DESCRIPTION

 

802.11 Mode

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 preamble 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 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.

 

 

 

 

802.11

Enabling this feature can help prevent collisions in mixed-mode networks

 

Protection

(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.

 

 

 

 

Preamble

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, 802.11n Only or 802.11b/g/

 

 

n Mixed.
