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 LTE3311.
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
LTE3311 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 LTE3311. 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 LTE3311 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 LTE3311. The LTE3311 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
LTE3311. This can increase transmission rates, although IEEE 802.11b or IEEE
802.11g clients will not be able to connect to the LTE3311.
• 802.11gn: allows either IEEE 802.11g or IEEE 802.11n compliant WLAN devices to
associate with the LTE3311. The transmission rate of your LTE3311 might be reduced.
• 802.11bgn: allows IEEE802.11b, IEEE802.11g and IEEE802.11n compliant WLAN
devices to associate with the LTE3311. The transmission rate of your LTE3311 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 Section 7.3 on page 69 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.
Apply Click Apply to save your changes back to the LTE3311.
Cancel Click Cancel to reload the previous configuration for this screen.
