LABEL
DESCRIPTION
RTS/CTS
Data with its frame size larger than this value will perform the RTS (Request To Send)/CTS
Threshold
(Clear To Send) handshake.
Enter a value between 0 and 2347.
Fragmentation
This is the maximum data fragment size that can be sent. Enter a value between 256 and
Threshold
2346.
Auto Channel
If you set the channel to Auto in the Network Setting > Wireless > General screen,
Timer
specify the interval in minutes for how often the VMG scans for the best channel. Enter 0 to
disable the periodical scan.
Output Power
Set the output power of the VMG. If there is a high density of APs in an area, decrease the
output power to reduce interference with other APs. Select one of the following: 20%,
40%, 60%, 80% or 100%.
Beacon Interval
When a wirelessly networked device sends a beacon, it includes with it a beacon interval.
This specifies the time period before the device sends the beacon again.
The interval tells receiving devices on the network how long they can wait in low power
mode before waking up to handle the beacon. This value can be set from 50ms to 1000ms.
A high value helps save current consumption of the access point.
DTIM Interval
Delivery Traffic Indication Message (DTIM) is the time period after which broadcast and
multicast packets are transmitted to mobile clients in the Power Saving mode. A high DTIM
value can cause clients to lose connectivity with the network. This value can be set from 1
to 255.
802.11 Mode
Select 802.11b Only to allow only IEEE 802.11b compliant WLAN devices to associate with
the VMG.
Select 802.11g Only to allow only IEEE 802.11g compliant WLAN devices to associate with
the VMG.
Select 802.11n Only to allow only IEEE 802.11n compliant WLAN devices to associate with
the VMG.
Select 802.11b/g Mixed to allow either IEEE 802.11b or IEEE 802.11g compliant WLAN
devices to associate with the VMG. The transmission rate of your VMG might be reduced.
Select 802.11b/g/n Mixed to allow IEEE 802.11b, IEEE 802.11g or IEEE802.11n
compliant WLAN devices to associate with the VMG. The transmission rate of your VMG
might be reduced.
802.11
Enabling this feature can help prevent collisions in mixed-mode networks (networks with
Protection
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 VMG 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.
RIFS
Select Auto to enable the Reduced Inter-frame Spacing (RIFS) feature. It improves the
Advertisement
Device's performance by reducing the amount of dead time required between OFDM
transmissions. Select Off to disable the feature.
Preamble
Select a preamble type from the drop-down list box. Choices are Long or Short. See
Section 7.9.7 on page 109
This field is configurable only when you set 802.11 Mode to 802.11b.
RX Chain Power
Select Enable to activate the RX Chain Power Save feature. It turns off one of the Receive
Save
chains to save power when it is not in use. Select Disabled to disable this feature.
