Description
Defines the refresh time in minutes for rescans which
finds the best available channel for use on your
wireless network. When configured for auto mode, the
timer value specifies how often to re-analyze the
spectrum to select a low interference channel. Note:
auto channel rescan will only occur when there are no
actively connected devices.
Not currently used.
•
Auto
Enables 802.11n/EWC bandwidth
•
Disabled
Disables 802.11n/EWC bandwidth
Bandwidth of the 802.11n/EWC configuration, either
20MHz or 40MHz. 802.11n/EWC must be selected.
Selects the control sideband when Bandwidth of
40MHz is selected. 802.11n/EWC must be set to Auto.
The transfer rate from the zNID to the wireless client.
When Auto is selected the zNID uses the fastest
mutually support rate which can be used with the
current signal strength and noise levels. Fixed rates
limit the maximum rate to the specified value. Auto is
the recommended setting.
802.11n protection is a physical level protection which
allows 802.11n devices to transmit a Clear-to-send
(CTS) frame to itself to ensure that the neighboring
legacy devices will use the timing information to
protect 802.11n frames which follow. Auto is the
recommended setting.
802.11n only mode is enabled to prevent low speed
clients (such as 802.11b) from wasting time with low
speed transmissions. WiFi is a time division duplexed
technology, meaning that it is a half duplex ping-pong
type scheme. The system capacity goes WAY DOWN
when a low speed client is connected.
•
On: Prevents 802.11b/g clients from connecting
•
Off: Allows 802.,11b/g clients as well as 802.11n
clients
RIFS (Reduced Inter-Frame Spacing) reduces the
amount of time (unused time) between Orthogonal
Frequency-Division Multiplexing (ODFM)
transmission to improve performance. 802.11n/EWC
must be selected.
