1 BEFORE YOU INSTALL YOUR GATEWAY
2 PREPARING YOUR GATEWAY FOR USE
Before you install and configure your Gateway, you need the following additional information. If you do not have this information, contact your Internet Service Provider. Space is provided below for you to record this information.
If your ISP allocates IP information dynamically over PPPoE, you need your User Name and Password:
PPPoE User Name
PPPoE Password
If your ISP allocates fixed or static IP information, you need the following information:
IP Address | _______._______._______._______. |
|
|
Subnet Mask | _______._______._______._______. |
|
|
Default Gateway address | _______._______._______._______. |
|
|
DNS address | _______._______._______._______. |
|
|
|
|
Note: If your ISP allocates IP information dynamically over a protocol other then PPPoE, you do not need any further information.
PPPoE Client Software
If you have PPPoE client software installed on your computer, you will need to disable it. To do this:
1.From the Windows Start menu, select Settings > Control Panel.
2.Double click on Internet Options.
3.Select the Connections Tab. A screen similar to Figure 1 should be displayed.
4.Select the Never Dial a Connection option.
You may wish to remove the PPPoE client software from your computer to free resources, as it is not required for use with the Gateway.

Connecting Your Gateway
1.Connect the power adapter to the Gateway and wait for the Alert LED to stop flashing.
2.Ensure that your modem and computer are both switched on.
3.Use the supplied cable to connect the Gateway's Ethernet Cable/DSL port to the modem. Check that the Cable/DSL Status LED lights.
4.Connect your computer to one of the 10/100 LAN ports on the Gateway. Check that the LAN Port Status LED lights.
Refer to Figure 7 for an example configuration.
Running the Configuration Wizard
1.Insert the Gateway
Note: Discovery will find the Gateway even if it is unconfigured or misconfigured.
2.When the Welcome screen is displayed click on Next and wait until the application discovers the Gateways connected to your LAN.
3.Figure 2 shows an example Discovered Devices screen. Highlight the Cable/DSL Gateway by clicking on it, and press Next.
4.Click on Finish to launch a web browser and display the login page for the Gateway.
5.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.
6.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. Refer to section 1 for details.
7.By default, 3Com recommends that you leave the LAN IP address for the Gateway as 192.168.1.1. However, if you should choose to change it, make a note of the new address :
Gateway's LAN IP Address | _______._______._______._______. |
|
|
|
|
8.When the DHCP Server Settings page is displayed, make sure that the Enable the DHCP Server with the following settings option is selected.

3 CHANGING YOUR NETWORK’S CONFIGURATION
PROBLEM SOLVING
Once the Wizard has completed, the Gateway is ready for use. Before you can use it to access the Internet, you may need to make some changes to the configuration of your computers depending on how they are set up. As a minimum you must ensure that your computers are configured to obtain an IP address automatically.
To do this on Windows 95, 98 and ME
1.From the Windows Start Menu, select Settings > Control Panel.
2.Double click on Network. Select the TCP/IP item for your network card as shown in figure 5 and click on Properties.
Your existing
Cable/DSLInternet
Modem
If you are experiencing difficulties with your installation, try the following:
• Ensure all networking equipment is switched on. The Gateway |
should be showing a green Power LED. If it is not, check the power |
adapter connection. Do not use any power adapter with your |
Gateway other than the one supplied. |
To do this on Windows 2000
1.From the Windows Start Menu, select Settings > Control Panel.
2.Double click on Network and
3.Double click on Local Area Connection.
4.Click on Properties.
5.A screen similar to Figure 3 should be displayed. Select Internet Protocol TCP/IP and click on Properties.
6.Ensure that the options Obtain an IP Address automatically, and Obtain DNS servers automatically are both selected as shown in figure 4. Click OK.
7.Restart your computer.
3.In the TCP/IP dialog, select the IP Address
tab, and ensure that Obtain IP address automatically is selected as shown in figure 6.
Click OK.
4.Restart your computer.

Cable/DSL Gateway
• Ensure the Cable/DSL Modem is connected. The Gateway |
should be displaying a yellow 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 Gateway. The |
Gateway should be displaying a green or yellow LAN Status LED. If |
it is not, check that the computer is connected to one of the |
Gateway's LAN ports with an Ethernet cable. |
• Ensure your computer is configured correctly. Make sure that the |
computer obtains an IP address automatically. See Section 3 for |
details. Ensure that the NIC card is configured for autonegotiation. |
• Ensure that you do not have a web proxy enabled on your |
computer. Go to the Control Panel and click on Internet Options. |

Accessing the Internet
Launch your web browser and attempt to contact the Gateway by typing the following URL in the location bar: http://192.168.1.1, (if you changed the IP address, use the address you allocated.) If you are able to access the Login page, then your computer has correctly received an IP address from the Gateway.
Finally, attempt to browse to an Internet web site, such as www.3com.com. If you can successfully access this site, then your computer, Gateway and internet modem have been correctly configured.
Refer to the Problem Solving section if you cannot make contact with the Gateway or the Internet.

a different IP address, use that instead. Ensure that you include the |
http:// prefix. |
• If you cannot remember the Gateway IP address. Run the |
Gateway Discovery application from the |
