PowrZone” of
1
blazing fast 2533 Mbps
as you move through your home for up to 6,000 sq. ft of seamless whole home coverage. With the COVR-3902, D-Link has got you Covr’d.
Wi-Fi, while the Covr Seamless Extender takes care of the outer edge. Automatically connect to the strongest signal
Features
• High-Power Wi-FI - The COVR-3902 features a high-power AC2600 router oering blazing-fast wireless speeds
of up to a combined 2533 Mbps (1732 Mbps 802.11ac 5 GHz, plus 800 Mbps 802.11n 2.4 GHz)1 combined with
the AC1300 seamless extender to bring high-performance Wi-Fi to the hard-to-reach places in your home.
COVR-3902 provides you with the speed you need to fully enjoy data-intensive activities such as 4K video
steaming and online gaming.
• Smart Roaming - The Covr Wi-Fi System creates a single, seamless wireless network throughout your entire
home using a single wireless network name (SSID). This means that once you connect, your connection
is maintained seamlessly as you and your wireless device roam throughout your home, allowing you to
experience an uninterrupted connection without buering, drop-outs or dead spots.
• 4 x 4 MU-MIMO Technology - Multi-User MIMO (MU-MIMO) sends and receives data to and from multiple
devices simultaneously to increase speed and eciency. Your laptop, tablet, media player and game console
can all be sending and receiving data at the same time, with no need to wait in turn, allowing you to get more
out of your home Wi-Fi network than ever before.

Maximum wireless signal rate derived from IEEE Standard 802.11a, 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.
3D-Link COVR-3902 User Manual
Section 1 - Product Overview
• Smart Steering - Behind the scenes, the COVR-3902 automatically determines whether to connect a device to
the 2.4 or 5 GHz band, thereby providing the best speed and range for each device and optimally distributing
devices to each network.
• Expandable Network - Covr’s Wi-Fi System is pre-paired and works straight out of the box, so you just need to
plug them in and get started. Covr is also a scalable solution; extra extenders can be added to increase the reach
of your network. Scale up your Wi-Fi by adding another extender to get true whole-home coverage.
• Easy Setup - Through its intuitive web-based user interface or the free D-Link Wi-Fi app, you can quickly set up
the COVR-3902 and congure your network to your specic settings in a matter of minutes.

Installation
This section will walk you through the installation of the COVR-3902. During the setup procedure, your Internet connection will
be temporarily unavailable, until the setup process is completed.
Note: If you will be setting up the COVR-3902 AC3900 Whole Home Wi-Fi System on your mobile device using the free D-Link
Wi-Fi app, you must download this app before beginning the installation process.
To get the D-Link Wi-Fi app, browse the App Store for Apple devices or the Google Play store and search for D-Link Wi-Fi. You
can also scan the QR code below, which will take you to the respective D-Link Wi-Fi app store page directly.

Section 2 - Installation
Before you Begin
• Placement of the router is very important. Do not place the router in an enclosed area such as a closet, cabinet,
attic, or garage.
• Congure the router with the computer that was last connected directly to your Internet connection. Verify that it
is connected to the Internet before connecting additional devices.
• If your ISP provided you with a modem/router combo, you will need to set it to “bridge” mode so the router can
work properly. Please contact your ISP or refer to the user manual for your modem/router device.
• You can only use the Ethernet port on your modem. If you were using the USB connection before using the router,
then you must turn o your modem, disconnect the USB cable and connect an Ethernet cable to the Internet
port on the router, and then turn the modem back on. In some cases, you may need to call your Internet Service
Provider (ISP) to change connection types (USB to Ethernet).
• If connecting to a DSL modem, 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 might be necessary to establish a connection.
• 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.
• If you have DSL and are connecting via PPPoE, make sure you disable or uninstall any PPPoE software such as
WinPoET, BroadJump, or EnterNet 300 from your computer or you will not be able to connect to the Internet.

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 3-90 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 (0.5 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 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 3-6 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 is not in use.

1. Attach the four included antennas to the sides and back of the router. The COVR-3902 system is designed to give you
the fastest, most stable network connection possible. In order to maximize performance, fully extend the side antennas
into a 45-degree angle and the rear antennas into a 90-degree angle to provide optimal wireless coverage. Keep the
router in an open area for better wireless coverage.
