Chapter 8 Wireless LAN 8.2.5 One-Touch Intelligent Security Technology (OTIST) With ZyXEL's OTIST, you set up the SSID and the encryption (WEP or WPA-PSK) on the ZyXEL Device. Then, the ZyXEL Device transfers them to the devices in the wireless networks. As a result, you do not have to set up the SSID and encryption on every device in the wireless network. The devices in the wireless network have to support OTIST, and they have to be in range of the ZyXEL Device when you activate it. See Section 8.5 on page 111 for more details. 8.3 Additional Wireless Terms The following table describes wireless network terms and acronyms used in the ZyXEL Device's Web Configurator. Table 29 Additional Wireless Terms TERM DESCRIPTION RTS/CTS Threshold In a wireless network which covers a large area, wireless devices are sometimes not aware of each other's presence. This may cause them to send information to the AP at the same time and result in information colliding and not getting through. By setting this value lower than the default value, the wireless devices must sometimes get permission to send information to the ZyXEL Device. The lower the value, the more often the devices must get permission. If this value is greater than the fragmentation threshold value (see below), then wireless devices never have to get permission to send information to the ZyXEL Device. Preamble A preamble affects the timing in your wireless network. There are two preamble modes: long and short. If a device uses a different preamble mode than the ZyXEL Device does, it cannot communicate with the ZyXEL Device. Authentication The process of verifying whether a wireless device is allowed to use the wireless network. Fragmentation Threshold A small fragmentation threshold is recommended for busy networks, while a larger threshold provides faster performance if the network is not very busy. 8.4 General WLAN Screen " If you are configuring the ZyXEL Device from a computer connected to the wireless LAN and you change the ZyXEL Device's SSID or security settings, you will lose your wireless connection when you press Apply to confirm. You must then change the wireless settings of your computer to match the ZyXEL Device's new settings.
