Channel Width This field is available only when 802.11n/g is selected as the 802.11 Mode.
Select whether the ZyXEL Device uses a wireless channel bandwidth of 20 or 40
MHz. A standard 20MHz channel offers transfer speeds of up to 150Mbps whereas
a 40MHz channel uses two standard channels and offers speeds of up to 300Mbps.
However, not all devices support 40MHz channels. Select 20MHz to use regular
20MHz channels, or select 20/40 MHz to allow the ZyXEL Device to adjust the
channel bandwidth depending on network conditions.
Channel ID Set the operating frequency/channel depending on your particular region.
To manually set the ZyXEL Device to use a channel, select a channel from the drop-
down list box.
Short GI This field is available only when 802.11n/g is selected as the 802.11 Mode. Select
Enable to use the 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.
A-MPDU
Aggregation
This field is available only when 802.11n/g is selected as the 802.11 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.
RTS/CTS
Threshold
The threshold (number of bytes) for enabling RTS/CTS (Request To Send / Clear To
Send) 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 (256) 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 one of the following 100%(Full Power), 50%,
25%, 12.5% or Minimum. See the product specifications for more information on
your ZyXEL Device’s output power.
SSID Profile The SSID (Service Set IDentifier) identifies the Service Set with which a wireless
station is associated. Wireless stations associating to the access point (AP) must
have the same SSID. Select an SSID Profile from the drop-down list box.
Configure SSID profiles in the SSID screen (see
Section 10.2 on page 140 for
information on configuring SSID).
Note: If you are configuring the ZyXEL Device from a computer
connected to the wireless LAN and you change the
ZyXEL Device’s SSID or security 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 ZyXEL Device’s new
settings.

Breathing LED
Select this box to disable the WLAN LED (light). Clear this box to enable the WLAN
LED.
