System Requirements

Before starting, you must ensure the following:

•You already have a cable or DSL broadband connection to the Internet with a suitable modem and that

this connection works properly. The modem must have an Ethernet port for connection to your Router.

•You have a computer that has an Ethernet connection available and is already correctly configured for

communication with the Internet. Your computer must be able to connect to the Internet via the

modem, and must have a Web browser installed.

•There are no other DHCP server devices on your local network that are responsible for allocating IP

addresses to your computers and other network-connected devices. Your Router will now perform this

function by default.

If one or more of these conditions are not met, refer to the comprehensive Router User Guide provided on

the accompanying CD-ROM for further guidance.

ABOUT YOUR ROUTER

The front panel of the router contains a series of indicator lights (LEDs) that help describe the state of

various networking and connection operations.

1. Power LED (Illuminated Logo) White

Indicates that the Router is powered on. If this LED is off, the power adapter or the connections to the

power adapter may be faulty. Refer to the Problem Solving section.

2. Alert LED Amber

Indicates a number of different conditions, as described below.

Off - The Router is operating normally.

Flashing quickly - Indicates one of the following conditions:

•The Router has just been started up and is running a self-test routine, or

•The administrator has invoked the Reset to Factory Defaults command, or

•The system software is in the process of being upgraded

In each of these cases, wait until the Router has completed the current operation and the Alert LED is

Off.

On for 2 seconds, and then off - The Router has detected and prevented a hacker from attacking your

network from the Internet.

Continuously on - A fault has been detected with your Router during the start-up process. Refer to

the main User Guide.

3. Cable/DSL Status LED Blue

Indicates that the internet connection to the Cable/DSL modem is active. If the LED is flashing, data is

being transmitted or received by the modem.

4. Wireless LAN (WiFi) Status LED Blue

If the LED is on it indicates that wireless networking is enabled. If the LED is flashing, data is being

transmitted or received. If the LED is off, the Wireless LAN has been disabled in the Router, or there is

a problem.

Refer to the ‘Problem Solving’ section.

5. Four LAN Status LEDs Blue

If the LED is on, the link between the port and the next piece of network equipment is OK. If the LED

is flashing, the link is OK and data is being transmitted or received. If the LED is off, nothing is

connected, the connected device is switched off, or there is a problem with the connection (refer the

‘Problem Solving’ section). The port will automatically adjust to the correct speed and duplex.

6. WPS LED Blue

When flashing indicates that the WPS function is active. The WPS function will operate for

approximately 2 minutes after the WPS mode has been activated.

The rear panel of the Router contains one WPS button, four LAN ports, one WAN port, one WiFi button, a

reset button and a power adapter socket

3. ISP CONNECTION METHODS

Before you can configure the Router you need to know the IP information allocation method used by your

ISP. There are four different ways that ISPs allocate IP information, as described below:

1. Dynamic IP Address (DSL or Cable)

Dynamic IP addressing (or DHCP) automatically assigns the Router IP information. This method is

popular with Cable providers. This method is also used if your modem has a built in DHCP server.

2. PPPoE (DSL only)

If the installation instructions that accompany your modem ask you to install a PPPoE client on your

PC then select this option. Note that when you install the Router, you will not need to use the PPPoE

software on your PC. To configure the Router you will need to know the following: Username,

Password, and Service Name (if required by your ISP).

3. Static IP Address (DSL or Cable)

The ISP provides the IP addressing information for you to enter manually. To configure the Router you

will need to know the following:

4. PPTP (DSL or Cable)

PPTP is only used by some European providers. If the installation instructions that accompany your

modem ask you to setup a dialup connection using a PPTP VPN tunnel then select this option. Note

that when you install the Router, you will not need to use the dialup VPN on your PC anymore. To

configure the Router you will need to know the following: Username, Password, Service Name (if

required by your ISP), and VPN Server address (usually your modem).

You will be asked for the IP Allocation Mode when you run the Setup Wizard.

4. RUNNING THE SETUP WIZARD

1. If you haven’t already done so, restart your computer.

2. Launch your web browser and attempt to contact the Router by typing the following URL in the

location bar: http://192.168.1.1. If you can access the Login page, then your computer has correctly

received an IP address from the Router.

3. Login using the default password admin. The Wizard will attempt to launch automatically, but if it

fails, select the Wizard tab and click on the Wizard button.

4. Where possible, the Wizard will recommend settings for most parameters. However, there are some

settings which you must provide. Most of these will have been provided to you by your ISP when you

set the account up.

5. 3Com recommends that you leave the LAN IP address for the router at the factory set default address

of 192.168.1.1. However, if you should choose to change it; make a note of the new address:

6. When the DHCP Server Settings page is displayed, make sure that the Enable the DHCP Server with

the following settings option is selected.

Connecting to the Internet

When the Wizard has completed, attempt to browse to an Internet web site, such as www.3com.com. If

you can successfully access this site, then your computer, Router and Cable/DSL modem have been

correctly configured. Refer to the Problem Solving section if you cannot make contact with the Router or

the Internet.

5. CONNECTING TO THE WIRELESS LAN

1. After you have configured the Router via the wired computer, you can connect to the Router via a

wireless computer.

The Router and wireless clients must have both the same SSID and the same encryption settings. All

wireless clients must use Infrastructure mode.

The default wireless settings for the Router are:

2. If you do not have a Wireless LAN you can use the Router’s default settings. Ensure that your wireless

clients have the default SSID, channel and encryption as detailed above.

If you have an existing Wireless LAN, configure the Router to use the same SSID and encryption

settings to be compatible with your existing wireless network.

3. If your computer has both a wired and wireless NIC installed, you must ensure that only one NIC is

used to communicate with the LAN. To use the wireless NIC, unplug the Ethernet cable and reboot

your computer.

4. Launch your web browser and attempt to browse to an internet web site such as www.3com.com.

If you can successfully access this site, then your wireless computer, Router and Cable/DSL modem

have been successfully configured.

5. 3Com strongly recommends that you enable WPA encryption to improve the security of your wireless

network and you change the SSID to something other than the default. Consult the on line help or

the User Guide for details.

PROBLEM SOLVING

If you are experiencing difficulties with your installation, try the following:

•Ensure all networking equipment is switched on. The Router should be showing a white Power

LED. If it is not, check the power adapter connection. Do not use any power adapter with your Router

other than the one supplied.

•Ensure the Cable/DSL Modem is connected. The Router should be displaying a blue Cable/DSL

Status LED. If no LED is displayed, check that your modem is switched on and that it is connected to

the Cable/DSL port with an Ethernet cable.

•Ensure that the computer is connected to the Router. The Router should be displaying a blue LAN

Status LED. If it is not, check that the computer is connected to one of the Router's LAN ports with an

Ethernet cable.

•Ensure that you do not have a web proxy enabled on your computer. Go to the Control Panel

and click on Internet Options. Select the Connections tab and click on the LAN Settings button at the

bottom. Make sure that the Use Proxy Server option is unchecked.

•If you are unable to access the Router's Web interface. Launch a web browser and enter

http://192.168.1.1. If you chose a different IP address, use that instead. Ensure that you include the

http:// prefix.

•Ensure your power adapter is correctly fitted. If the illuminated logo is not lit, check your power

adapter connections. Ensure the adapter is correctly inserted in to the power socket. Try an alternative

outlet. Check that the power cable connecting the power supply to the Router is not damaged, and

that the connector is correctly inserted into the Router. If the problem persists, it is likely that the

power adapter is faulty. Please contact 3Com for a replacement adapter.

Cable Internet Connections

•Some Cable providers authenticate to the user’s computer MAC address. If this is required, go to

Internet Settings and select Clone the MAC Address. This will copy the MAC address of your computer

onto the Internet port of the Router.

•Some Cable providers authenticate to the user’s Host Name. If this is required, go to Internet Settings

and enter the host name of your computer into the Host Name field.

DSL Internet Connections

•If you have an existing DSL line and have PPPoE or PPTP client software installed on your computer, you

will need to disable it. See section 2.

•If your DSL line uses PPPoE or PPTP, go to Internet Settings and ensure that the correct IP Allocation

mode is selected. Check that your Username and Password are correct.

•Some DSL providers require the use of a PPPoE Service Name. If this is required, go to Internet Settings

and enter the PPPoE Service Name in the field provided. If it is not required, you must leave it blank.

Wireless Configuration

•If you are unable to access the wireless LAN:

•Ensure that the wireless client is set to infrastructure mode.

•If you have a wired and wireless NIC in the same computer, ensure that the wired NIC is disabled. See

section 5 for details.

•Ensure that the Service Area Name (SSID) is the same for the wireless client and the Router.

•Ensure that the Router WiFi LED is on. If not, go to the Wireless Settings menu and enable Wireless

Networking, or press the WiFi button for 3 seconds until the WiFi LED is illuminated.

•Ensure that encryption settings are the same for the wireless client and the Router. If there are

problems, turn wireless encryption off in the client and the Router until you have established a wireless

connection.
