Introduction
Introduction
The DAP-2553 802.11a/n or b/g/n switchable AP increases productivity by allowing you to work
faster and more efciently. With the DAP-2553, bandwidth-intensive applications like graphics or
multimedia will benet signicantly because large les are now able to move across the network
quickly.
The DAP-2553 is capable of operating in one of four different wireless networking modes; access
point, WDS (Wireless Distribution System) with AP, WDS, or Wireless Client mode.
Use less wiring, enjoy increased flexibility, save time and money with PoE (Power over Ethernet).
With PoE, the DAP-2553 shares power and data over the CAT5 cable, making the setup of your
network less expensive and more convenient.
An ideal solution for quickly creating and extending a wireless local area network (WLAN) in
ofces or other workplaces, trade shows, and special events, the DAP-2553 providing data transfers
rates up to 300Mbps. (The 802.11n standard is backwards compatible with 802.11a, 802.11g,
and 802.11b devices.)
WPA/WPA2 is offered in two flavors: Enterprise (used for corporations) and Personal (used for
home users).
WPA-Personal and WPA2-Personal are directed towards home users who do not have the serverbased equipment required for user authentication. The method of authentication is similar to WEP
because you define a “Pre-Shared Key” on the wireless router/AP. Once the pre-shared key is
conrmed and satised at both the client and access point, access is then granted.The encryption
method used is referred to as the Temporal Key Integrity Protocol (TKIP), which offers per-packet
dynamic hashing. It also includes an integrity checking feature which ensures that the packets
were not tampered with during wireless transmission.
WPA-Enterprise and WPA2-Enterprise are ideal for businesses that already have existing security
infrastructures established. Management and security implementation can now be centralized
on a server participating on the network. Utilizing 802.1x with a RADIUS (Remote Authentication
Dial-in User Service) server, a network administrator can dene a list of authorized users who
can access the wireless LAN. When attempting to access a wireless LAN with WPA-Enterprisee
congured, the new client will be requested to enter a username with a password.. If the new client
is authorized by the administration, and enters the correct username and password, then access is
then granted. In the case where an employee leaves the company, the network administrator is able
to remove the previous employee from the authorized list to avoid compromising the network.
EAP (Extensible Authentication Protocol) is available through the WindowsÂŽ XP operating system.
You will need to use the same type of EAP protocol on all devices in your network when using
the 802.1x feature.

Wireless Basics
Wireless Basics
D-Link wireless products are based on industry standards to provide high-speed wireless
connectivity that is easy to use within your home, business or public access wireless networks.
D-Link wireless products provides you with access to the data you want, whenever and wherever
you want it. Enjoy the freedom that wireless networking can bring to you.
WLAN use is not only increasing in both home and ofce environments, but in public areas as well,
such as airports, coffee shops and universities. Innovative ways to utilize WLAN technology are
allowing people to work and communicate more efciently. Increased mobility and the absence
of cabling and other types of xed infrastructure have proven to be benecial to many users.
Wireless adapter cards used on laptop and desktop systems support the same protocols as
Ethernet adapter cards, allowing wireless users to use the same applications as those used on
a wired network.
People use WLAN technology for many different purposes:
Mobility - productivity increases when people can have access to data in any location within
the operating range of their WLAN. Management decisions based on real-time information can
signicantly improve the efciency of a worker.
Low implementation costs - WLANs are easy to set up, manage, change and relocate. Networks
that frequently change can benet from WLAN's ease of implementation. WLANs can operate in
locations where installation of wiring may be impractical.
Installation and network expansion - by avoiding the complications of troublesome cables,
a WLAN system can be fast and easy during installation, especially since it can eliminate the
need to pull cable through walls and ceilings. Wireless technology provides more versatility by
extending the network beyond the home or ofce.
Inexpensive solution - wireless network devices are as competitively priced as conventional
Ethernet network devices. The DAP-2553 saves money by providing users with multi-functionality
congurable in four different modes.
Scalability - Congurations can be 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
Standards-Based Technology
The DAP-2553 Wireless Access Point utilizes the 802.11a, 802.11b, 802.11g, and 802.11n (draft)
standards.
The IEEE 802.11n (draft) standard is an extension of the 802.11a, 802.11b, and 802.1g standards
that came before it. It increases the maximum wireless signal rate up to 300 Mbps** within both
the 2.4 GHz and the 5 GHz bands, utilizing OFDM technology.
This means that in most environments - within the specied range of this device - you will be able
to transfer large les 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 simultaneously transmitted
at different frequencies to the receiver. OFDM reduces the amount of crosstalk (interference) in
signal transmissions.
The D-Link DAP-2553 will automatically sense the best possible connection speed to ensure the
greatest possible speed and range.
802.11n offers the most advanced network security features available today, including WPA.
*Maximum wireless signal rate derived from IEEE Standard 802.11 specications. Actual data throughput may vary. Network
conditions and environmental factors, including volume of network trafc, building materials and construction, and network overhead
can lower actual data throughout rate.

Wireless Basics
Installation Considerations
The D-Link DAP-2553 lets you access your network, using a wireless connection, from virtually
anywhere within its operating range. 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 DAP-2553 and other network
devices to a minimum - each wall or ceiling can reduce your DAP-2553’s range
by 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
(0.5 meters), at a 45-degree angle appears to be almost 3 feet (1 meter) thick. At
a 2-degree angle, the wall appears to be over 42 feet (14 meters) thick! Position
your devices so that the signal will travel straight through a wall or ceiling - instead
of at an angle - for better reception.
3 Building materials can impede the wireless signal - a solid metal door or aluminum
studs can 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 through other materials.
Keep your product away - at least 3-6 feet or 1-2 meters - from electrical devices
or appliances that generate RF noise.
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 when the
phone is not in use.

Beacon Interval Beacons are packets sent by an access point to synchronize a
(25-500): wireless network. Specify a value in milliseconds. The default (100)
is recommended. Setting a higher beacon interval can help to save
the power of wireless clients, while setting a lower one can help a
wireless client connect to an access point faster.
DTIM Interval Select a Delivery Trafc Indication Message setting between 1 and
(1-15): 15. 1 is the default setting. DTIM is a countdown informing clients of
the next window for listening to broadcast and multicast messages.
Transmit Power: This setting determines the power level of the wireless transmission.
Transmitting power can be adjusted to eliminate overlapping of wireless area coverage between two access points where interference
is a major concern. For example, if wireless coverage is intended for
half of the area, then select 50% as the option. Use the pull-down

Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of
the DAP-2553 Wireless Access Point.We will cover various aspects of the network setup, especially
the network adapters. Please read the following if you are having any technical difculties.
Note: It is recommended that you use an Ethernet connection to congure the DAP-2553.
1. The computer used to congure the DAP-2553 cannot access the Conguration menu.
„ Check if the LAN LED on the DAP-2553 is ON. If the LED is not ON, check if the cable for
the Ethernet connection is securely inserted.
„ Check if the Ethernet adapter is working properly. Please see item 3 of this Troubleshooting
section to check that the drivers for the network adapters are loaded properly.
„ Check if the IP address is in the same range and subnet as the DAP-2553.
Note: The default IP address of the DAP-2553 is 192.168.0.50. 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 DAP-2553 is responding. Go to Start>Run>Type
Command>Type ping 192.168.0.50. 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 DAP-2553.

Troubleshooting
2. The wireless client cannot access the Internet within Infrastructure mode.
Make sure the wireless client is associated and joined with the correct access point. To check
this connection, right-click on the Local Area Connection icon in the taskbar and 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 same IP address range
as the access point and gateway. Since the DAP-2553 has an IP address of 192.168.0.50,
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; there may be no two devices with 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 the Local Area Connection icon in
the taskbar, then select the Support tab and the IP address will be displayed.
„If it is necessary to assign a Static IP Address to the wireless adapter. 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.

Troubleshooting
3. 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 its wireless range.
4. Why does my wireless connection keep dropping?
„Antenna Orientation - try different antenna orientations for the DAP-2553. Try to keep the
antenna at least 6 inches away from the wall or other objects.
„If you are using 2.4 GHz cordless phones, X-10 equipment or other home security systems,
ceiling fans, or lights, your wireless connection will degrade dramatically or even drop. Try
changing the channel of 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 generate RF noise
like microwaves, monitors, electric motors, etc.
5. Why can’t I get a wireless connection?
If you have enabled encryption on the DAP-2553, you must also enable encryption on all wireless
clients in order to establish a wireless connection.
„Make sure that the SSID on the AP and the wireless client are exactly the same. If they are
not, wireless connection cannot be established.
„Move the DAP-2553 and the wireless client into the same room and then test the wireless
connection.
„Disable all security settings.
„Turn off your DAP-2553 and the client. Turn the DAP-2553 back on again, and then turn on
the client.
„Make sure that all devices are set to Infrastructure mode.
„Check that the LED indicators are indicating normal activity. If not, check that the AC power
and Ethernet cables are rmly connected.
„Check that the IP address, subnet mask, gateway, and DNS settings are correctly entered
for the network.
„If you are using 2.4 GHz cordless phones, X-10 equipment, or other home security systems,
ceiling fans, or lights, your wireless connection will degrade dramatically or drop altogether.
Try changing the channel on your DAP-2553, and on all the devices in your network to avoid
interference.
„Keep your product away - at least 3-6 feet - from electrical devices that generate RF noise
like microwaves, monitors, electric motors, etc.
