Section 1 - Product Overview
Introduction
The AC1300 MU-MIMO Wi-Fi Nano USB Adapter (DWA-181) delivers powerful wireless AC technology to your desktop or notebook computer.
Simply plug the adapter into an available USB port and connect to a wireless network to access a secure, high-speed internet connection – 2.4GHz
(400Mbps) or 5GHz (up to 867Mbps). And with integrated Dual Band technology, you’ll have reduced Wi-Fi interference to maximize throughput
for faster streaming, gaming, and Skype calls.
Interference-Free Bandwidth
The AC1300 MU-MIMOWi-Fi Nano USB Adapter (DWA-181) delivers Dual Band technology to your home network for intelligent, versatile, interference-
free bandwidth. Check your email and surf the Internet on the 2.4GHz band; or game, make Skype calls and stream HD movies to multiple devices
using the cleaner, interference-free 5GHz band. Whatever you like to do online, Dual Band has you covered.
Compatible With All Your Wireless Products
While the AC1300 MU-MIMO Wi-Fi Nano USB Adapter delivers cutting-edge 802.11ac speed to your home network, it’s also backward compatible
with all of your current wireless products – no updates or adapters necessary.
What is wireless AC?
802.11ac is a new networking standard that produces high-throughput wireless speed on the 5GHz band. What does this mean for your home
network? Flawless HD video streaming, faster gaming, and lag-free Skype and Facetime calls, all with less Wi-Fi interference for smooth, lightning-
fast performance. And while your home gains all the cutting-edge bene ts of 11ac, D-Link’s AC1300 MU-MIMO Wi-Fi Nano USB Adapter is also
compatible with all of your current Wireless N products.
“Maximum wireless signal rate derived from IEEE 802.11ac specication and IEEE Standard 802.11n specication. D-Link makes no warranties as to forward compatibility with future standards or compatibility with 802.11ac
devices from other manufacturers. 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 factors may adversely aect wireless signal range. Up to 867Mbps wireless speeds achieved when connecting to other 802.11ac devices. Data throughput may also be
limited by the product’s interface, less than 480 Mbps for a USB 2.0 interface. The inclusion of a specic product or manufacturer does not imply its endorsement of D-Link or the D-Link product. Computer must adhere
to Microsoft’s recommended System Requirements.”

Installation
This section will walk you through the installation process. If you have a built-in wireless adapter, please disable it in device manager before installing
your D-Link adapter. Also, if you have previously installed another wireless adapter, please make sure any software is uninstalled.
Getting Started
Before installing your new D-Link wireless adapter, please verify the following:
• Remove any previous installations of wireless adapters
• Disable any built-in wireless adapters
• Verify the settings such as the SSID and security settings of the network(s) you want to connect to
Remove Existing Installations
If you’ve installed a dierent manufacture’s adapter or a dierent model D-Link adapter, make sure the software is uninstalled before installing
the new software. Some utilities may cause a conict with the new software. If you plan to use multiple adapters at dierent times, make sure the
utilities are not set to load when your computer boots up.
To remove any old software:
Windows 10 users: Click Start > All apps > Windows System > Control Panel > Programs > Uninstall a Program
Windows 7/8 users: Click Start > Control Panel > Uninstall Programs

Wireless Installation Considerations
The D-Link wireless adapter 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 adapter 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 2.4GHz 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 2.4GHz 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.

Section 5 - Wireless Security
Wireless Security
This section will show you the dierent levels of security you can use to protect your data from intruders. The DWA-181 oers the following types
of security:
• WPA/WPA2-Personal
• WPA/WPA2-Enterprise
What is WPA™?
WPA™, or Wi-Fi®Protected Access, is a Wi-Fi standard that was designed to improve the security features of WEP (Wired Equivalent Privacy).
The 2 major improvements over WEP:
• Improved data encryption through the Temporal Key Integrity Protocol (TKIP). TKIP scrambles the keys using a hashing algorithm
and, by adding an integrity-checking feature, ensures that the keys haven’t been tampered with. WPA2™is based on 802.11i and
uses Advanced Encryption Standard instead of TKIP.
• User authentication, which is generally missing inWEP, through the extensible authentication protocol (EAP).WEP regulates access
to a wireless network based on a computer’s hardware-specic MAC address, which is relatively simple to be snied out and stolen.
EAP is built on a more secure public-key encryption system to ensure that only authorized network users can access the network.
WPA/WPA2-Personal uses a passphrase or key to authenticate your wireless connection. The key is an alpha-numeric password between 8 and 63
characters long. The password can include symbols (!?*&_) and spaces. This key must be the exact same key entered on your wireless router or
access point.
WPA/WPA2-Enterprise incorporates user authentication through the Extensible Authentication Protocol (EAP). EAP is built on a more secure public
key encryption system to ensure that only authorized network users can access the network.
