Chapter 7 Wireless Table 25 Network Setting > Wireless > Others (continued) LABEL Output Power Beacon Interval DESCRIPTION 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%. 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. DTIM Interval 802.11 Mode 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 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. 802.11 Protection 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. 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 VMG might be reduced in a mixed-mode network. RIFS Advertisement Preamble This field displays Off and is not configurable when you set 802.11 Mode to 802.11b Only. 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 a preamble type from the drop-down list box. Choices are Long or Short. See Section 7.9.7 on page 104 for more information. RX Chain Power Save OBSS Coexistence XPressTM Technology WPS 2.0 Apply Cancel This field is configurable only when you set 802.11 Mode to 802.11b. 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 to allow the coexistence of 20 MHz and 40 MHz Overlapping Basic Service Sets (OBSS) in wireless local area networks. 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. Select Enable to support WPS 2.0 which enhances WPS security and flexibility on configuration. Select Disabled to disable this feature. Click Apply to save your changes. Click Cancel to restore your previously saved settings. VMG4825-B10A User's Guide 97

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

and is not configurable when you set
802.11 Mode
to
802.11b
Only
.
RIFS
Advertisement
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
