5.2.5 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 5.5 on page 88 for more details.
5.3 Additional Wireless Terms
The following table describes wireless network terms and acronyms used in the ZyXEL
Device.
5.4 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 WEP 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.
Click Network > Wireless LAN to open the Wireless LAN General screen.

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.
Authentication The process of verifying whether a wireless device is allowed to use the
wireless network.
Max. Frame Burst Enable this to improve the performance of both pure IEEE 802.11g and mixed
IEEE 802.11b/g networks. Maximum Frame Burst sets the maximum time that
the ZyXEL Device transmits IEEE 802.11g wireless traffic only.
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.
