DESCRIPTION
Wireless Advanced Setup
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
The threshold (number of bytes) for the fragmentation boundary for directed messages. 
It is the maximum data fragment size that can be sent. Enter an even number between 
256 and 2346.
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 20 to 1024 ms. A high value 
helps save current consumption of the access point. 
DTIM Period
Delivery Traffic Indication Message (DTIM) is the time period after which broadcast and 
multicast packets are transmitted to mobile clients in the Active Power Management 
mode. A high DTIM value can cause clients to lose connectivity with the network. This 
value can be set from 1 to 10.
Preamble Type
A preamble affects the timing in your wireless network. There are two preamble modes: 
long and short.
 
If a device uses a different preamble mode than the NBG-418N does, it 
cannot communicate with the NBG-418N.
CTS Protection
When set to None, the NBG-418N protects wireless communication against interference.
Select Auto to let the NBG-418N determine whether to turn this feature on or off in the 
current environment. 
Tx Power
This field controls the transmission power of the NBG-418N. When using the NBG-418N 
with a notebook computer, select a lower transmission power level when you are close to 
the AP in order to conserve battery power.
