If you are experiencing difficulties with your installation, try the following:
•
Ensure all networking equipment is switched on.
The Router
should be showing a green 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 green or 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 Router.
The Router
should be displaying a green or yellow 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 the Alert LED has stopped flashing.
The Alert LED may
continue to flash for one minute or longer during start up, depending on
your network configuration. Wait until the Router completes its self test
routine, and the Alert LED is off.
•
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.
•
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.
•
You cannot remember the Router IP address.
Run the Router
Discovery application from the CD-ROM. This will always connect you
to the Router.
Cable Internet Connections.
• Some Cable providers authenticate to the user’s computer MAC
address. If this is required, go to
Network Settings > Connection
to
ISP
and select
Dynamic IP address
as the
IP allocation mode.
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
Network Settings > Connection to ISP
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 is using PPPoE or PPTP, go to
Network Settings >
Connection to ISP
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
Network Settings > Connection to ISP
and enter the
PPPoE Service Name in the field provided. If it is not required, you
must leave it blank.
For further Problem Solving and Technical Support information,
refer to the Router User Guide, supplied in PDF format on the CD-ROM
that accompanies your Router.
PROBLEM SOLVING
Keeping Your Existing IP Configuration
If you don't want to change your IP infrastructure or have static IP addresses
the Discovery Application, found on the accompanying CD, can be used to
locate the Router. You can then use the Setup Wizard to set its IP parameters.
Refer to the User Guide for more details.
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 are
able to 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
Setup 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.
By default, 3Com recommends that you leave the LAN IP address for
the Router 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.
3Com recommends that you leave the DHCP Server at the default values,
unless you already have a DHCP Server on your network.
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 internet modem have been correctly configured.
Now that you have successfully configured your Router 3Com recommends,
as part of our continuous improvement process, you download the latest
firmware from the web at
www.3com.com
.
Refer to the Problem Solving section if you cannot make contact with the
Router or the Internet.
Connecting Additional Computers
You may now connect additional computers to the remaining 10/100 LAN
ports on the Router. Ensure that each computer you connect to the Router
has been configured as described in section 2. You should restart each
computer whilst it is connected to the Router before you try to use it to
access the Internet.

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:
IP Address, Subnet Mask, ISP Gateway Address, and DNS address(es).
4. PPTP (DSL or Cable)
PPTP is used by some providers, mostly in Europe. 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, and VPN Server address (usually
your modem).
You will be asked for the IP Allocation Mode when you run the Setup Wizard.
