Section 1 - Product Overview
Introduction
The D-Link DIR-842 is a IEEE 802.11ac compliant device that delivers up to 3x faster speeds than 802.11n while staying backward
compatible with 802.11n/g/b/a devices. Connect the DIR-842 to a cable or DSL modem and provide high-speed Internet access
to multiple computers, game consoles, and media players. Create a secure wireless network to share photos, les, music, videos,
printers, and network storage. Powered by the 802.11ac technology and equipped with four external antennas, this router
provides superior wireless coverage for larger homes and oces, or for users running bandwidth-intensive applications. The
DIR-842 also includes a 4-port 10/100/1000 Gigabit Ethernet switch that connects to wired devices for uninterrupted video
calling and faster le transfers.
D-Link Intelligent QoS Technology helps to increase network eciency by analyzing wired and wireless network trac and
prioritizing it in order of importance. This way, important network trac such as VoIP and video streaming, take priority over
background network trac such as a le downloads and print tasks, ensuring you have optimal network performance.
The DIR-842 supports the latest wireless security features to help prevent unauthorized access, be it from over a wireless network

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, 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

This section will allow you to prioritize particular clients over others, so that those
clients receive higher bandwidth. For example, if one client is streaming a movie
and another is downloading a non-urgent le, you might wish to assign the former
device a higher priority than the latter so that the movie streaming is not disrupted
by the trac of the other devices on the network.

Under All Devices, you will see device cards representing each connected client. If
some are o-screen, you can use the < and > buttons to scroll through the cards.
A maximum of one device can be assigned Highest priority.
A maximum of two devices can be assigned High priority.
A maximum of eight devices can be assigned Medium priority.
If no devices are explicitly assigned a priority, they will all be treated with equal
priority. If some devices are not assigned a priority and others are, the unassigned
devices will be treated with the lowest priority.
To assign a priority level to a device, drag the device card from the All Devices list

Increased mobility and the absence of cabling and other xed infrastructure have proven to be benecial for many users.
Wireless users can use the same applications they use on a wired network. Wireless adapter cards used on laptop and desktop
systems support the same protocols as Ethernet adapter cards.
Under many circumstances, it may be desirable for mobile network devices to link to a conventional Ethernet LAN in order to
use servers, printers or an Internet connection supplied through the wired LAN. A wireless router is a device used to provide

Bluetooth is the industry standard wireless technology used for WPAN. Bluetooth devices in WPAN operate in a range up to
30 feet away.
Compared to WLAN the speed and wireless operation range are both less than WLAN, but in return it doesn’t use nearly as
much power which makes it ideal for personal devices, such as mobile phones, PDAs, headphones, laptops, speakers, and other
devices that operate on batteries.

Where is wireless used?
Wireless technology is expanding everywhere not just at home or oce. People like the freedom of mobility and it’s becoming
so popular that more and more public facilities now provide wireless access to attract people. The wireless connection in public
places is usually called “hotspots”.
Using a D-Link CardBus Adapter with your laptop, you can access the hotspot to connect to Internet from remote locations
like: airports, hotels, coee shops, libraries, restaurants, and convention centers.
Wireless network is easy to setup, but if you’re installing it for the rst time it could be quite a task not knowing where to start.
That’s why we’ve put together a few setup steps and tips to help you through the process of setting up a wireless network.
Tips
Here are a few things to keep in mind, when you install a wireless network.
$FOUSBMJ[FZPVSSPVUFSPSBDDFTTQPJOU
Make sure you place the router/access point in a centralized location within your network for the best performance. Try to
place the router/access point as high as possible in the room, so the signal gets dispersed throughout your home. If you have
a two-story home, you may need a repeater to boost the signal to extend the range.
Eliminate Interference
Place home appliances such as cordless telephones, microwaves, and televisions as far away as possible from the router/access
point. This would signicantly reduce any interference that the appliances might cause since they operate on same frequency.
95D-Link DIR-842 User Manual
Appendix A - Wireless Basics
Security
Don’t let you next-door neighbors or intruders connect to your wireless network. Secure your wireless network by turning on
the WPA or WEP security feature on the router. Refer to product manual for detail information on how to set it up.
There are basically two modes of networking:
t Infrastructure – All wireless clients will connect to an access point or wireless router.
t "E)PD – Directly connecting to another computer, for peer-to-peer communication, using wireless network
adapters on each computer, such as two or more wireless network CardBus adapters.
An Infrastructure network contains an access point or wireless router. All the wireless devices, or clients, will connect to the
wireless router or access point.
An ad-hoc network contains only clients, such as laptops with wireless CardBus adapters. All the adapters must be in ad-hoc
mode to communicate.
