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,

8
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.
