PPPoE

. Some DSL-based ISPs use PPPoE (Point-to-Point Protocol over Ethernet) to establish Internet

connections. If you are connected to the Internet through a DSL line, check with your ISP to see if they use

PPPoE. If they do, you will have to enable

PPPoE

.

User Name and Password

. Enter the User Name and Password provided by your ISP.

Connect on Demand: Max Idle Time.

You can configure the Router to cut the Internet connection after it has

been inactive for a specified period of time (Max Idle Time). If your Internet connection has been terminated

due to inactivity, Connect on Demand enables the Router to automatically re-establish your connection as

soon as you attempt to access the Internet again. If you wish to activate Connect on Demand, click the radio

button. In the

Max Idle Time

field, enter the number of minutes you want to have elapsed before your Internet

connection terminates.

Keep Alive Option:

Redial Period. If you select this option, the Router will periodically check your Internet

connection. If you are disconnected, then the Router will automatically re-establish your connection. To use

this option, click the radio button next to

Keep Alive

. In the

Redial Period

field, you specify how often you want

the Router to check the Internet connection.

The default Redial Period is 30 seconds.

Optional Settings

Some of these settings may be required by your ISP. Verify with your ISP before making any changes.

Router Name

. In this field, you can type a name of up to 39 characters to represent the Router.

Host Name/Domain Name

. These fields allow you to supply a host and domain name for the Router. Some ISPs,

usually cable ISPs, require these names as identification. You may have to check with your ISP to see if your

broadband Internet service has been configured with a host and domain name. In most cases, leaving these

fields blank will work.

MTU

. MTU is the Maximum Transmission Unit. It specifies the largest packet size permitted for Internet

transmission. The default setting,

Manual

, allows you to enter the largest packet size that will be transmitted.

The recommended size, entered in the

Size

field, is 1492. You should leave this value in the 1200 to 1500 range.

To have the Router select the best MTU for your Internet connection, select

Auto

.

Network Setup

The Network Setup section changes the settings on the network connected to the Router’s Ethernet ports.

Wireless Setup is performed through the Wireless tab.

Network Address Server Settings (DHCP)

The settings allow you to configure the Router’s Dynamic Host Configuration Protocol (DHCP) server function. The

Router can be used as a DHCP server for your network. A DHCP server automatically assigns an IP address to

each computer on your network. If you choose to enable the Router’s DHCP server option, you must configure all

of your network PCs to connect to a DHCP server (the Router), and make sure there is no other DHCP server on

your network.

DHCP Server

. DHCP is enabled by factory default. If you already have a DHCP server on your network, or you

don’t want a DHCP server, then click the

Disable

radio button (no other DHCP features will be available).

Starting IP Address

. Enter a value for the DHCP server to start with when issuing IP addresses.

Because the

Router’s default IP address is 192.168.1.1, the Starting IP Address must be 192.168.1.2 or greater, but smaller

than 192.168.1.253. The default Starting IP Address is

192.168.1.100

.

Maximum Number of DHCP Users

. Enter the maximum number of PCs that you want the DHCP server to assign

IP addresses to. This number cannot be greater than 253. The default is 50.

Client Lease Time

. The Client Lease Time is the amount of time a network user will be allowed connection to the

Router with their current dynamic IP address. Enter the amount of time, in minutes, that the user will be “leased”

this dynamic IP address. After the time is up, the user will be automatically assigned a new dynamic IP address.

The default is 0 minutes, which means one day.

Static DNS

(1,2). The Domain Name System (DNS) is how the Internet translates domain or website names into

Internet addresses or URLs. Your ISP will provide you with at least one DNS Server IP Address. If you wish to use

another, type that IP Address in one of these fields. You can type up to three DNS Server IP Addresses here. The

Router will use these for quicker access to functioning DNS servers.

Time Setting

Change the time zone in which your network functions from this pull-down menu. (You can even automatically

adjust for daylight savings time.)
