The DHCP Client Table lists computers and other
devices that have been assigned IP addresses by the
Router. The list can be sorted by Client Name, Interface,
IP Address, and MAC Address. To select a DHCP client,
click Select. To update the on-screen information,
click Refresh. To exit this screen and return to the DMZ
screen, click Close.

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 gaming,
videoconferencing, video streaming, and Voice over
Internet Protocol (VoIP) telephony. QoS helps to ensure
optimal performance for these types of uses.

QoS (Quality of Service)
Wireless
WMM Support Wi-Fi Multimedia (WMM) is a wireless
Quality of Service feature that 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 Wireless WMM. To disable
this option, select Disabled. Otherwise, keep the default,
Enabled.
No Acknowledgement If you want to disable the
Router’s Acknowledgement option, so the Router will
not re-send data if an error occurs, then select Enabled.
Otherwise, keep the default, Disabled.
Internet Access Priority
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
Upstream Bandwidth This option sets the maximum
outgoing bandwidth that applications can use. To allow
the Router to set the maximum, keep the default, Auto.
To specify the maximum, select Manual. Then enter the
appropriate value and select Kbps or Mbps.
Category
You can define the Internet access priority level for as
many categories 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
pre-defined application or one that you add.
• Online Games Allows you to assign a priority level for
a pre-defined 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.
Summary
This lists the QoS entries you have created for your
applications and devices. Refer to “Summary” on page 24
