LABEL
DESCRIPTION
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.
Enable Intra-BSS 
Traffic
A Basic Service Set (BSS) exists when all communications between wireless clients or 
between a wireless client and a wired network client go through one access point (AP). 
Intra-BSS traffic is traffic between wireless clients in the BSS. When Intra-BSS is 
enabled, wireless client A and B can access the wired network and communicate with 
each other. When Intra-BSS is disabled, wireless client A and B can still access the 
wired network but cannot communicate with each other.
Output Power
Set the output power of the NBG4104 in this field. If there is a high density of APs in an 
area, decrease the output power of the NBG4104 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 NBG4104’s output power.
HT (High Throughput) Physical Mode
 
- Use the fields below to configure the 802.11 wireless environment of 
your NBG4104. 
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.
Guard Interval
Select Auto to increase data throughput. However, this may make data transfer more 
prone to errors.
Select Long to prioritize data integrity. This may be because your wireless network is 
busy and congested or the NBG4104 is located in an environment prone to radio 
interference.
