Figure 73   Network > Wireless LAN > QoS 

Operating 
Mode

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

Mixed Mode - 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 Mode - 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.

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 NBG-419N is located in an 
environment prone to radio interference.

Extension 
Channel

This is set to Auto by default. 

If you select 20/40 as your Channel Bandwidth, the extension channel 
enables the NBG-419N to get higher data throughput. This also lowers 
radio interference and traffic.
