7.3 Wireless Security
The screen varies depending on what you select in the
Security Mode
field.
7.3.1 No Security
Select
No Security
to allow wireless clients to communicate with the access points without any data
encryption.
Channel Width
Select the wireless channel width used by Zyxel Device.
A standard 20MHz channel offers transfer speeds of up to 144Mbps (2.4GHz) whereas a 40MHz
channel uses two standard channels and offers speeds of up to 300Mbps (2.4GHz).
Because not all devices support 40 MHz channels, select
Auto 20/40MHz
to allow the Zyxel
Device to adjust the channel bandwidth automatically.
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.
802.11 Mode
You can select from the following:
•
802.11b
: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to associate
with the Zyxel Device. In this mode, all wireless devices can only transmit at the data rates
supported by IEEE 802.11b.
•
802.11g
: allows IEEE 802.11g compliant WLAN devices to associate with the Device. IEEE
802.11b compliant WLAN devices can associate with the Zyxel Device only when they use
the short preamble type.
•
802.11bg
: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to associate
with the Zyxel Device. The Zyxel Device adjusts the transmission rate automatically
according to the wireless standard supported by the wireless devices.
•
802.11n
: allows IEEE 802.11n compliant WLAN devices to associate with the Zyxel Device.
This can increase transmission rates, although IEEE 802.11b or IEEE 802.11g clients will not
be able to connect to the Zyxel Device.
•
802.11gn
: allows either IEEE 802.11g or IEEE 802.11n compliant WLAN devices to associate
with the Zyxel Device. The transmission rate of your Zyxel Device might be reduced.
•
802.11bgn
: allows IEEE802.11b, IEEE802.11g and IEEE802.11n compliant WLAN devices to
associate with the Zyxel Device. The transmission rate of your Zyxel Device might be
reduced.
Security Mode
Select
Static WEP
,
WPA-PSK
,
WPA
,
WPA2-PSK
or
WPA2
to add security on this wireless network.
The wireless clients which want to associate to this network must have same wireless security
settings as this device. After you select to use a security, additional options appears in this
screen. See
for detailed information on different security modes. Or
you can select
No Security
to allow any client to associate this network without
authentication.
Note: If the WPS function is enabled (default), only
No Security
and
WPA2-PSK
are
available in this field.
