The following table describes the labels in this screen. 

Network > Wireless LAN > Advanced

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 256 and 2432. 

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.

Output Power

Set the output power of the NBG4615 in this field. If there is a high density of APs 
in an area, decrease the output power of the NBG4615 to reduce interference with 
other APs. Select one of the following 100%, 90%, 75%, 50%, 25% or 10%. 
See the product specifications for more information on your NBG4615’s output 
power.

HT (High Throughput) Physical Mode

 

- Use the fields below to configure the 802.11 wireless 

environment of your NBG4615. 

Operating Mode

Choose this according to the wireless mode(s) used in your network.

Mixed - Select this if the wireless clients in your network use different wireless 
modes (for example, IEEE 802.11b/g and IEEE 802.1n modes)

Green - Select this if the wireless clients in your network uses only one type of 
wireless mode (for example, IEEEE 802.11 n only)

Channel 
Bandwidth

Select the channel bandwidth you want to use for your wireless network.

It is recommended that you select 20/40 (20/40 MHz). 

Select 20 MHz if you want to lessen radio interference with other wireless devices 
in your neighborhood.
