N450 Wireless Router WNR2500
Note:
If you change the LAN IP address of the router while connected
through the browser, you are disconnected. If this situation occurs,
you must open a new connection to the new IP address and log in
again.
To change the LAN settings:
1.
Select
ADVANCED > Setup > LAN Setup
.
A screen similar to the following displays:
2.
Enter the settings that you want to customize.
For more information, see
LAN Setup Screen Settings
on page

Click the

button.
LAN Setup Screen Settings
The following settings are available in the LAN TCP/IP section:
IP Address
. The LAN IP address of the router (by default, 192.168.1.1).
IP Subnet Mask
. The LAN subnet mask of the router (by default, 255.255.255.0).
Combined with the IP address, the IP subnet mask allows a device to know which other
addresses are local to it, and which must be reached through a gateway or router.
RIP Direction
. Router Information Protocol (RIP) enables a router to exchange routing
information with other routers. This setting controls how the router sends and receives
RIP packets. Both is the default setting. With the Both or Out Only setting, the router

broadcasts its routing table periodically. With the Both or In Only setting, the router
incorporates the RIP information that it receives.
RIP Version
. This setting controls the format and the broadcasting method of the RIP
packets that the router sends. It recognizes both formats when receiving. By default, the
RIP function is disabled. Three RIP versions exist:
-
RIP-1 is universally supported. It is adequate for most networks, unless you have an
unusual network setup.
-
RIP-2 carries more information. Both RIP-2B and RIP-2M send the routing data in
RIP-2 format.
-
RIP-2B uses subnet broadcasting.
-
RIP-2M uses multicasting.
Use Router as DHCP Server
By default, the router functions as a DHCP server, enabling it to assign IP, DNS server, and
default gateway addresses to all computers and devices that are connected to the router’s
LAN. The assigned default gateway address is the LAN address of the router. The router
assigns IP addresses to the attached computers and devices from a pool of addresses
specified on the LAN Setup screen. Each pool address is tested before it is assigned to avoid
duplicate addresses on the LAN. For most applications, the default DHCP and TCP/IP
settings of the router function well.
You can specify the pool of IP addresses that are assigned by setting the starting IP address
and ending IP address. These addresses should be part of the same IP address subnet as
the router’s LAN IP address. Using the default addressing scheme, the default range is
192.168.1.2–192.168.1.254, although you might want to save part of this range for devices
with fixed addresses.
Starting IP Address
. Specify the start of the range for the pool of IP addresses in the
same subnet as the router. The IP address 192.168.1.2 is the default starting address.
Ending IP Address
. Specify the end of the range for the pool of IP addresses in the
same subnet as the router. The default ending IP address is 192.168.1.254.
The router delivers the following parameters to any LAN device that requests DHCP
information:
IP address from the range that you have defined
Subnet mask
Gateway IP address (the router’s LAN IP address)
DNS server address (if you entered a primary DNS address on the Internet Setup screen;
otherwise, the router’s LAN IP address)
You can use another device on your network as the DHCP server or you can manually
configure the network settings of all of your computers and devices.
To disable the DHCP server feature:
1.
Select
ADVANCED > Setup > LAN Setup
.

Clear the

check box.
3.
Click the
Apply
button.
If the DHCP service is not enabled on the router and no other DHCP server is available on
your network, you must set your computers’ IP addresses manually or your computers are
not able to access the router.
Set Up Address Reservation
When you specify a reserved IP address for a computer or device on the LAN, that computer
or device always receives the same IP address each time it accesses the router’s DHCP
server. Reserved IP addresses should be assigned to computers or servers that require
permanent IP settings.
To reserve an IP address:
1.
Select
ADVANCED > Setup > LAN Setup
.
The LAN Setup screen displays.
2.
In the Address Reservation section of the screen, click the
Add
button.
A screen similar to the following displays:
3.
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.)
Tip:
If the computer is already on your network, you can select the associated
radio button in the Address Reservation Table. The computer’s
information is automatically copied into the IP Address, MAC Address,
and Device Name fields.

4.
Type the MAC address of the computer or server.
5.
Type a name for the computer or server.
6.
Click the
Add
button.
The address is added to the Address Reservation Table on the LAN Setup screen.
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:
1.
Select
ADVANCED > Setup > LAN Setup
.
The LAN Setup screen displays.
2.
In the Address Reservation Table, select the radio button next to the address that you want
to edit or delete, and do one of the following:
To delete a reserved address entry, click the
Delete
button.
The address is removed from the table.
To edit a reserved address entry, click the
Edit
button.

QoS Setup
Quality of Service (QoS) is an advanced feature that you can use to prioritize some types of
traffic ahead of others. The router can provide QoS prioritization over the wireless link and on
the Internet connection. You use the QoS Setup screen to set up QoS features.
Wi-Fi Multimedia Quality of Service for Wireless Traffic
The 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 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, and the Enable WMM (Wi-Fi Multimedia) settings check
box is selected. NETGEAR recommends that you leave this setting as it is for full 802.11n
wireless rate support. You can disable it in the QoS Setup screen by clearing this check box
and clicking the Apply button.

Quality of Service Priority Rules and 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, you need to 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.
By default, QoS is disabled for Internet traffic, the default QoS rules and any custom QoS
rules that you created are not activated, and no traffic is prioritized.
To enable QoS for Internet traffic and activate the QoS rules:
1.
Select
ADVANCED > Setup > QoS Setup
.
A screen similar to the following displays:
2.
Select the
Turn Internet Access QoS On
check box.
3.
Click the
Apply
button.
The following sections describe how to manage and create QoS rules, which are also
referred to as QoS policies.
Manage QoS Rules
The following procedure refers to preconfigured and custom QoS rules. For information
about how to create custom QoS rules, see the sections following this section.
