LABEL DESCRIPTION
ESSID (Extended Service Set IDentity) The ESSID identifies the Service Set with to which a
wireless station is associated. Wireless stations associating to the access point (AP)
must have the same ESSID. Enter a descriptive name (up to 32 printable 7-bit ASCII
characters) for the wireless LAN.
If you are configuring the ZyAIR from a computer connected to
the wireless LAN and you change the ZyAIR’s ESSID or WEP
settings, you will lose your wireless connection when you
press Apply to confirm. You must then change the wireless
settings of your computer to match the ZyAIR’s new settings.
Hide ESSID Select this check box to hide the ESSID in the outgoing beacon frame so a station
cannot obtain the ESSID through passive scanning using a site survey tool.
Choose
Channel ID Set the operating frequency/channel depending on your particular region.
RTS/CTS
Threshold RTS/CTS handshake avoids retransmitting due to hidden nodes. Enter a value
between
0 and 2432 . The default is 2432 .
Fragmentation
Threshold Fragmentation threshold defines the maximum data fragment size that can be sent.
Enter a value between
256 and 2432 .

5.4 Configuring Roaming
A wireless station is a device with an IEEE 802.11b or 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.
The roaming feature on the access points allows the access points to relay information about the wireless
stations to each other. When a wireless station moves from a coverage area to another, it scans and uses the
