Set Up Quality of Service (QoS)
Quality of Service (QoS) is an advanced feature that can be used to prioritize some types of
traffic ahead of others. The N300 wireless modem router can provide QoS prioritization over
the wireless link and on the Internet connection.
The N300 wireless modem router supports Wi-Fi Multimedia Quality of Service (WMM QoS)
to prioritize
wireless voice and video traffic over the wireless link. WMM QoS provides
prioritization of wireless data packets from different applications based on four access
categories: voice, video, best effort, and background. For an application to receive the
benefits of WMM QoS, both it and the client running that application need to be WMM
enabled. Legacy applications that do not support WMM, and applications that do not require
QoS, are assigned to the best effort category, which receives a lower priority than voice and
video.
Configure QoS for Internet Access
To specify prioritization of traffic, you need to add or create a policy for the type of
traffic:
To display the QoS Setup screen, from the main menu, select Advan
ced > QoS Setup.
WMM QoS is enabled by default. You can disable it by selecting QoS Setup from the main
menu, clearing the Enable WMM (Wi-Fi multi-media Settings) check box, and clicking
Apply.
You can give prioritized Internet access to the following types of traffic:
• For specific applications or online games, see Qo
S for Applications and Online Gaming
on page 119.
• For QoS on individual Ethernet LAN ports of the N300 wireless modem router, see Qo
S
for a Router LAN Port on p
age 120.
• For QoS from a specific device by MAC address, see QoS for a MA
C Address on
page 121.
