Wireless Basics 

802.1x provides an extra level of security to your wireless network.  Through 

its Authentication protocol (when 802.1x is activated), only clients with 

802.1x authentication will be permitted to communicate in your network; all 

other clients will be denied access.  This is a far more secure wireless 

network than has previously been available.  

All devices on the network must be 802.1x compatible and must share the 

same EAP type.  For Authentication purposes you will need a radius server 

in your network. 

Installation Considerations 

Designed to go up to 1,312 feet (400 meters) outdoors and up to 328 feet 

(100 meters) indoors, the D-Link AirPlus DWL-520+ lets you access your 

network with your computer from virtually anywhere. Keep in mind, however, 

that the number, thickness and location of walls, ceilings or other objects that 

the wireless signal must pass thru may limit range. Typical ranges vary 

depending on the types of materials and any background RF (radio 

frequency) noise in your home or business. The key to maximizing range is 

to follow these basic guidelines: 

1.

Keep the number of walls and ceilings between the wireless Access 

Point and your receiving device (i.e., the DWL-520+) to a minimum - 

Each wall or ceiling can reduce your D-Link AirPlus Wireless product’s 

range from 3-90 feet (1-30 meters.)  Position your Access Points, 

Residential Gateways, and computers so that the number of walls or 

ceilings is minimized. 

2.  Be aware of the direct line between Access Points, Residential 

Gateways (routers), and computers.  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! Try to make 

sure that the Access Points and Adapters are positioned so that the 

signal will travel straight through a wall or ceiling 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, 

and computers with wireless adapters so that the signal passes through 

drywall or open doorways and not other materials. 

4.   Make sure that the device’s antenna is positioned for best reception by 

using the software signal strength tools included with your product.   

5.  Keep your product away (at least 3-6 feet or 1-2 meters) from electrical 

devices or appliances that may generate extreme RF noise.
