to Associate:
Use this field to set a maximum number of wireless stations that may connect to the G-
560.
Enter the number (from 1 to 32) of wireless stations allowed.
Output Power
Management
Set the output power of the G-560 in this field. If there is a high density of APs within an
area, decrease the output power of the G-560 to reduce interference with other APs.
The options are Full, 50%, 25% and 12%.
Preamble Type Preamble is used to signal that data is coming to the receiver.
Short preamble increases performance as less time sending preamble means more
time for sending data. All IEEE 802.11b compliant wireless adapters support long
preamble, but not all support short preamble.
Select Long preamble if you are unsure what preamble mode the wireless adapters
support, and to provide more reliable communications in busy wireless networks. Select
Short preamble if you are sure the wireless adapters support it, and to provide more
efficient communications.
The G-560 and the wireless stations MUST use the same
preamble mode in order to communicate.

6.4 Wireless Security Overview
Wireless security is vital to your network to protect wireless communication between wireless stations,
access points and the wired network.
The figure below shows the possible wireless security levels on your G-560. EAP (Extensible Authentication
Protocol) is used for authentication and utilizes dynamic WEP key exchange. It requires interaction with a
RADIUS (Remote Authentication Dial-In User Service) server either on the WAN or your LAN to provide
authentication service for wireless stations.
