Introduction
The D-Link AirPlus Xtreme G DI-824VUP Wireless Broadband Router is an
802.11g high performance, wireless router with two printer ports, one parallel
and one USB. It is an ideal way to extend the reach and number of computers
connected to your wireless network.
Unlikemost802.11grouters, the DI-824VUPiscapable ofdata transferspeeds
up to 54 Mbps*(compared to the standard 11 Mbps) when used with other D-
Link AirPlus Xtreme G products such as the DWL-G650 and DWL-G520
Wireless Adapters.
After completing the steps outlined in the Quick Installation Guide (included in
your package) you will have the ability to share information and resources, as
well as share a printer wirelessly on your network.
The DI-824VUP is compatible with most popular operating systems, including
Macintosh, Linux and Windows, and can be integrated into a large network.
This Manual is designed to help you connect the Router and D-Link AirPlus
2.4GHz Wireless Adapters into a network in Infrastructure mode. Please take
a look at the Getting Started section in this manual to see an example of an
Infrastructure networkusing the DI-824VUP.

D-Link AirPlus wireless products are based on industry standards to provide easy-to-
use and compatible high-speed wireless connectivity within your home, business, or
public access wireless networks. Strictly adhering to the IEEE standard, the D-Link
AirPlus wireless family of products will allow you to securely access the data you want,
whenandwhereyouwantit.Youwillbeabletoenjoythefreedomthatwirelessnetworking
delivers.
Awirelesslocal area network (WLAN) is acellular computer networkthat transmitsand
receives data with radio signals instead of wires. Wireless LANs are used increasingly
inboth home and office environments,and publicareas suchasairports,coffeeshops,
anduniversities.Innovativewaysto utilize WLAN technology are helping peopletowork
and communicate more efficiently. Increased mobility and the absence of cabling and

Wireless Basics
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
linktoaconventionalEthernetLAN inordertouseservers,printers,oranInternet
connectionsuppliedthrough the wiredLAN.AWireless Routerisa device used
to provide this link.
People use wireless LAN technology for many different purposes:
Mobility - Productivity increases when people have access to data in any
locationwithinthe operatingrangeof theWLAN.Management decisionsbased
on real-time information can significantly improve worker efficiency.
Low Implementation Costs – WLANs (Wireless LocalArea Networks) are
easyto setup, manage,change, andrelocate. Networksthatfrequentlychange,
both physically and logically, can benefit from WLANs ease of implementation.
WLANscanoperate inlocationswhere installationofwiring maybe impractical.
Installation Speed and Simplicity - Installing a wireless LAN system can
befast, easy,and caneliminate theneed topull cablethrough wallsand ceilings.
Network Expansion - Wireless technology allows the network to go where
wires cannot.
Scalability – Wireless LocalArea Networks (WLANs) can be configured in a
variety of topologies to meet the needs of specific applications or existing
infrastructure. Configurations are easily changed and range from peer-to-peer
networks suitable for a small number of users to larger infrastructure networks
to accommodate hundreds or thousands of users, depending on the number
of wireless devices deployed.

Wireless Basics
The DI-824VUP is compatible with other D-Link AirPlus Xtreme G 802.11g
products, which include:
♦Enhanced 2.4GHz Wireless Cardbus Adapters used with laptop
computers (DWL-G650)
♦Enhanced 2.4GHz Wireless PCI cards used with desktop computers
(DWL-G520)
Installation Considerations
TheD-LinkAirPlusXtremeG+ DI-824VUPletsyouaccess your network,using
a wireless connection, from virtually anywhere. 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
dependingon thetypesofmaterialsandbackgroundRF(radiofrequency) 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 DI-824VUP and
your receiving device (e.g., the DWL-G650) to a minimum-each wall or
ceiling can reduce your D-Link AirPlus wireless product’s range from 3-90
feet (1-30 meters.) Position your receiving devices so that the number of
walls or ceilings is minimized.
2. Be aware of the direct line between routers and computers. 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!
Try to make sure that devices are positioned so that the signal will travel
straight through a wall or ceiling for better reception.
3. Building Materials make a difference - a solid metal door or aluminum
studs may have a negative effect on range. Try to position wireless
devices and computers with wireless adapters so that the signal passes
through drywall or open doorways and not other materials.
4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical
devices or appliances that generate RF noise.
Based on the IEEE 802.11g standard, the DI-824VUP is interoperable with
existing compatible 2.4GHz wireless technology with data transfer speeds of
up to 54Mbps (with the D-Link AirPlus Xtreme G family of wireless devices,) as
wellasstandard802.11btechnology( theD-LinkAirfamilyof wirelessdevices),
with speeds of up to 11Mbps.
Standards-Based Technology

With a single IPAddress from your Broadband Internet Service provider you
can share the Internet with all the computers on your local network, without
sacrificing speed or security, using D-Link Air networking products.
Getting Started
An Infrastructure wireless network contains an Access Point. The
Infrastructure Network example, shown here, contains the following D-Link
network devices:
A wireless Broadband Router -
D-Link AirPlus Xtreme G DI-824VUP
A laptop computer with a wireless adapter -
D-Link AirPlus Xtreme G DWL-G650
A desktop computer with a wireless adapter -
D-Link AirPlus Xtreme G DWL-G520
A Cable modem -
D-Link DCM-201
Ifyouneed to assign IPAddresses tothecomputers on thenetwork,please
remember that the IP Address for each computer must be in the same
IP Address range as all the computers in the network, and the Subnet
Mask must be exactly the same for all the computers in the network.
For example: If the first computer is assigned an IPAddress of 192.168.0.2
with a Subnet Mask of 255.255.255.0, then the second computer can be
assignedanIPAddressof192.168.0.3withaSubnetMaskof255.255.255.0,
etc.
IMPORTANT: If computers or other devices are assigned the same IP
Address, one or more of the devices may not function properly on
the network.
IP ADDRESS
With its default settings, the DI-824VUP will connect with other
D-Link Air or AirPlus products, right out of the box.
Note: If you are using a DHCP-capable router in your network setup, such
as the DI-824VUP, you will not need to assign a static IPAddress.

Pleaseremember that D-Link AirPlus wirelessdevices are pre-configured toconnect
together, right out of the box, with their default settings.
