NB6Plus4Wn Quality of Service Setup Guide
The following Quality of Service (QoS) settings offer a basic setup e ample, setting up 3 devices connecting
to an NB6Plus4Wn router, one with the highest priority QoS priority data traffic, one with medium priority
QoS priority data traffic and the other with the lowest priority QoS priority data traffic flow. All other data
packet traffic through the router assumes a default best effort setting.
Quality of Service refers to the reservation of bandwidth resources on the Nb6Plus4Wn router to provide
different priorities to different applications, users, or data flows, or to guarantee a certain level of
performance to a data flow.
In this implementation Quality of Service employs DSCP – Differentiated Services Code Point – a computer
networking architecture that specifies a simple, scalable and coarse-grained mechanism for classifying,
managing network traffic.
This e ample guide sets up QoS with three devices (VoIP ATA, gaming console and laptop) connecting via
ethernet cable and via wireless to the NB6Plus4Wn router. Before Quality of Service can be implemented the
first step involves reserving an IP address for each device linking the MAC address of each device to each IP
address.

QoS Setup Part 1: Reserving an IP address
It is necessary to reserve an IP address for a device that is connecting to the NB6Plus4Wn router so that the
QoS settings can manage each device and set data packet traffic priority by MAC and IP address.
1. Navigate to http://192.168.1.1 in a web browser.
2. Enter 'admin' (without quotes) for both the username and password and click Ok.
3. Select Advanced > Local Network > DHCP Server.
4. Press the Reserved IP Address List button.

5. Enter the MAC address of the computer/device you are connecting to the router. The MAC address is
a 12 character set of numbers and letters (A-F), with every 2 characters separated by a colon.
6. Enter the IP address of the computer/device. This is the local address in the range of 192.168.1.
where = 2 to 254.
7. Press the Apply button.

8. Complete steps 4 through 7 for each device connected to the NB6 series router. Each entry will be
listed in the Static IP Lease List as shown below.
