Chapter 7 Wireless Table 21 Network Settings > Wireless > Others LABEL 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. 802.11 Protection 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. 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 ZyXEL Device might be reduced in a mixed-mode network. Preamble 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 box. Choices are Long or Short. See Section 7.9.7 on page 123 for more information. Back Apply Cancel This field is configurable only when you set 802.11 Mode to 802.11b. Click this to return to the previous screen without saving. Click Apply to save your changes. Click Cancel to restore your previously saved settings. 7.9 Technical Reference This section discusses wireless LANs in depth. For more information, see the appendix. 7.9.1 Wireless Network Overview Wireless networks consist of wireless clients, access points and bridges. VSG1435-B101 Series User's Guide 115
