Chapter 7 Wireless
DESCRIPTION
Enabling this feature can help prevent collisions in mixed-mode networks (networks with both
IEEE 802.11b and IEEE 802.11g traffic).
Select Auto to have the wireless devices transmit data after a RTS/CTS handshake. This helps
improve IEEE 802.11g performance.
Select Off to disable 802.11 protection. The transmission rate of your Zyxel Device might be
reduced in a mixed-mode network.
This field displays Off and is not configurable when you set 802.11 Mode to 802.11b Only.
Select a preamble type from the drop-down list box. Choices are Long or Short. See
7.10.7 on page 110 for more information.
This field is configurable only when you set 802.11 Mode to 802.11b or 802.11b/g Mixed.
This option is only available when using WPA2-PSK as the Security Mode and AES Encryption in
Network Setting > Wireless > General. Management frame protection (MFP) helps prevent
wireless DoS attacks.
Select Disable if you do not want to use MFP.
Select Capable to encrypt management frames of wireless clients that support MFP. Clients
that do not support MFP will still be allowed to join the wireless network, but remain
unprotected.
Select Required to allow only clients that support MFP to join the wireless network.
Click Cancel to restore the default or previously saved settings.
Click Apply to save your changes.
