P-2812HNU-51c User's Guide
DESCRIPTION
Select 802.11b Only to only allow IEEE 802.11b compliant WLAN
devices to associate with the P-2812HNU-51c.
Select 802.11g Only to allow IEEE 802.11g compliant WLAN devices to
associate with the P-2812HNU-51c. IEEE 802.11b compliant WLAN
devices can associate with the P-2812HNU-51c only when they use the
short premble type.
Select 802.11n Only to only allow IEEE 802.11n compliant WLAN
devices to associate with the P-2812HNU-51c. This can increase
transmission rates, although IEEE 802.11b or IEEE 802.11g clients will
not be able to connect to the P-2812HNU-51c.
Select 802.11b/g Mixed to allow either IEEE 802.11b or IEEE 802.11g
compliant WLAN devices to associate with the P-2812HNU-51c. The P-
2812HNU-51c 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 P-2812HNU-51c. The transmission rate of your P-2812HNU-51c
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 P-
2812HNU-51c 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 P-2812HNU-51c 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 P-2812HNU-51c.
