exposed to the Internet for use of a special-purpose
service such as Internet gaming or videoconferencing°
DMZ hosting forwards all the ports at the same time to
one PC° The Port Range Forwarding feature is more secure
because it only opens the ports you want to have opened,
while DMZ hosting opens all the ports of one computer,
exposing the computer to the Internet°

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°

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° If you would
like to disable this feature, select
Disabled
° Otherwise,
keep the default,

If you want to disable the
Router’s Acknowledgement feature, so the Router will not

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°
