LAN Setup Screen Settings

The following settings are available.

Device Name. By default, this is DGN2200v4 (the

modem router model). You can change

it to another name if you prefer.

LAN TCP/IP Setup

•

IP Address

. The LAN IP address of the modem router.

•

IP Subnet Mask

. The LAN subnet mask of the modem router. Combined with the IP

address, the IP subnet mask allows a device to know which other addresses are local to

it, and which addresses have to be reached through a gateway or modem router.

•

RIP Direction

. Router Information Protocol (RIP) allows the modem router to exchange

routing information with other routers. This setting controls how the modem router sends

and receives RIP packets. Both is the default setting. With the Both or Out Only setting,

the modem router broadcasts its routing table periodically. With the Both or In Only

setting, the modem 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 modem router sends. It recognizes both formats when receiving. By

default, the RIP function is disabled.

-

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 a DHCP Server

Usually, this check box is selected so that the modem router functions as a Dynamic Host

Configuration Protocol (DHCP) server.

•

Starting IP Address

. Specify the start of the range for the pool of IP addresses in the

same subnet as the modem router.

•

Ending IP Address

. Specify the end of the range for the pool of IP addresses in the

same subnet as the modem router.

Address Reservation

When you specify a reserved IP address for a computer on the LAN, that computer receives

the same IP address each time it accesses the modem router’s DHCP server. Assign

reserved IP addresses to servers that require permanent IP settings. See

Address

Reservation

Specify DHCP Server Settings

By default, the modem router is set up as a DHCP server. You can specify the range of

addresses that the modem router assigns. You can also use another device on your network

as the DHCP server, or specify the network settings of all of your computers.



To specify the pool of IP addresses that the modem router assigns:

1.

Select

Advanced > LAN Setup

.

2.

Make sure that the

Use Router as a DHCP Server

check box is selected.

3.

Specify the range of IP addresses.

For example, using the default addressing scheme, define a range between 192.168.0.2

and 192.168.0.254, although you might want to save part of the range for devices with

fixed addresses.

•

In the Starting IP Address field, specify the start of the range for the pool of IP

addresses in the same subnet as the modem router.

•

In the Ending IP Address field, specify the end of the range for the pool of IP

addresses in the same subnet as the modem router.

To disable the DHCP Server feature in the modem router:

1.

Select

Advanced > LAN Setup

.

2.

Clear the

Use Router as DHCP Server

check box

3.

Click

Apply

.

4.

If no DHCP server is on your network, set your computers’ IP addresses manually so that

they can access the modem 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 modem 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

.

2.

In the Address Reservation section of the screen, click the

Add

button.

3.

In the IP Address field, type the IP address to assign to the computer or server.

Choose an IP address from the modem router’s LAN subnet, such as 192.168.0.x.

4.

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.

5.

Click

Apply.

The reserved address is entered into the table.

The reserved address is not assigned until the next time the computer contacts the

modem 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 modem router can provide QoS prioritization over the wireless link and on the

Internet connection.

WMM QoS for Wireless Multimedia Applications

The modem 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.



To disable WMM QoS:

1.

Select

Advanced > Setup > QoS Setup

.

2.

Clear the

Enable WMM

check box

3.

Click

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 modem 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.

Select

Advanced > Setup > QoS Setup.

2.

Select the

Turn Internet Access QoS On

check box.

3.

Click the

Setup QoS Rule

button.

The QoS Priority Rule list displays.

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 the rules by clicking the

Delete All

button.
