Section 1 - Product Overview
Introduction
The D-Link DAP-1720 AC1750 Wi-Fi Range Extender extends your Internet connection over a blazing-fast Gigabit Wireless AC
connection of up to 1750 Mbps (Up to 1300 Mbps via 5 GHz Wireless AC and up to 450 Mbps via 2.4 GHz Wireless N)1, by using
advanced AC beamforming technology to maximize the speed and range of your wireless signal. The DAP-1720 connects with your
existing networking equipment to extend the range and enhance the capabilities of your home or oce network. This means you
can bring Wi-Fi to places where your current signal doesn’t reach, letting you move from room to room, oce to oce, oor to oor,
or yard to yard without losing signal. Enjoy Wi-Fi on your porch, balcony, next to your pool, breakroom, the far end of your oce,
or in your basement. The DAP-1720 prepares your home to become a Connected Home by allowing you to install more wireless
surveillance cameras, baby monitors, sensors, and alarms in the places where you want rather just where your old signal reached.
Featuring a 3x3 MIMO antenna conguration, the DAP-1720 oers better data rates, fewer dead-spots, more coverage, and higher
reliability. Operating exclusively in the 5 GHz band, the DAP-1720’s 802.11ac wireless connections avoid crowded 2.4 GHz band trac,
giving you faster speeds while still maintaining backwards compatibility with older 802.11n/g/b devices. The DAP-1720’s superior
design allows you to enjoy full motion, high denition video calls on your mobile device while moving around. Equipped with a
Gigabit LAN/Internet port to provide speeds up to 10x faster than standard 10/100 ports, the DAP-1720 creates the best networking
experience to date.
The DAP-1720 AC1750 Wi-Fi Range Extender features D-Link’s Smart Signal LED technology, which makes nding the optimal location
for your extender a cinch. With other range extenders, it is dicult or impossible to gauge how strong or weak the connection between
an extender and an uplink network is, but the DAP-1720’s Smart Signal LEDs eliminate the guesswork by giving you instant visual
feedback so you can quickly test out multiple locations to nd the best place for the DAP-1720.

Section 1 - Product Overview
What is a Wireless Extender?
The DAP-1720 acts as a repeater to extend the range of an existing wireless network to provide a better signal for parts of your
home or oce that may have poor or no reception. The DAP-1720 will rebroadcast your existing wireless signal allowing you
to reach the farthest corners of your home or oce. The extended network can simply use the same network credentials as the
existing network, or you can specify a dierent network name and password, giving you the exibility to control network access.
You may also use the DAP-1720 as a wireless access point by connecting an Ethernet cable.

Wireless Installation Considerations
The DAP-1720 lets you extend your existing wireless network’s coverage as long as it is within range of the uplink network. Keep in mind
that the DAP-1720’s range may be limited by the number, thickness and location of walls, ceilings, or other objects that the wireless
signals must pass through. Typical ranges vary depending on the types of materials and background radio frequency (RF) 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 DAP-1720 and other network devices to a minimum each wall or ceiling can reduce your adapter’s range from 1 to 30 meters (3 to 90 feet). 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 0.5 meters (1.5 feet thick), at a 45-degree
angle appears to be almost 1 meter (1.5 feet) thick. At a 2-degree angle it looks over 14 meters (42 feet) 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 extenders, 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 at least 1 to 2 meters (3 to 6 feet) away 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.

14D-Link DAP-1720 User Manual
Section 3 - Conguration
WPS Conguration
Wireless Protected Setup (WPS) makes connecting your DAP-1720 easy. To use WPS, rst make sure the source router or access point
features a WPS Button or has a virtual WPS Button.
Step 1 - Initiate WPS Mode
While the Status/WPS LED is blinking amber, push the WPS button on the source
wireless router or AP, and then push the WPS button on the DAP-1720. The Status/
WPS LED will start to ash green. Please allow up to two minutes for the process to
nish. The Status/WPS LED will turn solid green when the DAP-1720 has connected
successfully to the source wireless router or access point.
Step 2 - Connecting Devices to the DAP-1720
The DAP-1720 is now ready to share the extended Wi-Fi network with your PCs and
mobile devices. You may use the WPS method to connect devices to the extended
network created by the DAP-1720 using the following network names (SSID). The
password will be the same as the wireless network you are extending.
• (Your router’s SSID)-EXT
• (Your router’s SSID)-EXT5Ghz
When connecting to your extended network, you can choose to connect either to
the 2.4 GHz or 5 Ghz extension. Note that 802.11ac speeds are only available over
5 Ghz.
15D-Link DAP-1720 User Manual
Section 2 - Installation
Optimize Extender Location
The Status/WPS LED will turn solid green when the DAP-1720 has connected successfully to a wireless network and is extending that
network. If the Smart Signal LED has a single amber bar after the connection process has nished, the DAP-1720 has established a poor
quality connection. The more lit bars on the Signal Indicator LED, the better the wireless signal. To improve the connection quality,
the DAP-1720 should be relocated closer to the source wireless router. If the extender has been congured as an Access Point and is
connected via Ethernet cable to an uplink network, the Smart Signal LED will not be lit.
