8.6 Technical Reference
This section discusses WiFi in depth.
8.6.1 WiFi Network Overview
WiFi networks consist of WiFi clients, access points and bridges.
• A WiFi client is a radio connected to a user’s computer.
• An access point is a radio with a wired connection to a network, which can connect with numerous
WiFi clients and let them access the network.
• A bridge is a radio that relays communications between access points and WiFi clients, extending a
network’s range.
802.11 Mode For 2.4 GHz frequency WiFi devices:
•Select 802.11b Only to allow only IEEE 802.11b compliant WiFi devices to associate with the
Zyxel Device.
•Select 802.11g Only to allow only IEEE 802.11g compliant WiFi devices to associate with the
Zyxel Device.
•Select 802.11n Only to allow only IEEE 802.11n compliant WiFi devices to associate with the
Zyxel Device.
•Select 802.11b/g Mixed to allow either IEEE 802.11b or IEEE 802.11g compliant WiFi devices
to associate with the Zyxel Device. The transmission rate of your Zyxel Device might be
reduced.
•Select 802.11b/g/n Mixed to allow IEEE 802.11b, IEEE 802.11g or IEEE 802.11n compliant WiFi
devices to associate with the Zyxel Device. The transmission rate of your Zyxel Device might
be reduced.
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.
This field displays Off and is not configurable when you set 802.11 Mode to 802.11b Only.
Preamble Select a preamble type from the drop-down list box. Choices are Long or Short. See Section
8.6.6 on page 116 for more information.
This field is configurable only when you set 802.11 Mode to 802.11b.
Protected
Management
Frames
WiFi with Protected Management Frames (PMF) provides protection for unicast and Multicast
management action frames. Unicast management action frames are protected from both
eavesdropping and forging, and Multicast management action frames are protected from
forging. Select Capable if the WiFi client supports PMF, then the management frames will be
encrypted. Select Required to force the WiFi client to support PMF; otherwise the
authentication cannot be performed by the Zyxel Device. Otherwise, select Disabled.
Auto Switch Off Click this to enable Auto Switch Off and configure the next field.
Auto Switch Off
Interval
Select 0,15, 30, 45 or 60 minutes from the drop down menu. The default setting is 30 minutes.
Select 0 minute to disable the Auto Switch Off Interval.
Cancel Click Cancel to restore your previously saved settings.
Apply Click Apply to save your changes.
