97
RTS/CTS Threshold 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 256 and 2346.
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 an
even number between 256 and 2346.
Output Power Set the output power of the ZyXEL Device in this field. If there is a high density
of APs in an area, decrease the output power of the ZyXEL Device to reduce
interference with other APs. Select from 100%, 50%, 25%, 12.5% and
Minimum. See the product specifications for more information on your ZyXEL
Device’s output power.
This field is not available when you select 802.11a in the 802.11 Mode field.
Enable WDS Security Select this to turn on security for the ZyXEL Device’s Wireless Distribution
System (WDS). A Wireless Distribution System is a wireless connection
between two or more APs. If you do not select the check box, traffic between
APs is not encrypted.
Note: WDS security is independent of the security settings
between the ZyXEL Device and any wireless clients.
When you enable WDS security, also do the following:
• Select the type of security you want to use (TKIP or AES) to secure traffic
on your WDS.
• Enter a pre-shared key in the PSK field for each access point in your WDS.
Each access point can use a different pre-shared key.
• Configure WDS security and the relevant PSK in each of your other access
point(s).
Note: Other APs must use the same encryption method to
enable WDS security.
TKIP (ZyAIR Series
Compatible)
Select this to enable Temporal Key Integrity Protocol (TKIP) security on your
WDS. This option is compatible with other ZyXEL access points including 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.
Note: At the time of writing, this option is compatible with other
ZyXEL NWA Series and G-3000/G-3000H access points
only.
AES Select this 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.
Note: At the time of writing, this option is compatible with other
ZyXEL NWA Series access points only.
Index This is the index number of the bridge connection.
Active Select the check box to enable the bridge connection. Otherwise, clear the
check box to disable it.
