Section 1 - Product Overview

Introduction

The DAP-2553 802.11n selectable AP increases productivity by allowing you to work faster and more eciently. With the DAP2553, 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 dierent wireless networking modes: access point, WDS (Wireless Distribution System) with AP, WDS, or Wireless Client mode.

Use less wiring, enjoy increased exibility, 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 oces or other workplaces, trade shows, and special events, the DAP-2553 provides data transfer rates up to 450Mbps. (The 802.11n standard is backwards compatible with 802.11a, 802.11g, and 802.11b devices.)

WPA/WPA2 is oered in two options: 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. This method of authentication is similar to WEP because you dene 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 oers 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.

Section 1 - Product Overview

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-Enterprise 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 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.

*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 trac, building materials and construction, and network overhead can lower actual data throughout rate.

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 oce environments, but in public areas as well, such as airports, coee shops and universities. Innovative ways to utilize WLAN technology are allowing people to work and communicate more e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 dierent 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 e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 o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 dierent 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.

Section 2 - Installation

Standards-Based Technology

The DAP-2553 Wireless Access Point utilizes the 802.11a, 802.11b, 802.11g, and 802.11n standards.

The IEEE 802.11n standard is an extension of the 802.11a, 802.11b, and 802.11g standards that came before it. It increases the maximum wireless signal rate up to 450Mbps* within both the 2.4GHz and the 5GHz 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 dierent 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.

IEEE 802.11n oers the most advanced network security features available today, including WPA.

Wireless Installation Considerations

The D-Link AirPremier N wireless access point 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 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 access point and other network devices to a minimum. Each wall or ceiling can reduce your adapter’s range from 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 (.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! Position devices so that the signal will travel straight through a wall or ceiling (instead of at an angle) for better reception.

3. Building Materials make a dierence. A solid metal door or aluminum studs may have a negative eect on the range. Try to position access points, wireless routers, and computers so that the signal passes through drywall or open doorways. Materials and objects such as glass, steel, metal, walls with insulation, water (sh tanks), mirrors, le cabinets, brick, and concrete will degrade your wireless signal.

4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF noise.

5. If you are using 2.4GHz 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 2.4GHz phone base is as far away from your wireless devices as possible. The base transmits a signal even if the phone in not in use.

Beacons are packets sent by an access point to synchronize a 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.

Select a Delivery Trac Indication Message setting between 1 and 15. The default value is 1. DTIM is a countdown informing clients of the next window for listening to broadcast and multicast messages.

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 drop-down menu to select 100%, 50%, 25%, or 12.5%.

WMM stands for Wi-Fi Multimedia. Enabling this feature will improve the user experience for audio and video applications over a Wi-Fi network.

To eectively optimize throughput over long distance links, enter a value for Acknowledgement Time Out between 25 and 200 microseconds for 5 GHz or from 48 to 200 microseconds in the 2.4 GHz in the eld provided.

Troubleshooting

This chapter provides solutions to problems that can occur during the installation and operation of the DAP-2553. Read the following descriptions if you are having problems. (The examples below are illustrated in Windows® XP. If you have a dierent operating system, the screenshots on your computer will look similar to the following examples.)

Why can’t I access the web-based conguration utility?

When entering the IP address of the D-Link access point (192.168.0.50 for example), you are not connecting to a website on the Internet or have to be connected to the Internet. The device has the utility built-in to a ROM chip in the device itself. Your computer must be on the same IP subnet to connect to the web-based utility.

• Make sure you have an updated Java-enabled web browser. We recommend the following:

• Internet Explorer 7.0 or higher, Chrome, Firefox, or Safari 4 or higher

• Verify physical connectivity by checking for solid link lights on the device. If you do not get a solid link light, try using a dierent cable or connect to a dierent port on the device if possible. If the computer is turned o, the link light may not be on.

• Disable any internet security software running on the computer. Software rewalls such as Zone Alarm, Black Ice, Sygate, Norton Personal Firewall, and Windows® rewall may block access to the conguration pages. Check the help les included with your rewall software for more information on disabling or conguring it.

• Congure your Internet settings:

Go to Start > Settings > Control Panel. Double-click the Internet Options Icon. From the Security tab, click the button to restore the settings to their defaults. Click the Connection tab and set the dial-up option to Never Dial a Connection. Click the LAN Settings button. Make sure nothing is checked. Click OK. Go to the Advanced tab and click the button to restore these settings to their defaults. Click OK three times. Close your web browser (if open) and open it.

• Access the web management. Open your web browser and enter the IP address of your D-Link access point in the address bar. This should open the login page for your the web management.

• If you still cannot access the conguration, unplug the power to the access point for 10 seconds and plug back in. Wait about 30 seconds and try accessing the conguration. If you have multiple computers, try connecting using a dierent computer.

What can I do if I forgot my password?

If you forgot your password, you must reset your access point. Unfortunately, this process will change all your settings back to the factory defaults.

To reset the access point, locate the reset button (hole) on the rear panel of the unit. With the access point powered on, use a paperclip to hold the button down for 10 seconds. Release the button and the access point will go through its reboot process. Wait about 30 seconds to access the access point. The default IP address is 192.168.0.50. When logging in, the username is admin and leave the password box empty.

Section 6 - Troubleshooting

How to check your IP address?

After you install your network adapter, by default, the TCP/IP settings should be set to obtain an IP address from a DHCP server (i.e. wireless router) automatically. To verify your IP address, please follow the steps below.

Click on Start > Run. In the run box type cmd and click OK.

At the prompt, type ipcong and press Enter.

This will display the IP address, subnet mask, and the default gateway of your adapter.

If the address is 0.0.0.0, check your adapter installation, security settings, and the settings on your router. Some rewall software programs may block a DHCP request on newly installed adapters.

If you are connecting to a wireless network at a hotspot (e.g. hotel, coee shop, airport), please contact an employee or administrator to verify their wireless network settings.

Section 6 - Troubleshooting

How to statically assign an IP address?

If you are not using a DHCP capable gateway/router, or you need to assign a static IP address, please follow the steps below: Step 1: Windows® 2000: Click on Start > Settings > Control Panel > Network Connections Windows XP: Click on Start > Control Panel > Network Connections Windows Vista®: Click on Start > Control Panel > Network and Internet > Network and Sharing Center > Manage network connections

Step 2: Right-click on the Local Area Connection which represents your network adapter and select Properties.

Step 3: Highlight Internet Protocol (TCP/IP) and click Properties.

Step 4: Click Use the following IP address and enter an IP address that is on the same subnet as your network or the LAN IP address on your router. Example: If the router’s LAN IP address is 192.168.0.1, make your IP address 192.168.0.X where X is a number between 2 and 99. Make sure that the number you choose is not in use on the network. Set Default Gateway the same as the LAN IP address of your router (192.168.0.1). Set Primary DNS the same as the LAN IP address of your router (192.168.0.1). The Secondary DNS is not needed or you may enter a DNS server from your ISP.

Step 5: Click OK twice to save your settings.
