Chapter 7 Wireless Table 27 Network Setting > Wireless > Others (continued) LABEL DESCRIPTION 802.11 Protection 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. Preamble 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 Section 7.10.7 on page 109 for more information. Protected Management Frames 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. Cancel Apply 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. 7.8 Channel Status Settings Use the Channel Status screen to scan WiFi channel noises and view the results. Click Network Setting > Wireless > Channel Status. The screen appears as shown. Click Scan to scan the WiFi channels. You can view the results in the Channel Scan Result section. Note: If the current channel is a DFS channel, the warning 'Channel scan process is denied because current channel is a DFS channel (Channel: 52~140). If you want to run channel scan, please select a non-DFS channel and try again.' appears. EX3510-B0 User's Guide 102
