DESCRIPTION
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.
The preceding "0x" is entered automatically. You must configure all four keys, but
only one key can be activated at any one time. The default key is key 1.
Intra-BSS traffic is traffic between wireless stations in the same BSS.
Enable Intra-BSS traffic to allow wireless stations connected to the ZyAIR to
communicate with each other.
Disable Intra-BSS traffic to only allow wireless stations to communicate with the
wired network, not with each other.
(R)STP detects and breaks network loops and provides backup links between
switches, bridges or routers. It allows a bridge to interact with other (R)STP -
compliant bridges in your network to ensure that only one path exists between any
two stations on the network. Select the check box to activate STP on the ZyAIR.
Set the output power of the ZyAIR in this field. If there is a high density of APs within
an area, decrease the output power of the ZyAIR to reduce interference with other
APs. The options are 17dBm (50mW), 15dBm (32mW), 13dBm (20mW) or 11dBm
(12.6mW).
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.
Select Dynamic to have the ZyAIR automatically use short preamble when all
wireless clients support it, otherwise the ZyAIR uses long preamble.
Note: The ZyAIR and the wireless stations MUST use the same
preamble mode in order to communicate.
Select 802.11b Only to allow only IEEE 802.11b compliant WLAN devices to
associate with the ZyAIR.
Select 802.11g Only to allow only IEEE 802.11g compliant WLAN devices to
associate with the ZyAIR.
Select Mixed to allow either IEEE 802.11b or IEEE 802.11g compliant WLAN
devices to associate with the ZyAIR. The transmission rate of your ZyAIR might be
reduced.
Enable Maximum Frame Burst to help eliminate collisions in mixed-mode networks
(networks with both IEEE 802.11g and IEEE 802.11b traffic) and enhance the
performance of both pure IEEE 802.11g and mixed IEEE 802.11b/g networks.
Maximum Frame Burst sets the maximum time, in microseconds, that the ZyAIR
transmits IEEE 802.11g wireless traffic only.
Type the maximum frame burst between 0 and 1800 (650, 1000 or 1800
recommended). Enter 0 to disable this feature.
