DESCRIPTIONS
This field is configurable only when you select Enable WDS Security.
Select TKIP to enable Temporal Key Integrity Protocol (TKIP) security on your WDS.
This option is compatible with other ZyXEL access points that support WDS security.
Use this if the other access points on your network support WDS security but do not
have an AES option.
Note: Check your other AP's documentation to make sure it supports WDS security.
Select AES to enable Advanced Encryption System (AES) security on your WDS. AES
provides superior security to TKIP. Use AES if the other access points on your
network support it for the WDS.
Type a pre-shared key (PSK) from 8 to 63 case-sensitive ASCII characters (including
spaces and symbols). You must also set the peer device to use the same pre-shared
key.
Set the output power of the NWA in this field. If there is a high density of APs in an
area, decrease the output power of the NWA to reduce interference with other APs.
Select one of the following Full (Full Power), 50%, 25%, 12.5% or Min (Minimum).
See the product specifications for more information on your NWA's output power.
Select Dynamic to have the AP automatically use short preamble when wireless
adapters support it, otherwise the AP uses long preamble.
Select Long if you are unsure what preamble mode the wireless adapters support, and
to provide more reliable communications in busy wireless networks.
(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 its smallest value (1)
turns on the RTS/CTS handshake.
The threshold (number of bytes) for the fragmentation boundary for directed
messages. It is the maximum data fragment size that can be sent.
This field is available only when 802.11 b/g/n is selected as the Wireless Mode.
Select Enable to allow the grouping of several A-MSDUs (Aggregate MAC Service Data
Units) into one large A-MPDU (Aggregate MAC Protocol Data Unit). This function allows
faster data transfer rates.
This field is available only when 802.11 b/g/n is selected as the Wireless Mode.
Select Enable to use Short GI (Guard Interval). The guard interval is the gap
introduced between data transmission from users in order to reduce interference.
Reducing the GI increases data transfer rates but also increases interference.
Increasing the GI reduces data transfer rates but also reduces interference.
This section controls the data rates permitted for clients.
For each Rate, select an option from the Configuration list. The options are:
• Basic (1~11 Mbps only): Clients can always connect to the access point at this
speed.
• Optional: Clients can connect to the access point at this speed, when permitted to
do so by the AP.
• Disable: Clients cannot connect to the access point at this speed.
