LABEL DESCRIPTION
RTS /CTS
Threshold
(Request To Send) The threshold (number of bytes) for enabling RTS/CTS handshake. Data with
its frame size larger than this value will perform the RTS/CTS handshake. Setting this attribute to
be larger than the maximum MSDU (MAC service data unit) size turns off the RTS/CTS
handshake. Setting this attribute to zero turns on the RTS/CTS handshake. Enter a value between
0 and 2432.
Fragmentation
Threshold
The threshold (number of bytes) for the fragmentation boundary for directed messages. It is the
maximum data fragment size that can be sent. Enter a value between 256 and 2432.
WEP
Encryption
WEP (Wired Equivalent Privacy) encrypts data frames before transmitting them over the wireless
network.
Select Disable to allow wireless stations to communicate with the access points without any data
encryption.
Select 64-bit WEP or 128-bit WEP to enable data encryption.
Authentication
Method
Select Auto, Open System or Shared Key from the drop-down list box.
Key 1 to Key 4 If you chose 64-bit WEP in the WEP Encryption field, then enter any 5 characters (ASCII string)
or 10 hexadecimal characters ("0-9", "A-F") preceded by 0x for each key.
If you chose 128-bit WEP in the WEP Encryption field, then enter 13 characters (ASCII string) or
26 hexadecimal characters ("0-9", "A-F") preceded by 0x for each key.
There are four data encryption keys to secure your data from eavesdropping by unauthorized
wireless users. The values for the keys must be set up exactly the same on the access points as
they are on the wireless stations.
Enable
Breathing LED
Select this check box to enable the Breathing LED, also known as the ZyAIR LED.
The blue ZyAIR LED is on (dimmed) when the ZyAIR is on and blinks brightly (or breaths) when
data is being transmitted to/from its wireless stations. Clear the check box to turn this LED off even
when the ZyAIR is on and data is being transmitted/received.
Apply Click Apply to save your changes back to the ZyAIR.

5.3 Configuring Roaming
A wireless station is a computer with an IEEE 802.11g-compliant wireless adapter. An Access Point (AP)
acts as a bridge between the wireless and wired networks. An AP creates its own wireless coverage area. A
wireless station can associate with a particular access point only if it is within the access point’s coverage
area.
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.
