Wireless Basics

D-Link wireless products are based on industry standards to provide easy-to­use and compatible high-speed wireless connectivity within your home,
business or public access wireless networks. Strictly adhering to the IEEE
standard, the D-Link wireless family of products will allow you to securely
access the data you want, when and where you want it. You will be able to
enjoy the freedom that wireless networking delivers.

A wireless local area network (WLAN) is a cellular computer network that
transmits and receives data with radio signals instead of wires. Wireless
LANs are used increasingly in both home and office environments, and public
areas such as airports, coffee shops and universities. Innovative ways to
utilize WLAN technology are helping people to work and communicate

more efficiently. Increased mobility and the absence of cabling and other
fixed infrastructure have proven to be beneficial 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 this link.

People use wireless LAN technology for many different purposes:

Mobility - Productivity increases when people have access to data in any

location within the operating range of the WLAN. Management decisions
based on real-time information can significantly improve worker efficiency.

Low Implementation Costs – WLANs (Wireless Local Area Networks)

are easy to set up, manage, change and relocate. Networks that frequently
change, both physically and logically, can benefit from WLANs ease of
implementation. WLANs can operate in locations where installation of wiring
may be impractical.

Installation Speed and Simplicity - Installing a wireless LAN system

can be fast and easy and can eliminate the need to pull cable through walls
and ceilings.

Network Expansion - Wireless technology allows the network to go where

wires cannot go.

Scalability – Wireless Local Area Networks (WLANs) can be configured in

a variety of topologies to meet the needs of specific applications and
installations. 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

1. The DI-774 is compatible with other D-Link Air Xpert A,B, and G

products, which include:

♦ 5GHz Wireless Cardbus Adapters used with laptop computers

(DWL-AG650)

♦ 5GHz Wireless PCI Adapters used with desktop computers

(DWL-AG520)

2. The DI-774 is also compatible with the D-Link AirPlusXtremeG 802.11g

wireless family, which includes :

♦ High-Speed 2.4GHz Wireless Cardbus Adapters used with laptop

computers (DWL-G650)

♦ High-Speed 2.4GHz Wireless PCI cards used with desktop

computers (DWL-G520)

3. The DI-774 is also compatible with the D-Link AirPlus 802.11b wireless

family, which includes :

Wireless Basics

OFDM reduces the amount of crosstalk (interference) in signal

transmissions. D-Link Air Xpert products will automatically sense the best
possible connection speed to ensure the greatest speed and range possible.

The DI-774 is also interoperable with existing compatible 2.4GHz wireless
devices with data transfer speeds of up to 54Mbps (with the D-Link
AirPlusXtremeG family of wireless devices,) as well as standard 802.11b
technology ( the D-Link AirPlus family of wireless devices), with speeds of up
to 11Mbps.

Installation Considerations

The D-Link Air Xpert DI-774 lets you access 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
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:

♦ High-Speed 2.4GHz Wireless Cardbus Adapters used with laptop

computers (DWL-650+)

♦ High-Speed 2.4GHz Wireless PCI cards used with desktop

computers (DWL-520+)

Standards-Based Technology

The versatile DI-774 Wireless Router integrates 802.11a , 802.11b and

802.11g standards into a single unit.
The 802.11a and 802.11g standards designate that devices may operate at

an optimal data rate of 54 Mbps. This means that in most environments,
within the specified range of this device, you will be able to transfer large files
quickly or even watch a movie in MPEG format over your network without
noticeable delays. This technology works by transmitting high-speed digital
data over a radio wave utilizing OFDM (Orthogonal Frequency Division
Multiplexing) technology. OFDM works by splitting the radio signal into
multiple smaller sub-signals that are then transmitted simultaneously at
different frequencies to the receiver.

1. Keep the number of walls and ceilings between the DI-774 and your
receiving device (e.g., the DWL-AG650) to a minimum each wall or ceiling

can reduce your D-Link Air Xpert 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.

Right out of the box, with its default settings, the DI-774

will connect with other D-Link Air, AirPlus,

AirXtremeG, and Air Xpert products.

With a single IP Address 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.

IP ADDRESS

Note: If you are using a DHCP-capable router in your network setup,
such as the DI-774, you will not need to assign a static IP Address.

If you need to assign IP Addresses to the computers on the network,

please remember that the

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 IP Address of

192.168.0.2 with a Subnet Mask of 255.255.255.0, then the second
computer can be assigned an IP Address of 192.168.0.3 with a Subnet
Mask of 255.255.255.0, etc.

IMPORTANT: If computers or other devices are assigned the same
IP Address, one or more of the devices may not be visible on the
network.

Tools> Admin

CTS (Clear To Send) is a function used to minimize collisions
among wireless devices on a wireless local area network
(LAN). CTS will make sure the wireless network is clear
before a wireless client attempts to send wireless data.
Enabling CTS will add overhead and may lower wireless
throughput.

CTS is typically used in a pure 802.11g environment. If CTS
is set to “None” in a mixed mode environment populated by

802.11b clients, wireless collisions may occur frequently.
CTS will always be used to make sure the wireless LAN is

clear before sending data.

Remote Management

Remote Management allows the DI-774 to be configured from the Internet by a web
browser. A username and password is still required to access the Web-Management
interface. In general, only a member of your network can browse the built-in web
pages to perform “Administrator” tasks. This feature enables you to perform
“Administrator” tasks from the remote (Internet) host.
IP Address: Internet IP address of the computer that has access to the Router. It is
not recommended that you set the IP address to * (star), because this allows any
Internet IP address to access the Router, which could result in a loss of security for
your network. If you elect to enable Remote Management, make sure to enter the
IP Address of the remote computer allowed to configure the DI-774.
Port: For security purposes, select a separate port number used to access the
Router. (The following is an example only; you may use a different port number.)
Example: http://x.x.x.x:8080 where x.x.x.x is the WAN IP address of the Router
and 8080 is the port used for the Web-Management interface.

Troubleshooting

This Chapter provides solutions to problems that can occur during the installation and
operation of the DI-774 Wireless Broadband Router. We cover various aspects of the
network setup, including the network adapters. Please read the following if you are
having problems.

Note: It is recommended that you use an Ethernet connection to

configure the DI-774 Wireless Broadband Router.

1.The computer used to configure the DI-774 cannot access the
Configuration menu.

Check that the Ethernet LED on the DI-774 is ON. If the

n

LED is not ON, check that the cable for the Ethernet
connection is securely inserted.

Check that the Ethernet Adapter is working properly. Please

n

see item 3 (Check that the drivers for the network
adapters are installed properly) in this Troubleshooting

section to check that the drivers are loaded properly.

n

Check that the IP Address is in the same range and subnet
as the DI-774. Please see Checking the IP Address in
Windows XP in the Networking Basics section of this
manual.

Note: The IP Address of the DI-774 is 192.168.0.1. All the computers on the
network must have a unique IP Address in the same range, e.g., 192.168.0.x.
Any computers that have identical IP Addresses will not be visible on the
network. They must all have the same subnet mask, e.g., 255.255.255.0

Do a Ping test to make sure that the DI-774 is responding.

n

Go to Start>Run>Type Command>Type ping 192.168.0.1.
A successful ping will show four replies.

Note: If you have
changed the default IP
Address, make sure to
ping the correct IP Ad­dress assigned to the
DI-774.

Troubleshooting

2. The wireless client cannot access the Internet in the
Infrastructure mode.

Make sure the wireless client is associated and joined with the correct Access

Point. To check this connection:

in the taskbar> select View Available Wireless Networks. The Connect to
Wireless Network screen will appear. Please make sure you have selected the

correct available network, as shown in the illustrations below.

Check that the IP Address assigned to the wireless adapter is within the

n

same IP Address range as the access point and gateway. (Since the
DI-774 has an IP Address of 192.168.0.1, wireless adapters must have
an IP Address in the same range, e.g., 192.168.0.x. Each device must
have a unique IP Address; no two devices may have the same IP
Address. The subnet mask must be the same for all the computers on
the network.) To check the IP Address assigned to the wireless adapter,

double-click on the Local Area Connection icon in the taskbar >
select the Support tab and the IP Address will be displayed. (Please

refer to Checking the IP Address in the Networking Basics section of
this manual.)

If it is necessary to assign a Static IP Address to the wireless adapter,

n

please refer to the appropriate section in Networking Basics. If you are
entering a DNS Server address you must also enter the Default

Gateway Address. (Remember that if you have a DHCP-capable
router, you will not need to assign a Static IP Address. See

Networking Basics: Assigning a Static IP Address. )

4. What variables may cause my wireless products to lose reception?

D-Link products let you access your network from virtually anywhere you want.
However, the positioning of the products within your environment will affect the
wireless range. Please refer to Installation Considerations in the Wireless
Basics section of this manual for further information about the most advanta­geous placement of your D-Link wireless products.

5. Why does my wireless connection keep dropping?

Antenna Orientation- Try different antenna orientations for the DI-774.

n

Try to keep the antenna at least 6 inches away from the wall or other
objects.

If you are using 2.4GHz cordless phones, X-10 equipment or other home

n

security systems, ceiling fans, and lights, your wireless connection will
degrade dramatically or drop altogether. Try changing the Channel on
your Router, Access Point and Wireless adapter to a different Channel
to avoid interference.

Keep your product away (at least 3-6 feet) from electrical devices that

n

generate RF noise, like microwaves, Monitors, electric motors, etc.

6. Why can’t I get a wireless connection?

To establish a wireless connection, while enabling Encryption on the DI-774,
you must also enable encryption on the wireless client.

7. Resetting the DI-774 to Factory Default Settings

After you have tried other methods for troubleshooting your network, you
may choose to Reset the DI-774 to the factory default settings.
Remember that D-Link Air Xpert products network together, out of the
box, at the factory default settings.

To hard-reset the D-Link Air Xpert DI-774 to Factory Default Settings, please
do the following:

n

Locate the Reset button on the back of the DI-774

Use a paper clip to press the Reset button

n

Hold for about 10 seconds and then release

n

For 802.11a, the Encryption settings are: 64, 128 or 152 bit. Make sure

n

that the encryption bit level is the same on the Router and the Wireless
Client.

For 802.11g, the Encryption settings are: 64, 128, or 152 bit. Make sure

n

that the encryption bit level is the same on the Router and the Wireless
Client.

Make sure that the SSID on the Router and the Wireless Client are exactly the
same. If they are not, wireless connection will not be established. Please note
that there are two separate SSIDs for 802.11a and 802.11g. The default SSID
for both 802.11a and 802.11g is default.

After the DI-774 reboots (this may take a few minutes)

n

it will be reset to the factory Default settings

Subject to the terms and conditions set forth herein, D-Link Systems, Inc. (“D-Link”) provides this Limited
warranty for its product only to the person or entity that originally purchased the product from:

• D-Link or its authorized reseller or distributor and

• Products purchased and delivered within the fifty states of the United States, the District of

Columbia, U.S. Possessions or Protectorates, U.S. Military Installations, addresses with an
APO or FPO.

Limited Warranty: D-Link warrants that the hardware portion of the D-Link products described
below will be free from material defects in workmanship and materials from the date of original retail
purchase of the product, for the period set forth below applicable to the product type (“Warranty
Period”), except as otherwise stated herein.

3-Year Limited Warranty for the Product(s) is defined as follows:

• Hardware (excluding power supplies and fans) Three (3) Years

• Power Supplies and Fans One (1) Year

• Spare parts and spare kits Ninety (90) days

D-Link’s sole obligation shall be to repair or replace the defective Hardware during the Warranty Period
at no charge to the original owner or to refund at D-Link’s sole discretion. Such repair or replacement will
be rendered by D-Link at an Authorized D-Link Service Office. The replacement Hardware need not be
new or have an identical make, model or part. D-Link may in its sole discretion replace the defective
Hardware (or any part thereof) with any reconditioned product that D-Link reasonably determines is
substantially equivalent (or superior) in all material respects to the defective Hardware. Repaired or
replacement Hardware will be warranted for the remainder of the original Warranty Period from the date
of original retail purchase. If a material defect is incapable of correction, or if D-Link determines in its sole
discretion that it is not practical to repair or replace the defective Hardware, the price paid by the original
purchaser for the defective Hardware will be refunded by D-Link upon return to D-Link of the defective
Hardware. All Hardware (or part thereof) that is replaced by D-Link, or for which the purchase price is
refunded, shall become the property of D-Link upon replacement or refund.

Limited Software Warranty: D-Link warrants that the software portion of the product (“Software”)
will substantially conform to D-Link’s then current functional specifications for the Software, as set forth
in the applicable documentation, from the date of original retail purchase of the Software for a period of
ninety (90) days (“Warranty Period”), provided that the Software is properly installed on approved
hardware and operated as contemplated in its documentation. D-Link further warrants that, during the
Warranty Period, the magnetic media on which D-Link delivers the Software will be free of physical
defects. D-Link’s sole obligation shall be to replace the non-conforming Software (or defective media)
with software that substantially conforms to D-Link’s functional specifications for the Software or to
refund at D-Link’s sole discretion. Except as otherwise agreed by D-Link in writing, the replacement
Software is provided only to the original licensee, and is subject to the terms and conditions of the
license granted by D-Link for the Software. Software will be warranted for the remainder of the original
Warranty Period from the date or original retail purchase. If a material non-conformance is incapable of
correction, or if D-Link determines in its sole discretion that it is not practical to replace the non­conforming Software, the price paid by the original licensee for the non-conforming Software will be
refunded by D-Link; provided that the non-conforming Software (and all copies thereof) is first returned
to D-Link. The license granted respecting any Software for which a refund is given automatically
terminates.

Non-Applicability of Warranty: The Limited Warranty provided hereunder for hardware and software
of D-Link’s products will not be applied to and does not cover any refurbished product and any product
purchased through the inventory clearance or liquidation sale or other sales in which D-Link, the sellers,
or the liquidators expressly disclaim their warranty obligation pertaining to the product and in that case,
the product is being sold “As-Is” without any warranty whatsoever including, without limitation, the
Limited Warranty as described herein, notwithstanding anything stated herein to the contrary.

return policy. In case the return policy period has expired and the product is within warranty, the
customer shall submit a claim to D-Link as outlined below:

• The customer must submit with the product as part of the claim a written description of the
Hardware defect or Software nonconformance in sufficient detail to allow D-Link to confirm
the same.

• The original product owner must obtain a Return Material Authorization (“RMA”) number from
the Authorized D-Link Service Office and, if requested, provide written proof of purchase of
the product (such as a copy of the dated purchase invoice for the product) before the

• After an RMA number is issued, the defective product must be packaged securely in the
original or other suitable shipping package to ensure that it will not be damaged in transit, and
the RMA number must be prominently marked on the outside of the package. Do not include any
manuals or accessories in the shipping package. D-Link will only replace the defective portion
of the Product and will not ship back any accessories.

• The customer is responsible for all in-bound shipping charges to D-Link. No Cash on Delivery
(“COD”) is allowed. Products sent COD will either be rejected by D-Link or become the
property of D-Link. Products shall be fully insured by the customer. D-Link will not be held
responsible for any packages that are lost in transit to D-Link. The repaired or replaced
