Section 1 - Product Overview
Introduction
The D-Link DIR-819 Wireless AC750 Dual Band Router shares your Internet connection over a blazing-fast wireless connection of up to 750 Mbps
(up to 433 Mbps over 5 GHzWireless AC and up to 300 Mbps over 2.4 GHz Wireless N)1, using advanced AC beamforming technology to signicantly
outperform 802.11n and other 802.11ac devices. Equipped with one Fast Ethernet WAN/Internet port and four Fast Ethernet LAN ports, the DIR-819
creates an excellent networking experience.
Featuring four antennas, the Wireless AC750 Dual Band Router oers better data rates, fewer dead-spots, more coverage, and higher reliability.
Operating exclusively in the 5 GHz band, the DIR-819’s 802.11ac wireless connections avoid the crowded 2.4 GHz band, giving you faster speeds while
still maintaining backwards compatibility with older 802.11n/g/b devices. A stronger Wi-Fi signal means you can install more wireless surveillance
cameras, baby monitors, sensors, and alarms in the places where you need them.
The DIR-819 supports the latest security features to help prevent unauthorized access. Support for WPA™ and WPA2™ standards ensure that you
will be able to use the best possible encryption regardless of your client devices. This router is also equipped with a dual-active rewall (SPI and
NAT) to prevent potential attacks over the Internet.
The DIR-819 is full of features to improve your home network. The rich parental controls allow you to easily control when the Internet should be
available in your home and what content is allowed. With all this and more, the DIR-819 Wireless AC750 Dual Band Router will serve your network
well for years to come.
1 Maximum wireless signal rate derived from IEEE Standard 802.11a, 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 1 - Product Overview
•ExcellentWireless Networking -The DIR-819 provides wireless speeds of up to a combined 750 Mbps (433 Mbps 802.11ac 5 GHz, plus
300 Mbps 802.11n 2.4 GHz)1. This capability rivals wired connections, allowing users to participate in real-time activities online, such
as HD video communication, online gaming, and use mobile devices from anywhere in your home while still oering full 802.11n/g/b
backward compatibility.
• Fast Wired LAN and WAN Networking - With four 10/100 Fast Ethernet LAN ports, and a 10/100 Fast Ethernet WAN port, the DIR-819
has an enormous amount of bandwidth to take full advantage of the highest speed broadband connections available.
• IPv6 Support - The DIR-819 fully supports IPv6 and includes support for a variety of IPv6 connection types including: SLAAC/DHCPv6,
6to4, 6rd, Static IPv6, IPv6 PPPoE, IPv6 in IPv4 tunneling, and local connectivity.
• Advanced Firewall Features - The web-based user interface displays a number of advanced network management features. Easily
apply content ltering based on MAC address, URL, and/or domain name. Schedule these lters to be active on certain days or for a
duration of hours or minutes.
• Secure Multiple/Concurrent Sessions - The DIR-819 can pass through VPN sessions. It supports multiple and concurrent IPSec and
PPTP sessions, so users behind the DIR-819 can securely access corporate networks.
• User-friendly Setup Wizard - Through its easy-to-use web-based user interface, the DIR-819 lets you quickly congure and secure
your router to your specic settings in minutes.

Section 2 - Installation
Before You Begin
Installation
• Placement of the router is very important. Do not place the router in an enclosed area such as a closet, cabinet, attic, or garage.
• Congure 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 Internet Service Provider (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 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
conguration 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
This D-Link wireless device 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 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 (3 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 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 1 to 2 meters (3 to 6 feet) 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. The DIR-819 is designed to give you the fastest, most stable network connection possible. In order to maximize performance, fully extend
the antennas to provide optimal wireless coverage. Keep the router in an open area for better wireless coverage.
2. Position your DIR-819 near your Internet-connected modem. Place it in an open area for better wireless coverage.
Hardware Setup
3. Turn o and unplug the power and Ethernet cable to your cable or DSL broadband modem. This is required. In some cases, you may need
to turn it o for up to ve minutes.

7. If you are conguring the DIR-819 wirelessly from a PC, connect to a Wi-Fi network printed on the included Wi-Fi conguration card. You
can also nd the Wi-Fi network names and passwords printed on the label attached to the bottom of your router.
8. If you are connecting to a broadband service that uses a dynamic connection (not PPPoE), you may be online already. Try opening a web
browser and connecting to a website. If the website does not load, proceed to Completing Setup on page 12.
If you are conguring the DIR-819 from a PC with a wired Ethernet connection, plug one end of an Ethernet cable into the port labeled
1 on the back of the router, and the other end into the Ethernet port on your computer.
