D-Link DWL-520 manual Installation Considerations

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.
