INTRODUCING THE ROUTER
Welcome to the world of networking with 3Com®. In the modern
business environment, communication and sharing information is crucial.
Computer networks have proved to be one of the fastest modes of
communication but, until recently, only large businesses could afford the
networking advantage. The OfficeConnect® product range from 3Com
has changed all this, bringing networks to the small office.
The products that compose the OfficeConnect range give you, the small
office user, the same power, flexibility, and protection that has been
available only to large corporations. Now, you can network the
computers in your office, connect them all to a single Internet outlet, and
harness the combined power of all of your computers.
OfficeConnect 11g
Cable/DSL Router
The OfficeConnect 11g Cable/DSL Router is designed to provide a
cost-effective means of sharing a single broadband Internet connection
amongst several wired and wireless computers. The Router also provides
protection in the form of an electronic “firewall” preventing anyone
outside of your network from seeing your files or damaging your
computers. The Router can also prevent your users from accessing Web
sites which you find unsuitable.
Figure 1 shows an example network without a Router. In this network,
only one computer is connected to the Internet. This computer must
always be powered on for the other computers on the network to access
the Internet.
12
CHAPTER 1: INTRODUCING THE ROUTER
Figure 1 Example Network Without a Router
When you use the Router in your network (Figure 2), it becomes your
connection to the Internet. Connections can be made directly to the
Router, or to an OfficeConnect Switch or Hub, expanding the number of
computers you can have in your network.

20
CHAPTER 2: HARDWARE INSTALLATION
When positioning your Router, ensure:
Using the Rubber
Feet
Wall Mounting
■
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. 3Com recommends you provide a minimum of
25 mm (1 in.) clearance.
Use the four self-adhesive rubber feet to prevent your Router from
moving around on your desk or when stacking with other flat top
OfficeConnect units. Only stick the feet to the marked areas at each
corner of the underside of your Router.
There are two slots on the underside of the Router that can be used for
wall mounting.
When wall mounting the unit, ensure that it is within reach of the power
outlet.
You will need two suitable screws to wall mount the unit. To do this:
1 Ensure that the wall you use is smooth, flat, dry and sturdy and make two
screw holes which are 150 mm (5.9 in.) apart.
2 Fix the screws into the wall, leaving their heads 3 mm (0.12 in.) clear of
the wall surface.
3 Remove any connections to the unit and locate it over the screw heads.
When in line, gently push the unit on to the wall and move it downwards
to secure.
When making connections, be careful not to push the unit up and off the
wall.
CAUTION: Only wall mount single units, do not wall mount stacked
units.
Before you Install your Router
Before you Install
your Router
21
Before you install and configure your Router, you need the following
additional information. If you do not have this information, contact your
Internet Service Provider (ISP). Space is provided below for you to record
this information.
If you have a DSL connection and your ISP allocates IP information
dynamically over PPPoE, you need a User Name and Password:
PPPoE User Name
: ______________________
PPPoE Password
: ______________________
PPPoE Service Name
: ______________________
If you have a DSL connection and your ISP allocates IP information
dynamically over PPTP, you need a User Name, Password and PPTP Server
Address:
PPTP User Name
: ______________________
PPTP Password
: ______________________
PPTP Server Address
: ____.____.____.____
You only need a PPPoE Service Name if your ISP requires one. Do not
enter anything if your ISP does not require this information.

22
CHAPTER 2: HARDWARE INSTALLATION
If your ISP allocates IP information dynamically over a protocol other than
PPPoE, you do not need any further information. This configuration is
typical of cable connections.
Powering Up the
Router
To power up the Router:
1 Plug the power adapter into the power adapter socket located on the
back panel of the Router.
2 Plug the power adapter into a standard electrical wall socket.
Connecting the

lose contact with the Router if you change the wireless configuration.
To communicate wirelessly with your Router, your wireless NIC should be
set as follows:
■
Encryption — none
■
Service Area Name/SSID — 3Com
■
Channel — 11
24
CHAPTER 2: HARDWARE INSTALLATION

Selecting Clear Channel Select allows the Router to automatically select
an available channel when first powered on.
The Service Area Name default for 3Com products is “3Com”. Up to 32
(case sensitive) characters can be entered for the Service Area Name.
3Com strongly recommends that you change the SSID to something
other than the default.
If you are configuring the Router from a wireless computer any changes
you make to the wireless configuration will result in communication
between the Router and your computer being lost. This is why 3Com
strongly recommends that you configure the Router from a wired
computer.
It is very important that you set up your wireless clients to use the same
Service Area Name or SSID as the one you use on this screen. If your
clients use a different Service Area Name then they will not be able to
communicate with the Router.
The choice of channel is less important as Clients will generally search all
of the available channels. You should however make a note of the
40
CHAPTER 4: RUNNING THE SETUP WIZARD
channel you select as this may be useful if you experience problems with
your clients.

of the client’s network card. Clients that have fixed addresses will get
the same IP address each time they connect.
Check the box to fix an association. Uncheck the box to remove the
fixed association.
As you connect more devices, the client list will grow to a maximum
number of 253 clients.
The release button allows the lease time for the IP address that has been
issued to a device to be cleared. The lease time is set at 12 hours. If a PC
has been switched off, using the Release button would allow the 12 hour
lease time to be cleared. The IP address would then be available for
another device if there were no other IP addresses available.
Adding Fixed DHCP Mappings
You can add Fixed Mappings so that the Router allocates an IP address
chosen by you when it encounters a particular device.
You only need to create Fixed Mappings for devices that need a specific IP
address. For devices that do not need a specific IP address, the Router will
automatically allocate addresses.
To add a Fixed Mapping:

Figure 32 Configuration Screen
Enable Wireless Networking
Allows you to enable/disable the wireless section of your LAN. When
disabled, no wireless PCs can gain access to either the Internet or other
PCs on your Wired or Wireless LAN through this Router.
Channel Selection
The Channel Selector allows you to specify which Channel the Router will
transmit and receive on. If another access point or Router nearby is using
the same Channel as you, there will be a reduction in the performance of
your network. If this seems to be the case, you should select a different
channel number. Usually the Wireless computers will scan to find the
correct channel, but if they don't you must configure them to use the
same Channel number as the Router.
48
CHAPTER 5: ROUTER CONFIGURATION
Choose the Clear Channel Select option to automatically choose the
clearest channel. The Router will check for the clearest channel whenever
it is rebooted, powered up, and when the Clear Channel Select option is
first applied.
Valid channels are country dependent. See “Channels” on page 119 for a
list of channels approved by each country.
Service Area Name/SSID
This allows you to name your Wireless network. The field will accept any
alphanumeric string and has a maximum length of 32 characters. Your
Wireless computers must be configured with exactly the same name or
you will not establish a connection. The Service Area Name may also be
referred to as “ESSID” depending on your networking vendor. By default
the Router uses the name “3Com”. 3Com recommends that you change
the default name.
In order that your wireless computers can connect to the Router, you
must:
■
Use Infrastructure Mode not Adhoc Mode.
■
Have the same Service Area Name as the Router.
■
Have the same Channel number as the Router.
■
Use the same encryption type and keys as the Router.
■
Ensure that the PC is included in the authorized Wireless PCs list if
Connection Control is enabled. See page 53.
Enable Broadcast SSID
This feature can be used to improve the security of your wireless network.
When the tickbox is checked, the Router will broadcast the Service Area
Name/SSID of your wireless network. This will allow unauthorized clients
from detecting your SSID and attempting to connect to your network.
If you have a wireless client that can detect all the available SSIDs in your
area, your client will not list the Router SSID unless this feature is enabled.
The clients will still be able to connect, provided that they are supplied
with the SSID.
3Com recommends that you install your wireless network with this
feature enabled and then disable it once you have set up the Router and
wireless clients.
Wireless Settings
Encryption
49
When setting up wireless networks, it is important to remember that with
encryption disabled, anyone with a Wireless PC can eavesdrop on your
network. 3Com recommends that you get the network working with
encryption disabled first and then enable it as the last step. This will
simplify setting up your network.
The Router supports two types of encryption:
■
WPA — Wi-Fi Protected Access (WPA) is a 256 bit encryption method
with keys that change over time.
■
WEP — Wireless Equivalent Privacy (WEP) is a 64 bit or 128 bit
encryption method with user configurable fixed keys.
WPA provides a higher level of security, provided by its longer key and
dynamic changes made to the key over time. 3Com recommends that
you use WPA with any clients which support it.
If you enable encryption on the Router, you must reconfigure your
wireless PCs to use exactly the same Encryption Type and Keys otherwise
the devices will not understand each other.
The encryption methods used by the Router secure data transmitted
through wireless communications between the Router and its wireless
clients. Enabling encryption has no security effect on data transmitted
through wired (Ethernet) connections or through your connections to the
Internet.
Configuring WPA
Encryption
The only configuration that is needed for WPA is to enter the pre-shared
key. This key is used to start the dialog between the Router and the client.
During this dialog, a new key is agreed, making it more difficult to
eavesdrop on wireless networks encrypted using WPA, than those
encrypted using WEP. The pre-shared key can be entered as a 256 bit
series of hexadecimal digits or as a pass-phrase.
50
CHAPTER 5: ROUTER CONFIGURATION
Figure 33 Encryption Keys Screen showing WPA configuration
To enter the pre-shared key as hexadecimal digits:
1 Select Enabled - Manual Pre-shared Key from the WPA Encryption Type
drop-down box.
2 Enter a pair of hexadecimal digits in each of the 32 Key fields. Each field
can contain a hexadecimal number from 00 to ff, for example 1a.
3 Click Apply to generate the key.
To enter the pre-shared key as a pass-phrase:
1 Select Enabled - Pre-Shared Passphrase from the WPA Encryption Type
drop-down box.
2 Enter a phrase of between 8 and 63 characters in length in the
Passphrase field. This passphrase will be used to generate a 256 bit key.
3 Click Apply to generate the key.
Configuring WEP
Encryption
There are two levels of WEP encryption available, 64 bit (sometimes
referred to as 40 bit) and 128 bit. Use the WEP Encryption Type box to
select the desired level.
Wireless Settings
51
Encryption Keys
Figure 34 Encryption Keys Screen showing WEP configuration
A Key is a hexadecimal (0-9, A-F) number used to encrypt and decrypt the
data. There can be up to 4 keys and each key can be as long as 26 digits.
The Router also offers a number of methods for converting plain text into
hex keys. The text is much easier to remember than hex keys but it relies
on your wireless adapters also supporting this feature. Different
manufacturers have developed different ways of converting plain text
and so interoperability is not guaranteed. If you are experiencing
difficulty, the Manual Hex Key method is supported by most vendors.
There are four methods available to generate the encryption keys:
■
Manual Key Entry - This method allows you to manually enter hex
keys. Virtually all manufacturers support this scheme. Enter a two digit
hexadecimal number in every box. Hexadecimal numbers are formed
from 0-9 and A-F.
■
3Com Encryption String - This method is supported by 3Com Wireless
products. The string can contain any alphanumeric characters and
must be between 6 and 30 characters long. A single string will
automatically generate 4 unique keys for 64 or 128 bit WEP.
■
ASCII - This method is supported by some adapter cards running
under Windows XP. The string must be exactly 5 characters for 64 bit
52
CHAPTER 5: ROUTER CONFIGURATION
WEP and 13 characters for 128 bit WEP. You must enter a separate
string for each of the 4 Keys. You can leave a string blank provided
this Key is not selected as the Active Transmit Key.
■
Passphrase - This is another common method and similar to the 3Com
Encryption string. In 64 bit WEP, the passphrase will generate 4
different keys. However, in 128 bit WEP, this method only generates 1
key which is replicated for all 4 keys. The passphrase can be up to 31
characters long and may contain any alphanumeric characters.
Select the key generation method you wish to use from the drop down
list. If you have other wireless products choose the scheme that is
compatible with these, then enter the appropriate information.
If you encounter any difficulty when you enable WEP ensure that you
check that each key on your wireless computer is exactly the same as
each key on your Router. In other words, Key number 1 on the Wireless
computer must have the same Hex number as Key number 1 on the
Router, Key 2 on the Wireless computer must match Key 2 on the Router
and so on.
The Active Transmit Key selects which of the 4 Keys the Router uses when
it transmits. You can change the selected key periodically to increase the
security of your network.
Some wireless adapters have only one key available on their WEP
configuration page. If this is the case ensure it is the same as Key 1 on the
Router and that it is selected as the active transmit key.

Profile
Figure 39 Profile Screen
56
CHAPTER 5: ROUTER CONFIGURATION
Some 3Com Wireless Network Adapters allow you to import Wireless
configurations via a ‘profile’. The Router can generate a profile so that
you do not need to configure your Wireless PCs manually.
The profile contains three items as follows:
■
Service Area Name/SSID of the Router
This is configured on the Configuration tab under the Wireless
Settings option.
■
Encryption settings from the Router
This is configured on the Encryption tab under the Wireless Settings
option.
■
Profile Name
This is used to identify the profile once it has been imported into the
Wireless Network Adapter configuration software.
To set up a profile (once the Service Area Name/SSID and Encryption
settings have been configured in the Router):
1 Enter a Profile Name (up to 25 alphanumeric characters) and then click
Save Profile.
2 Your browser will then prompt you to enter a file name and folder
location in which to save the profile. Once the profile has been saved it
can be copied on to another PC and imported into the 3Com Wireless
Network Adapter.
For instructions on how to import a profile, refer to the User Guide that
accompanies your 3Com Wireless Network Adapter(s).
If, once the profile is imported, the Wireless Network Adapter cannot
connect to the Router, check that:
■
the adapter is within range of the Router
if Connection Control has been enabled in the Router, the MAC address
of the Wireless Network Adapter must be included in the list of
authorized Wireless PCs.
Internet Settings
Internet Settings

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 can allocate IP information, as described below:
1 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
■
DNS address(es)
2 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.
3 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. To configure the
Router you will need to know the following:
■
Username
■
Password
■
Service Name (if required by your ISP)
When you install the Router, you will not need to use the PPPoE software
on your PC.
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. To configure
the Router you will need to know the following:
■
Username
■
Password
■
VPN Server address (usually your modem)
58
CHAPTER 5: ROUTER CONFIGURATION
When you install the Router, you will not need to use the dialup VPN on
your PC anymore.
