DAP- 2533 User’s Manual
D-Link AirPremier N Dual Band PoE Access Point
The DAP-2553 802.11a/n or b/g/n switchable AP increases productivity by allowing you to work
faster and more efficiently. With the DAP-2553, bandwidth-intensive applications like graphics or
multimedia will benefit significantly because large files 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
offices 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 server-
based 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
confirmed and satisfied 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 define a list of authorized users who
can access the wireless LAN. When attempting to access a wireless LAN with WPA-Enterprisee
configured, 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 Windows
®
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.
