112 Chapter 6 Wireless LAN
When you select WPA2 or WPA2-PSK in your ZyXEL Device, you can also select an option
(WPA compatible) to support WPA as well. In this case, if some of the devices support WPA
and some support WPA2, you should set up WPA2-PSK or WPA2 (depending on the type of
wireless network login) and select the WPA compatible option in the ZyXEL Device.
Many types of encryption use a key to protect the information in the wireless network. The
longer the key, the stronger the encryption. Every device in the wireless network must have
the same key.
6.2.5 One-Touch Intelligent Security Technology (OTIST)
With ZyXEL’s OTIST, you set up the SSID and 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 6.5 on page 120 for more details.
6.3 Wireless Performance Overview
The following sections introduce different ways to improve the performance of the wireless
network.
6.3.1 Quality of Service (QoS)
You can turn on Wi-Fi MultiMedia (WMM) QoS to improve the performance of voice and
video applications in the wireless network. QoS gives high priority to voice and video, which
makes them run more smoothly. Similarly, it gives low priority to many file downloads so that
they do not reduce the quality of other applications.
6.4 General Wireless LAN Screen
Note: 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.
Click Network > Wireless LAN to open the General screen.
