Applications and Gaming > QoS
Quality of Service (QoS) is a method that assigns priority
to specific types of network traffic, which often are
demanding, real-time applications, such as online gaming,
VoIP calls, video streaming, and videoconferencing . QoS
can mark packets to designate different levels of priority,
so it helps to ensure optimal performance for the most
important, real-time applications .
QoS is only applied to traffic streams that are uploaded to
the Internet . QoS cannot be guaranteed after the traffic
streams reach the Internet .

QoS (Quality of Service)
Wireless
WMM Support The Wi-Fi MultiMedia (WMM) feature is a
wireless QoS feature based on the IEEE 802 .11e standard .
WMM improves quality for audio, video, and voice
applications by prioritizing wireless traffic . To use this
feature, the wireless client devices in your network must
support WMM . To disable this option, select Disabled .
Otherwise, keep the default, Enabled .
No Acknowledgement If you want the router to re-send
data if an error occurs, keep the default, Disabled . If you
do not want the router to re-send data if an error occurs,
select Enabled .
Internet Access Priority
The router is the interface between the local network and
the Internet . The user can configure the router to assign
higher priority for these categories: Applications, Online
Games, MAC Address, and Voice Device .
In this section, you can set the bandwidth priority for a
variety of applications and devices . There are four levels
of priority: High, Medium, Normal, or Low . When you set
priority, do not set all applications to High, because this will
defeat the purpose of allocating the available bandwidth .
If you want to select below-normal bandwidth, select

Low . Depending on the application, a few attempts may
be needed to set the appropriate bandwidth priority .
Enabled/Disabled To use the QoS policies you set, select
Enabled . Otherwise, keep the default, Disabled .
Upstream Bandwidth
The Upstream Bandwidth feature sets the maximum
outgoing bandwidth that applications can use . The
default, Auto, allows the router to set the maximum . The
router sets speeds that are multiples of 512 Kbps . Here are
a couple of examples:
•
If the router auto-detects an upstream speed between
512 Kbps and 1024 Kbps, it will set the maximum at
512 Kbps .
•
If the router auto-detects an upstream speed of 2300
Kbps, it will set the maximum at 2048 Kbps (512 Kbps
x 4) .
Upstream Bandwidth This option sets the maximum
outgoing bandwidth of your Internet connection . To allow
the router to detect the maximum, keep the default, Auto .
To specify the maximum, select Manual . Then enter the
appropriate bandwidth and select Kbps or Mbps .
NOTE: If the maximum bandwidth is too high,
then the router cannot apply QoS properly, and
there will be adverse QoS issues .
Category
You can define the Internet access priority level for as
many selections as you want . The Summary section will
display all of the priority selections that you enter . Select
from the following categories:
•
Applications Allows you to assign a priority level for a
predefined application or one that you add .
•
Online Games Allows you to assign a priority level for
a preset game or one that you add .
•
MAC Address This option lets you prioritize network
traffic based on the device that is accessing the
network . For example, if you want your gaming
console to have higher priority accessing the Internet
than your computer, you can assign their priority levels
using their respective MAC addresses .
•
Voice Device Voice devices require a higher priority
level . You can assign a higher priority level to voice
devices using their respective MAC addresses .

This lists the QoS entries you have created for your
applications and devices . Go to "Summary" on page 40
