possible encryption method, regardless of your client devices.
* Maximum wireless signal rate derived from IEEE Standard 802.11g, 802.11a and Draft 802.11n specifications. Actual data throughput will vary. Network conditions and
environmental factors, including volume of network traffic, building materials and construction, and network overhead, lower actual data throughput rate. Environmental
conditions will adversely affect wireless signal range.

Section 1 - Product Overview
• Faster Wireless Networking - The DAP-1555 provides up to 300Mbps* wireless connection with other
802.11n wireless clients. This capability allows users to participate in real-time activities online, such as
video streaming, online gaming, and real-time audio. The performance of this 802.11n wireless access
point gives you the freedom of wireless networking at speeds 650% faster than 802.11g.
• Compatible with 802.11a, 802.11b and 802.11g Devices - The DAP-1555 is still fully compatible with
the IEEE 802.11a/b/g standard, so it can connect with existing 802.11a/b/g PCI, USB and Cardbus
adapters.
• Advanced Firewall Features - The Web-based user interface displays advanced network management
features including:
Content Filtering - Easily applied content filtering based on MAC Address.
• User-friendly Setup Wizard - Through its easy-to-use Web-based user interface, the DAP-1555 lets you

Section 2 - Installation
Before you Begin
Installation
This section will walk you through the installation process. Placement of the DAP-1555 is very important. Do not place
the DAP-1555 in an enclosed area such as a closet, cabinet, or in the attic or garage.
Please configure the MediaBridge 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 MediaBridge, then
you must turn off your modem, disconnect the USB cable and connect an Ethernet cable to the Internet port on the
MediaBridge, 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.

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 in not in use.

11D-Link DAP-1555 User Manual
Section 2 - Installation
Depending on how you want to use your DAP-1555 will determine which mode you use on the DAP-1555. This section
will help you figure out which setting works with your setup.
AP Mode
If you already have a wired or wireless router, and want to add a MediaBand (5GHz wireless), to your network, you will
need to move the switch on the back panel of the DAP-1555 to “AP”.
Bridge Mode
If you want to wirelessly connect multiple Ethernet enabled devices such as game consoles, media players, or network
attached storage devices you will need to move the switch on the back panel of the DAP-1555 to “BRIDGE”.

12D-Link DAP-1555 User Manual
Section 2 - Installation
Create a Full MediaBand (5GHz wireless) Network
If you have two DAP-1555 devices and want to create a wireless network with full MediaBand technology you will need
to connect one MediaBridge to your router and move the switch on the back panel to “AP”. The second MediaBridge
will need to be placed next to your Ethernet-enabled devices and you will need to move the switch on the back panel
to “BRIDGE”.
