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 2432. 

Fragmentatio
n 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.

This field is not available when Super Mode is selected.

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 20ms to 1000ms. A high value helps save 
current consumption of the access point. 

DTIM

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 100.

Preamble

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-417N does, it cannot communicate with the NBG-
417N.
