5.1 Wireless LAN Overview
This section introduces the wireless LAN and some basic configurations. A wireless LAN can be as simple
as two computers with wireless adapters communicating in a peer-to-peer network or as complex as a
number of computers with wireless adapters communicating through access points (APs) which bridge
network traffic to the wired LAN.
5.2 Output Power Management
Output Power Management is the ability to set the level of output power.
There may be interference or difficulty with channel assignment when there is a high density of APs within
a coverage area. In this case you can lower the output power of each access point, thus enabling you to
place access points closer together.

(12.6mW).
5.5 Configuring Roaming
In a network environment with multiple access points, wireless stations are able to switch from one access
point to another as they move between the coverage areas. This is roaming. As the wireless station moves
from place to place, it is responsible for choosing the most appropriate access point depending on the signal
strength, network utilization or other factors.
If the roaming feature is not enabled on the access points, information is not communicated between the
access points when a wireless station moves between coverage areas. The wireless station may not be able
to communicate with other wireless stations on the network and vice versa.
To enable roaming on your ZyAIR, click ADVANCED, WIRELESS and then the Roaming tab. The
screen appears as shown.

or more ZyAIRs on the same subnet.
All APs on the same subnet and the wireless stations must have
the same ESSID to allow roaming.
Port Enter the port number to communicate roaming information between APs. The port
number must be the same on all APs. The default is 16290. Make sure this port is not
used by other services.
5.6 Configuring IEEE 802.1x Authentication
The IEEE 802.1x standard outlines enhanced security methods for both the authentication of wireless
stations and encryption key management. Authentication can be done using the local user database internal
to the ZyAIR (authenticate up to 32 users) or an external RADIUS server for an unlimited number of users.
To change your ZyAIR’s authentication settings, click ADVANCED, WIRELESS and then the 802.1x
tab. The screen appears as shown.

5.7 Local User Database and RADIUS Overview
EAP is an authentication protocol designed originally to run over PPP (Point-to-Point Protocol) frame in
order to support multiple types of user authentication. RADIUS is based on a client-sever model that
supports authentication, authorization and accounting. The access point (ZyAIR) is the client and the server
is the RADIUS server. RADIUS is a simple package exchange in which your ZyAIR acts as a message
relay between the wireless station and the network RADIUS server. In order to ensure network security, the
access point and the RADIUS server use a shared secret key, which is a password, they both know. The key
is not sent over the network. In addition to the shared key, password information exchanged is also
encrypted to protect the network from unauthorized access. By using EAP to interact with an EAPcompatible RADIUS server, the access point helps a wireless station and a RADIUS server to perform
mutual authentication.
To authenticate wireless users without interacting with a network RADIUS server, you can store user
profiles locally. To change your ZyAIR’s local user list, click ADVANCED, WIRELESS and then the
Local User Database tab.
If you do enable the EAP authentication, you need to specify the local user database or the external sever
for remote user authentication. To set up your ZyAIR’s local user database, click ADVANCED,
WIRELESS and then the Local User Database tab. To set up your ZyAIR’s RADIUS server settings,
click WIRELESS, then the RADIUS tab.
