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.
• 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 2 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.
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 Gateway'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.
• If you cannot remember the Gateway IP address. Run the
Gateway Discovery application from the CD-ROM. This will always
connect you to the Gateway.
Running the Configuration Wizard
1. If you haven’t already done so, restart your computer.
2. 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 are able to access the Login page, then your computer has
correctly received an IP address from the Gateway.
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. Refer to section 1 for details.
5. 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 :
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, 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.
Connecting Additional Computers
You may now connect additional computers to the remaining 10/100 LAN
ports on the Gateway. Ensure that each computer you connect to the
Gateway has been configured as described in section 2. You should restart
each computer whilst it is connected to the Gateway before you try to use it
to access the Internet.
