The QoS screen allows you to automatically give a service (such as VoIP and video) a priority level.

Click Network > Wireless LAN 2.4G or Wireless LAN 5G > QoS. The following screen appears.

Network > Wireless LAN > QoS 

Network Mode 
(Wireless LAN 
5G)

Select 11a/n mixed mode to allow IEEE802.11a and IEEE802.11n compliant WLAN devices 
to associate with the Router.

Select 11a only to allow only IEEE 802.11a compliant WLAN devices to associate with the 
Router.

Select 11a/an/ac to allow only IEEE 802.11a, IEEE802.11an and IEEE802.11ac compliant 
WLAN devices to associate with the Router.

HT (High Throughput) Physical Mode

 

- Use the fields below to configure the 802.11 wireless environment of 

your Router. 

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, 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 Router 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 Router 
to get higher data throughput. This also lowers radio interference and traffic.

Apply

Click Apply to save your changes back to the Router.

Cancel

Click Cancel to reload the previous configuration for this screen.
