DESCRIPTION
Specify the maximum number (from 1 to 64) of the wireless stations that
may connect to the Device.
Set the output power of the Device. If there is a high density of APs in an
area, decrease the output power to reduce interference with other APs.
Select one of the following 20%, 40%, 60%, 80% or 100%.
Select a data rate at which the Device transmits wireless multicast traffic.
If you select a high rate, multicast traffic may occupy all the bandwidth
and cause network congestion.
Select 802.11b Only to allow either IEEE 802.11b or IEEE 802.11g
compliant WLAN devices to associate with the Device. In this mode, all
wireless devices can only transmit at the data rates supported by IEEE
802.11b.
Select 802.11g Only to allow IEEE 802.11g compliant WLAN devices to
associate with the Device. IEEE 802.11b compliant WLAN devices can
associate with the Device only when they use the short preamble type.
Select 802.11n Only to only allow IEEE 802.11n compliant WLAN
devices to associate with the Device. This can increase transmission
rates, although IEEE 802.11b or IEEE 802.11g clients will not be able to
connect to the Device. If you select 802.11 Only, WEP and TKIP
security modes are not supported.
Select 802.11b/g Mixed to allow either IEEE 802.11b or IEEE 802.11g
compliant WLAN devices to associate with the Device. The Device adjusts
the transmission rate automatically according to the wireless standard
supported by the wireless devices.
Select 802.11 b/g/n mixed mode to allow both IEEE802.11b,
IEEE802.11g and IEEE802.11n compliant WLAN devices to associate with
the Device. The transmission rate of your Device might be reduced.
Enabling this feature can help prevent collisions in mixed-mode networks
(networks with both IEEE 802.11b and IEEE 802.11g traffic).
Select Auto to have the wireless devices transmit data after a RTS/CTS
handshake. This helps improve IEEE 802.11g performance.
Select Off to disable 802.11 protection. The transmission rate of your
Device might be reduced in a mixed-mode network.
This field displays Off and is not configurable when you set 802.11
Mode to 802.11b Only.
Select a preamble type from the drop-down list menu. Choices are Long
or Short. The default setting is Long. See the appendix for more
information.
This field is not configurable and the Device uses Short when you set
802.11 Mode to 802.11g Only or 802.11n Only.
Click this to save your changes back to the Device.
