DESCRIPTION

 

 

Preamble

Select Long preamble if you are unsure what preamble mode the wireless adapters

 

support, and to provide more reliable communications in busy wireless networks.

 

Select Short preamble if you are sure the wireless adapters support it, and to

 

provide more efficient communications.

 

Select Dynamic to have the ZyXEL Device automatically use short preamble when

 

wireless adapters support it, otherwise the ZyXEL Device uses long preamble.

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 Mixed to allow either IEEE802.11b or IEEE802.11g compliant WLAN devices

 

to associate with the ZyXEL Device. The transmission rate of your ZyXEL Device

 

might be reduced.

Enable 802.11g+

Select the Enable 802.11g+ mode checkbox to allow any ZyXEL WLAN devices

mode

that support this feature to associate with the ZyXEL Device at higher transmission

 

speeds. This permits the ZyXEL Device to transmit at a higher speed than the

 

802.11g Only mode.

Max. Frame

Enable Maximum Frame Burst to help eliminate collisions in mixed-mode networks

Burst

(networks with both IEEE 802.11g and IEEE 802.11b traffic) and enhance the

 

performance of both pure IEEE 802.11g and mixed IEEE 802.11b/g networks.

 

Maximum Frame Burst sets the maximum time, in micro-seconds, that the ZyXEL

 

Device transmits IEEE 802.11g wireless traffic only.

 

Type the maximum frame burst between 0 and 1800 (650, 1000 or 1800

 

recommended). Enter 0 to disable this feature.

6.5 OTIST

In a wireless network, the wireless clients must have the same SSID and security settings as the access point (AP) or wireless router (we will refer to both as “AP” here) in order to associate with it. Traditionally this meant that you had to configure the settings on the AP and then manually configure the exact same settings on each wireless client.

OTIST (One-Touch Intelligent Security Technology) allows you to transfer your AP’s SSID and WPA-PSK security settings to wireless clients that support OTIST and are within transmission range. You can also choose to have OTIST generate a WPA-PSK key for you if you didn’t configure one manually.

Note: OTIST replaces the pre-configured wireless settings on the wireless clients.

6.5.1 Enabling OTIST

You must enable OTIST on both the AP and wireless client before you start transferring settings.
