Section 2 - Installation
Installation
This section will walk you through the installation process. Placement of the DAP-1525 is very important. Do not place the
DAP-1525 in an enclosed area such as a closet, cabinet, or in the attic or garage.
Before you Begin
Please configure the Wireless Bridge with the computer that was last connected directly to your modem. Also, you can only
use the Ethernet port on your modem. If you were using the USB connection before using the Wireless Bridge, then you must
turn off your modem, disconnect the USB cable and connect an Ethernet cable to the Internet port on the Wireless Bridge, and
then turn the modem back on. In some cases, you may need to call your ISP to change connection types (USB to Ethernet).
If you have DSL and are connecting via PPPoE, make sure you disable or uninstall any PPPoE software such as WinPoet, Broadjump,
or Enternet 300 from your computer or you will not be able to connect to the Internet.

Section 2 - Installation
Wireless Installation Considerations
The D-Link 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 D-Link 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 difference. A solid metal door or aluminum studs may have a negative effect on
range. Try to position access points, wireless access points, and computers so that the signal passes through
drywall or open doorways. Materials and objects such as glass, steel, metal, walls with insulation, water (fish
tanks), mirrors, file 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 is not
in use.

Section 4 - Security
Wireless Security
This section will show you the different levels of security you can use to protect your data from intruders. The
DAP-1525 offers the following types of security:
• WEP (Wireless Security Basic)
• WPA (Wi-Fi Protected Access)
• WPA2(Wireless Security enhanced)
What is WPA?
WPA, or Wi-Fi Protected Access, is a Wi-Fi standard that was designed to improve the security features of WEP (Wired Equivalent
Privacy).
The 2 major improvements over WEP:
• Improved data encryption through the Temporal Key Integrity Protocol (TKIP). TKIP scrambles the keys using a
hashing algorithm and, by adding an integrity-checking feature, ensures that the keys haven’t been tampered
with. WPA2 is based on 802.11i and uses Advanced Encryption Standard (AES) instead of TKIP.
• User authentication, which is generally missing in WEP, through the extensible authentication protocol (EAP).
WEP regulates access to a wireless network based on a computer’s hardware-specific MAC address, which is
relatively simple to be sniffed out and stolen. EAP is built on a more secure public-key encryption system to
ensure that only authorized network users can access the network.
WPA-PSK/WPA2-PSK uses a passphrase or key to authenticate your wireless connection. The key is an alpha-numeric password
between 8 and 63 characters long. The password can include symbols (!?*&_) and spaces. This key must be the exact same key
entered on your wireless bridge or access point.
WPA/WPA2 incorporates user authentication through the Extensible Authentication Protocol (EAP). EAP is built on a more
secure public key encryption system to ensure that only authorized network users can access the network.

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:
- Microsoft Internet Explorer 6.0 and higher
- Mozilla Firefox 3.0 and higher
- Google Chrome 2.0 and higher
- Apple Safari 3.0 and 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 different
cable or connect to a different port on the device if possible. If the computer is turned off, the link light may not be on.
• Disable any internet security software running on the computer. Software firewalls such as Zone Alarm, Black Ice, Sygate,
Norton Personal Firewall, and Windows® XP firewall may block access to the configuration pages. Check the help files included
with your firewall software for more information on disabling or configuring it.

• Configure 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 configuration, unplug the power to the access point for 10 seconds and plug back in. Wait about
30 seconds and try accessing the configuration. If you have multiple computers, try connecting using a different computer.
2. 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.

3.Why can’t I connect to certain sites or send and receive emails when connecting through my access point?
If you are having a problem sending or receiving email, or connecting to secure sites such as eBay, banking sites, and Hotmail,
we suggest lowering the MTU in increments of ten (Ex. 1492, 1482, 1472, etc).
Note: AOL DSL+ users must use MTU of 1400.
To find the proper MTU Size, you’ll have to do a special ping of the destination you’re trying to go to. A destination could be
another computer, or a URL.
• Click on Start and then click Run.
• Windows® 95, 98, and Me users type in command (Windows® NT, 2000, and XP users type in cmd) and click Enter
(or click OK).
• Once the window opens, you’ll need to do a special ping. Use the following syntax:
ping [url] [-f ] [-l] [MTU value]
Example: ping yahoo.com -f -l 1472
You should start at 1472 and work your way down by 10 each time.

Once you get a reply, go up by 2 until you get a fragmented packet. Take that value and add 28 to the value to account for the
various TCP/IP headers. For example, lets say that 1452 was the proper value, the actual MTU size would be 1480, which is the
optimum for the network we’re working with (1452+28=1480).
Once you find your MTU, you can now configure your access point with the proper MTU size.
To change the MTU rate on your access point follow the steps below:
• Open your browser, enter the IP address of your access point (192.168.0.50) and click OK.
• Enter your username (admin) and password (blank by default). Click OK to enter the web configuration page
for the device.
• Click on Setup and then click Manual Configure.
• To change the MTU enter the number in the MTU field and click Save Settings to save your settings.
• Test your email. If changing the MTU does not resolve the problem, continue changing the MTU in increments
of ten.

Wireless Basics
D-Link 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
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 Access point is a device used to
provide this link.

What is Wireless?
Wireless or Wi-Fi technology is another way of connecting your computer to the network without using wires. Wi-Fi uses radio
frequency to connect wirelessly, so you have the freedom to connect computers anywhere in your home or office.
D-Link is the worldwide leader and award winning designer, developer, and manufacturer of networking products. D-Link
delivers the performance you need at a price you can afford. D-Link has all the products you need to build your network.
How does wireless work?
Wireless works similar to how cordless phone work, through radio signals to transmit data from one point A to point B. But
wireless technology has restrictions as to how you can access the network. You must be within the wireless network range area
to be able to connect your computer. There are two different types of wireless networks Wireless Local Area Network (WLAN),
and Wireless Personal Area Network (WPAN).
Wireless Local Area Network (WLAN)
In a wireless local area network, a device called an Access Point (AP) connects computers to the network. The access point has
a small antenna attached to it, which allows it to transmit data back and forth over radio signals. With an indoor access point
as seen in the picture, the signal can travel up to 300 feet. With an outdoor access point the signal can reach out up to 30 miles
to serve places like manufacturing plants, industrial locations, college and high school campuses, airports, golf courses, and
many other outdoor venues.

Wireless Personal Area Network (WPAN)
Bluetooth is the industry standard wireless technology used for WPAN. Bluetooth devices in WPAN operate in a range up to
30 feet away.
Compared to WLAN the speed and wireless operation range are both less than WLAN, but in return it doesn’t use nearly as
much power which makes it ideal for personal devices, such as mobile phones, PDAs, headphones, laptops, speakers, and other
devices that operate on batteries.
Who uses wireless?
Wireless technology as become so popular in recent years that almost everyone is using it, whether it’s for home, office, business,
D-Link has a wireless solution for it.
Home
• Gives everyone at home broadband access
• Surf the web, check email, instant message, etc.
• Gets rid of the cables around the house
• Simple and easy to use
Small Office and Home Office
• Stay on top of everything at home as you would at office
• Remotely access your office network from home
• Share Internet connection and printer with multiple computers
• No need to dedicate office space

Where is wireless used?
Wireless technology is expanding everywhere not just at home or office. People like the freedom of mobility and it’s becoming
so popular that more and more public facilities now provide wireless access to attract people. The wireless connection in public
places is usually called “hotspots”.
Using a D-Link Cardbus Adapter with your laptop, you can access the hotspot to connect to Internet from remote locations
like: Airports, Hotels, Coffee Shops, Libraries, Restaurants, and Convention Centers.
Wireless network is easy to setup, but if you’re installing it for the first time it could be quite a task not knowing where to start.
That’s why we’ve put together a few setup steps and tips to help you through the process of setting up a wireless network.
Tips
Here are a few things to keep in mind, when you install a wireless network.
Centralize your access point or Access Point
Make sure you place the bridge/access point in a centralized location within your network for the best performance. Try to
place the bridge/access point as high as possible in the room, so the signal gets dispersed throughout your home. If you have
a two-story home, you may need a repeater to boost the signal to extend the range.
Eliminate Interference
Place home appliances such as cordless telephones, microwaves, wireless speakers, and televisions as far away as possible from
the bridge/access point. This would significantly reduce any interference that the appliances might cause since they operate
on same frequency.

Appendix A - Wireless Basics
Security
Don’t let your next-door neighbors or intruders connect to your wireless network. Secure your wireless network by turning on
the WPA or WEP security feature on the access point. Refer to product manual for detail information on how to set it up.
Wireless Modes
There are basically two modes of networking:
•Infrastructure – All wireless clients will connect to an access point or wireless bridge.
•Ad-Hoc – Directly connecting to another computer, for peer-to-peer communication, using wireless network
adapters on each computer, such as two or more wireless network Cardbus adapters.
An Infrastructure network contains an Access Point or wireless bridge. All the wireless devices, or clients, will connect to the
wireless bridge or access point.
An Ad-Hoc network contains only clients, such as laptops with wireless cardbus adapters. All the adapters must be in Ad-Hoc
mode to communicate.

Check your IP address
After you install your new D-Link 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. (Windows® 7/Vista® users type cmd in the Start Search box.)
At the prompt, type ipconfig 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 access point.
Some firewall 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, coffee shop, airport), please contact an
employee or administrator to verify their wireless
network settings.
