Chapter 13 Interfaces Table 69 Configuration > Network > Interface > WLAN LABEL DESCRIPTION 802.11 Band Select whether you will let wireless clients connect to the ZyWALL using IEEE 802.11b, IEEE 802.11g, or both. Select b Only to allow only IEEE 802.11b compliant WLAN devices to associate with the ZyWALL. Select g Only to allow only IEEE 802.11g compliant WLAN devices to associate with the ZyWALL. Channel Super Mode CTS/RTS Threshold Select b+g to allow both IEEE802.11b and IEEE802.11g compliant WLAN devices to associate with the ZyWALL. The transmission rate of your ZyWALL might be reduced. This allows you to set the operating channel depending on your particular region. Select a channel from the drop-down list box. Select this to improve data throughput on the WLAN by enabling fast frame and packet bursting. Use CTS/RTS to reduce data collisions on the wireless network if you have wireless clients that are associated with the same AP but out of range of one another. When enabled, a wireless client sends an RTS (Request To Send) and then waits for a CTS (Clear To Send) before it transmits. This stops wireless clients from transmitting packets at the same time (and causing data collisions). Fragmentation Threshold Output Power Add Edit Remove Activate Inactivate Object References # Status Name SSID A wireless client sends an RTS for all packets larger than the number (of bytes) that you enter here. Set the RTS/CTS equal to or higher than the fragmentation threshold to turn RTS/CTS off. This is the threshold (number of bytes) for the fragmentation boundary for directed messages. It is the maximum data fragment size that can be sent. Select the percentage of output power that this WLAN card is to use. If there is a high density of APs in the area, decrease the output power of the ZyWALL to reduce interference with other APs. See the product specifications for more information on your ZyWALL's output power. Click this to create a new WLAN interface. Double-click an entry or select it and click Edit to open a screen where you can modify the entry's settings. To remove an entry, select it and click Remove. The ZyWALL confirms you want to remove it before doing so. To turn on an entry, select it and click Activate. To turn off an entry, select it and click Inactivate. Select an entry and click Object References to open a screen that shows which settings use the entry. See Section 13.3.2 on page 309 for an example. This field is a sequential value, and it is not associated with any interface. This icon is lit when the entry is active and dimmed when the entry is inactive. This field displays the name of the WLAN interface. This is the SSID (Service Set IDentity) of the WLAN interface. 328 ZyWALL USG 300 User's Guide
