Passphrase
Type If you set security for the wireless LAN and have the ZyXEL Device
generate a password, the setting in this field determines how the ZyXEL
Device generates the password.
Select None to set the ZyXEL Device’s password generation to not be
based on a passphrase.
Select Fixed to use a 16 character passphrase for generating a password.
Select Variable to use a 16 to 63 character passphrase for generating a
password.
Passphrase
Key For a fixed type passphrase enter 16 alphanumeric characters (0-9, A-Z,
with no spaces). It must contain both letters and numbers and is case-
sensitive.
For a variable type passphrase enter 16 to 63 alphanumeric characters (0-
9, A-Z, with no spaces). It must contain both letters and numbers and is
case-sensitive.
Bandwidth Select whether the ZyXEL Device uses a wireless channel width of 20MHz
or 40MHz .
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 300 Mbps.
40MHz (channel bonding or dual channel) bonds two adjacent radio
channels to increase throughput. The wireless clients must also support 40
MHz. It is often better to use the 20 MHz setting in a location where the
environment hinders the wireless signal.
Select 20MHz if you want to lessen radio interference with other wireless
devices in your neighborhood or the wireless clients do not support
channel bonding.
Control
Sideband This is available for some regions when you select a specific channel and
set the Bandwidth field to
40MHz . Set whether the control channel (set in
the Channel field) should be in the Lower or Upper range of channel
bands.
Wireless Network Settings
Wireless
Network
Name (SSID)
The SSID (Service Set IDentity) identifies the service set with which a
wireless device is associated. Wireless devices associating to the access
point (AP) must have the same SSID.
Enter a descriptive name (up to 32 English keyboard characters) for the
wireless LAN.
Hide SSID Select this check box to hide the SSID in the outgoing beacon frame so a
station cannot obtain the SSID through scanning using a site survey tool.
Client
Isolation Select this to keep the wireless clients in this SSID from communicating
with each other through the ZyXEL Device.
