192.168.1.2 and 192.168.1.254, although you might want to save part of the range for
devices with fixed addresses.
The router delivers the following parameters to any LAN device that requests DHCP:
An IP address from the range you have defined
Subnet mask
Gateway IP address (the router’s LAN IP address)
Primary DNS server (if you entered a primary DNS address in the Internet Setup screen;
otherwise, the router’s LAN IP address)
Secondary DNS server (if you entered a secondary DNS address in the Internet Setup
screen)
To use another device on your network as the DHCP server, or to specify the network
settings of all of your computers, clear the
Use Router as DHCP Server
check box and click
Apply
. Otherwise, leave this check box selected. If this service is not enabled and no other
DHCP server is available on your network, set your computers’ IP addresses manually or
they will not be able to access the router.
Address Reservation
When you specify a reserved IP address for a computer on the LAN, that computer always
receives the same IP address each time it accesses the router’s DHCP server. Assign
reserved IP addresses to computers or servers that require permanent IP settings.
To reserve an IP address:
1.
In the Address Reservation section of the screen, click the
Add
button.
2.
In the IP Address field, type the IP address to assign to the computer or server. (Choose an
IP address from the router’s LAN subnet, such as 192.168.1.x.)
3.
Type the MAC address of the computer or server.
Tip:
If the computer is already on your network, you can copy its MAC
address from the Attached Devices screen and paste it here.
4.
Click
Apply
to enter the reserved address into the table.
The reserved address is not assigned until the next time the computer contacts the
router’s DHCP server. Reboot the computer, or access its IP configuration and force a
DHCP release and renew.
To edit or delete a reserved address entry, select the radio button next to the reserved
address you want to edit or delete. Then click
Edit
or
Delete
.

Quality of Service (QoS) Setup
QoS is an advanced feature that can be used to prioritize some types of traffic ahead of
others. The N150R router can provide QoS prioritization over the wireless link and on the
Internet connection. To configure QoS, use the QoS Setup screen.
Select
Setup > Quality of Service
to display the following screen:
Enable WMM QoS for Wireless Multimedia Applications
The N150R 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 have to have 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.
WMM QoS is enabled by default. You can disable it in the QoS Setup screen by clearing the
Enable WMM
check box and clicking
Apply
.
Set Up QoS for Internet Access
You can give prioritized Internet access to the following types of traffic:
Specific applications
Specific online games
Individual Ethernet LAN ports of the router
A specific device by MAC address
To specify prioritization of traffic, create a policy for the type of traffic and add the policy to the
QoS Policy table in the QoS Setup screen. For convenience, the QoS Policy table lists many
common applications and online games that can benefit from QoS handling.
QoS for Applications and Online Gaming
To create a QoS policy for applications and online games:
1.
In the QoS Setup screen, select the
Turn Internet Access QoS On
check box.

2.
Click the
Setup QoS Rule
button to see the existing priority rules.
You can edit or delete a rule by selecting its radio button and clicking either the
Edit
or
Delete
button. You can also delete all of the rules by simply clicking the
Delete All
button.
3.
To add a priority rule, scroll down to the bottom of the QoS Setup screen and click
Add
Priority Rule
to display the following screen:
4.
In the QoS Policy for field, type the name of the application or game.
5.
In the Priority Category list, select either
Applications
or
Online Gaming
. In either case, a
list of applications or games displays in the list.
6.
You can select an existing item from the list, or you can scroll and select
Add a New
Application
or
Add a New Game,
as applicable.
If you add an entry, the Priority Rules screen expands.
a.
In the QoS Policy for field, enter a name for the new application or game.

b.
In the Connection Type list, select either
TCP,
UDP,
or both (
TCP/UDP
). Specify the
port number or range of port numbers that the application or game uses.
7.
From the Priority list, select the priority for Internet access for this traffic relative to other
applications and traffic. The options are Low, Normal, High, and Highest.
8.
Click
Apply
to save this rule to the QoS Policy list and return to the QoS Setup screen.
QoS for a Router LAN Port
To create a QoS policy for a device connected to one of the router’s LAN ports:
1.
Select
Setup > Quality of Service
to display the QoS Setup screen. Select the
Turn
Internet Access QoS On
check box.
2.
Click the
Setup QoS Rule
button.
3.
Click the
Add Priority Rule
button.
4.
From the Priority Category list, select
Ethernet LAN Port
.
5.
From the LAN port list, select the LAN port.
6.
From the Priority list, select the priority for Internet access for this port’s traffic relative to
other applications. The options are Low, Normal, High, and Highest.
7.
Click
Apply
to save this rule to the QoS Policy list and return to the QoS Setup screen.
8.
In the QoS Setup screen, click
