Positioning Your Router
POSITIONING YOUR ROUTER
When positioning your Router, ensure:
• The unit is centrally located to the wireless computers that will connect to
the Router. A suitable location might be on top of a high shelf or similar
furniture to optimise wireless connections to computers in both horizontal
and vertical directions, allowing coverage throughout.
• In order to meet FCC radiation exposure regulations the Router should be
located in a position that maintains a minimum distance of 20 cm (8 inches)
from any personnel (refer to the User Guide for details).
• It is out of direct sunlight and away from sources of heat.
• Cabling is away from power lines, fluorescent lighting fixtures, and
sources of electrical noise such as radios, transmitters and broadband
amplifiers.
• Water or moisture cannot enter the case of the unit.
• Air flow around the unit and through the vents in the side of the case is
not restricted. We recommend you provide a minimum of 25 mm (1 in.)
clearance.

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 infor-
mation. 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 Router Address, and DNS address (es).
For computers using 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.
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.

Running the Setup Wizard
GB
4. PPTP (DSL or Cable)
PPTP is only used by some European providers. If the installation instruc-
tions 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 hange 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.
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.
