Select No Security to allow wireless clients to communicate with the access points without any
data encryption.
PLA4231 User's Guide
DESCRIPTION
This displays the channel the PLA4231 is currently using.
Select the wireless channel width used by PLA4231.
A standard 20 MHz channel offers transfer speeds of up to 150Mbps whereas a 40 MHz
channel uses two standard channels and offers speeds of up to 300 Mbps.
Because not all devices support 40 MHz channels, select Auto 20/40 MHz to allow the
PLA4231 to adjust the channel bandwidth automatically.
40 MHz (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 20 MHz if you want to lessen radio interference with other wireless devices in your
neighborhood or the wireless clients do not support channel bonding.
You can select from the following:
• 802.11b: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to
associate with the PLA4231. 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 PLA4231 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 PLA4231. The PLA4231 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
PLA4231. This can increase transmission rates, although IEEE 802.11b or IEEE
802.11g clients will not be able to connect to the PLA4231. I
• 802.11gn: allows either IEEE 802.11g or IEEE 802.11n compliant WLAN devices to
associate with the PLA4231. The transmission rate of your PLA4231 might be
reduced.
• 802.11 bgn: allows IEEE802.11b, IEEE802.11g and IEEE802.11n compliant WLAN
devices to associate with the PLA4231. The transmission rate of your PLA4231 might
be reduced.
Select Static WEP, WPA-PSK, or WPA2-PSK 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
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.
