PARAMETER
DEFINITION
54g Mode
(2.4 GHz and
802.11n/EWC disabled
only)
For
54g mode
, you can select
Automatic
,
802.11g Performance
, or
802.11b
Only
. This option is only visible when
802.11n mode
is set as
Disabled
.
54g Protection
(2.4 GHz and
802.11n/EWC disabled
only)
When set to
Automatic, the gateway will use RTS/CTS to improve the 802.11g
performance in 802.11 mixed environments.
When set to
Disabled
, the 802.11g performance will be maximized under
most conditions while the other 802.11 modes (802.11b, etc.) will be
secondary.
This option is only visible when
802.11n mode
is set as
Disabled
.
Afterburner Technology
(Both 2.4 GHz and 5GHz
when 802.11n/EWC
disabled only)
Afterburner is a 125HSM (125 High Speed Mode) speed enhancement
technology for 802.11g/b.
Preamble Type
(2.4 GHz and
802.11n/EWC disabled
only)
If you are not using any 802.11b devices in your network, set the
Preamble
Type
to
Short
for optimum performance.
The
Long
Preamble type should be used when both 802.11g and 802.11b
devices exist on your network.
Preamble Type defines the length of the Cyclic Redundancy Check (CRC)
block for communication between the gateway and wireless clients. The
preamble consists of the Synchronization and Start Frame Delimiter (SFD)
fields.
The sync field is used to indicate the delivery of a frame to wireless stations,
to measure frequency of the radio signal, to perform corrections if needed.
The SFD at the end of the Preamble is used to mark the start of the frame.
Regulatory Mode
(5 GHz only)
Select:
Disabled
,
802.11h
or
802.11d
The default is
Disabled
.
Pre-Network Radar check
(5 GHz only)
Available only in the
802.11h
Regulatory Mode, see last setting.
The default is: -1
TPC Migration (db)
(5 GHz only)
Select:
0
(
off
),
2
,
3
or
4
The default is 0(off)
Transmit Power
Select:
20%
,
40%
,
60%
,
80%
or
100%
The Power level sets the strength of the wireless signal that the gateway
transmits. If you live in an area where your wireless signal could overlap with
other wireless networks use a lower setting in order to reduce the amount of
interference.
The default setting is 100%.
WMM
(
WiFi Multimedia
)
WMM (WiFi Multimedia) maintains the priority of audio, video and voice, over
other applications which are less time critical by ensuring that data from
applications that require better throughput and performance are inserted in
queues with higher priority.
Select whether WMM is:
Auto
,
Disabled
or
Enabled
Before you disable WMM, you should understand that all QoS queues or
traffic classes relate to wireless do not take effects.
WMM No Acknowledgement
This setting is only available when
WMM
(
WiFi Multimedia
) is set to
Auto
or
Enabled
.
By default, the 'Ack Policy' for each access category is set to
Disabled
,
meaning that an acknowledgement packet is returned for every packet
received. This provides a more reliable transmission but increases traffic load,
which decreases performance.
