Chapter 8    Quality of Service (QoS)

Use this screen to enable or disable QoS, set the bandwidth, and select to have the Router 

automatically assign priority to upstream traffic according to the IP precedence or packet length.

Click Network Setting > QoS to open the General screen.

Active QoS

Select the check box to turn on QoS to improve your network performance. 
You can give priority to traffic that the Router forwards out through the WAN interface. 

Give high priority to voice and video to make them run more smoothly. Similarly, give 

low priority to many large file downloads so that they do not reduce the quality of other 

applications. 

Traffic priority 

will be 

automatically 

assigned by

Select how the Router assigns priorities to various upstream traffic flows.
• None: Disables auto priority mapping and has the Router put packets into the 

queues according to your classification rules. Traffic which does not match any of 

the classification rules is mapped into the default queue with the lowest priority.

• Ethernet Priority: Automatically assign priority based on the IEEE 802.1p priority 

level.

• IP Precedence: Automatically assign priority based on the first three bits of the TOS 

field in the IP header.

• Packet Length: Automatically assign priority based on the packet size. Smaller 

packets get higher priority since control, signaling, VoIP, internet gaming, or other 

real-time packets are usually small while larger packets are usually best effort data 

packets like file transfers.
