DESCRIPTION
If you set the channel to Auto in the Network Setting > Wireless > General screen,
specify the interval in minutes for how often the Device scans for the best channel. Enter 0
to disable the periodical scan.
Set the output power of the Device. 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%.
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.
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.
Select 802.11b Only to allow only IEEE 802.11b compliant WLAN devices to associate with
the Device.
Select 802.11g Only to allow only IEEE 802.11g compliant WLAN devices to associate with
the Device.
Select 802.11n Only to allow only IEEE 802.11n compliant WLAN devices to associate with
the Device.
Select 802.11b/g Mixed to allow either IEEE 802.11b or IEEE 802.11g compliant WLAN
devices to associate with the Device. The transmission rate of your Device 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 Device. The transmission rate of your Device
might be reduced.
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 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.
Select a preamble type from the drop-down list box. Choices are Long or Short. See
Section 6.10.7 on page 97
This field is configurable only when you set 802.11 Mode to 802.11b.
Select Auto to enable the Reduced Inter-frame Spacing (RIFS) feature. It improves the
Device's performance by reducing the amount of dead time required between OFDM
transmissions. Select Off to disable the feature.
Select this to support WPS 2.0 which enhances WPS security and flexibility on
configuration.
Select Enable to activate the RX Chain Power Save feature. It turns off one of the Receive
chains to save power when it is not in use. Select Disabled to disable this feature.
Select Enable for higher speeds, especially if you have both IEEE 802.11b and IEEE
802.11g wireless clients. The wireless clients do not have to support XPress™ Technology,
although the performance enhancement is greater if they do. Select Disabled to disable
this feature.
