LABEL DESCRIPTION
2.4G Advanced Settings / 5G Advanced Settings
Hide WiFi
Network Name Select this check box to hide the wireless band’s network name (SSID) in the outgoing beacon
frame so a station cannot obtain the SSID through scanning using a site survey tool or any
wireless clients.
Note: This setting only applies to the main 2.4G and 5G wireless networks. It does not
apply to the guest and extra wireless networks configured in the Network
Setting > Wireless > Guest WiFi screen.
Channel Select a specific channel the EMG uses for the wireless band. Select Auto to have the EMG
automatically determine a channel to use.
802.11 Mode Select 802.11b Only to allow only IEEE 802.11b compliant WLAN devices to associate with the
EMG.
Select 802.11g Only to allow only IEEE 802.11g compliant WLAN devices to associate with the
EMG.
Select 802.11n Only to allow only IEEE 802.11n compliant WLAN devices to associate with the
EMG.
Select 802.11b/g Mixed to allow either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to
associate with the EMG. The transmission rate of your EMG 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 EMG. The transmission rate of your EMG might be reduced.
RTS/CTS
Threshold Data with its frame size larger than this value will perform the RTS (Request To Send)/CTS (Clear
To Send) handshake.
Enter a value between 0 and 2347.
Fragmentation
Threshold This is the maximum data fragment size that can be sent. Enter a value between 256 and 2346.
Output Power Set the output power of the EMG. 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 Protection 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 EMG 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 .
Preamble Select a preamble type from the drop-down list box. Choices are Long or Short . See Section
7.8.7 on page 94 for more information.
This field is configurable only when you set 802.11 Mode to 802.11b .
