DESCRIPTION

 

DTIM Interval

Delivery Traffic Indication Message (DTIM) is the time period after which

 

 

broadcast and multicast packets are transmitted to mobile clients in the

 

 

Power Saving mode. A high DTIM value can cause clients to lose

 

 

connectivity with the network. This value can be set from 1 to 100.

 

 

 

 

802.11 Mode

Select 802.11b Only to allow only IEEE 802.11b compliant WLAN

 

 

devices to associate with the ZyXEL Device.

 

 

Select 802.11g Only to allow only IEEE 802.11g compliant WLAN

 

 

devices to associate with the ZyXEL Device.

 

 

Select 802.11n Only to allow only IEEE 802.11n compliant WLAN

 

 

devices to associate with the ZyXEL Device.

 

 

Select 802.11b/g Mixed to allow either IEEE 802.11b or IEEE 802.11g

 

 

compliant WLAN devices to associate with the ZyXEL Device. The

 

 

transmission rate of your ZyXEL Device might be reduced.

 

 

Select 802.11b/g/n Mixed to allow IEEE 802.11b, IEEE 802.11g or

 

 

IEEE802.11n compliant WLAN devices to associate with the ZyXEL

 

 

Device. The transmission rate of your ZyXEL Device 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

 

 

ZyXEL 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.

 

 

 

 

Preamble

Select a preamble type from the drop-down list box. Choices are Long or

 

 

Short. See Section 7.9.7 on page 119 for more information.

 

 

This field is configurable only when you set 802.11 Mode to 802.11b.
