Router Basics

Back Panel

The back panel is divided into three sections: LAN, WAN, and Reset.

• The four Local Area Network (LAN) ports are where you connect your LAN
computers, print servers, hubs/switches, etc.

• The Wide Area Network (WAN) ports are where you connect your cable/xDSL
modem. You will only use one WAN port at a time.

• The Reset button can be used to reboot the router if it is experiencing problems. If
you press and hold the reset button for less than four seconds, the router will reboot
with your settings and configurations intact. If you hold the reset button for more
than four seconds, the router will reset itself to the factory default settings and you
will lose all your settings and configurations.

Getting Started

NOTE: The information in the following section as well as the information in Chapter 2:
Quick Setup is covered on the Quick Installation Guide that accompanies this manual. If
you have already performed the steps in the Quick Installation Guide, you can proceed
to Chapter 3: General Settings.

Setting Up Your LAN

1. Make sure all network devices are turned off.

2. Plug the power adapter into the 12VDC port on the back of the router. Plug the other
end into an available power source. The green PWR LED on the router should now be
lit.

3. Using an RJ-45 Ethernet cable, connect each of your network devices to one of the
four LAN ports (labeled 1 through 4) on the router.

4. Using an RJ-45 Ethernet cable, connect your xDSL or Cable modem to one of the
router’s WAN ports (labeled MDI-II and MDI-X). You need to know what type of
modem port and connection cable you are using.

NOTE: After connecting your modem to your WAN port, check the WAN LNK/ACT
LED on the front of the router. If the LED is lit, you have selected the proper WAN port.
If the WAN LNK/ACT LED is not lit, try plugging your cable into the other WAN port.

router’s default IP address (192.168.2.1) and press Enter.

NOTE: Your default home page may not load properly since the router has not been
configured. Enter the router’s IP address regardless of what appears on your screen.

2. Once the website has loaded, click the Login button. By default, there is NO
password. You should, however, input a password as soon as possible (see Password
Settings on page 19 for details). You will now be on the router’s web-based
management home page.

Chapter 2: Quick Setup

The Quick Setup feature will allow you to start sharing your Internet connection as
quickly as possible. Advanced features such as passwords or firewalls can not be
configured through Quick Setup.

BEFORE YOU BEGIN: Make sure that you know what type of Internet connection your
ISP uses: Cable Modem, Fixed-IP xDSL, Point-To-Point Protocol over Ethernet (PPPoE),
or Point-to-Point Tunneling Protocol (PPTP). Then see Broadband Type on page 12 to
find out the information that you will need to know about your specific connection.
Make sure that you have this information onhand prior to running Quick Setup. See
Appendix A for suggestions on how to find some of this information. Contact your
Internet Service Provider if you encounter difficulties finding this information.

From the router homepage, select Quick Setup.

Time Zone

The Time Zone screen allows you to set the time zone you are operating in, as well as set
up daylight savings time (optional). The time zone information will affect router
functions such as log entries and firewall settings.

When you are satisfied with your Time Zone settings, click Next to proceed to the
Broadband Type page.

Parameter Description

Set Time Zone Select the time zone of the country you are in.

Enable Daylight Savings If enabled, the router will take daylight savings into

effect.

Start Daylight Savings Time The date daylight savings begins (if enabled).

End Daylight Savings Time The date daylight savings ends (if enabled).

12

Broadband Type

The Broadband Type page requires you to select the method your ISP uses to connect
you to the Internet.

For tips on where to find the information required by the router, see Appendix A. If you

are unsure of what type of connection you are using or of where to find any of the
information required by the router, contact your ISP.

Select your connection type and proceed to the appropriate IP Address Info page.

13

Cable Modem

If you are using a cable modem, your ISP will automatically provide you with an IP
address. Some ISPs may require that you fill in additional information, such as the Host
Name and MAC Address. If your ISP does not require this information, click OK to
complete the configuration.

When you are satisfied with your IP address settings, click the OK button.
Congratulations! You have completed the basic router configuration required for a Cable

the MAC address from the adapter and apply it to
the router so that the ISP sees the MAC address it is
expecting when you connect to the Internet. (You
must be using the computer with the intial adapter
for this to work) You should record this information
so that you will not lose your ability to connect to
the Internet if you lose your settings or no longer
have the adapter. You can also use the Release and
Renew buttons to apply your WAN IP address to
the router. Press Release to clear the old IP address
and press Renew to request a new address from
your ISP.
