Band Steering
Band Steering Enable or disable Band Steering function.
Band Steering is a technology that detects whether
the wireless client is dual-band capable. If it is, band
steering pushes the client to connect to the less-
congested 5 GHz network. It does this by actively
blocking the client’s attempts to connect with the
2.4GHz network.
Isolation
Isolation between
SSIDs
Define whether to isolate traffic between SSIDs. If
enabled, wireless clients in different SSIDs cannot
communicate with each other. Enabled by default.
Advanced Parameters
Wireless Radio Select the desired radio from the list.
Radio 1 is for 2.4 GHz, and Radio 2 is for 5 GHz.
Worldwide Mode
(802.11d)
Worldwide Mode (802.11d) enables the access point
to direct connected wireless devices to radio settings
specific to where in the world the devices are in use.
Channel Bandwidth You can select the channel bandwidth manually for
Wireless-N connections. When it is set to 20MHz, only
20MHz channel is being used.
Guard Interval Select the guard interval manually for Wireless-N
connections. The two options are Short (400
nanoseconds) and Long (800 nanoseconds). The
default is Auto.
CTS Protection
Mode
CTS (Clear-To-Send) Protection Mode boosts
the access point’s ability to catch all Wireless-G
transmissions, but it severely decreases performance.
By default, CTS Protection Mode is disabled, but the
access point will automatically enable this feature
when Wireless-G devices are not able to transmit
to the access point in an environment with heavy
802.11b traffic.
Beacon Interval The access point transmits beacon frames at regular
intervals to announce the existence of the wireless
network. Enter the interval between the transmissions
of beacon frames. The value range is between 40 and
1000 milliseconds and default is 100 milliseconds.
DTIM Interval Enter the Delivery Traffic Information Map (DTIM)
period, an integer from 1 to 255 beacons. The default
is 1 beacon.
The DTIM message is an element included in some
beacon frames. It indicates which client stations,
currently sleeping in low-power mode, have data
buffered on the access point await-ing pickup.
The DTIM period that you specify indicates how often
the clients served by this WAP device should check
for buffered data still on the access point awaiting
pickup.
For example, if you enter 1, clients check for buffered
data on the access point at every beacon. If you enter
10, clients check on every 10th beacon.
RTS Threshold Enter the Request to Send (RTS) Threshold value, an
integer from 1 to 2347. The default is 2347 octets.
The RTS threshold indicates the number of octets in
a Medium Access Control Protocol Data Unit (MPDU)
below which an RTS/CTS handshake is not performed.
Changing the RTS threshold can help control traffic
flow through the access point, especially one with a
lot of clients. If you specify a low threshold value, RTS
packets are sent more frequently, which consumes
more bandwidth and reduces the throughput of the
packet. However, sending more RTS packets can help
the network recover from interference or collisions
that might occur on a busy network, or on a network
experiencing electromagnetic interference.
