Ethernet Port Connect the LAN cable here.

■ In AP mode or Router mode, this is

connected to the LAN or WAN (Cable/DSL
modem).

■ In Client mode, this is connected to your

PC.

Power Connect the supplied power adapter here.

Modes Your 3Com OfficeConnect Wireless 54Mbps 11g Travel Router has four

modes:

■ Setup/Configuration Mode — used for configuration only.

■ AP (Access Point) Mode.

■ Router Mode

■ Client Mode — Allows a device with an Ethernet port to connect to a

wireless network.

The mode is set ONLY by the mode selector switch on the side of the
Travel Router. (You will need to wait a few seconds after changing
modes.)

It is important to understand these different modes, and the benefits of
each.

Setup/Configuration Mode

Use this mode to perform initial configuration of the Travel Router or to
perform any required configuration changes. In Setup/Configuration
mode, the following settings are always used.

User name admin

Password The current password is used. Default password is blank.

IP address 192.168.0.1 (Mask: 255.255.255.0)

DHCP Server Enabled (for both Ethernet & Wireless)

SSID 3Com is the default name.

Wireless Security Disabled

You can connect to the Travel Router using either the Wireless interface
or the wired Ethernet connection.

See the later section Initial Configuration for details.

Router Mode

In Router Mode, the Travel Router acts as a DHCP Server, allocating IP
addresses for Wireless stations (clients). It also acts as a Wireless NAT
Router with SPI/Firewall, sharing the IP address on the Ethernet
(LAN/WAN) port with all W ireless clients. (It has 2 IP addresses, one on the
LAN/WAN port and another on the Wireless LAN.)

When Should I use Router Mode? Use Router mode in any of these
situations:

■ The Ethernet port is connected to a Broadband modem rather than an

Ethernet port.

■ You want the wireless clients to be protected by the Travel Router's

SPI/Firewall.

■ You want the Travel Router to function as a DHCP server for the

Wireless clients.

■ You want the wireless clients to be in a separate network from the

network connected to the Ethernet port.

■ You have permission for ONLY ONE (1) user to connect to the LAN or

WAN, but you need to connect multiple users. (In Router mode, the IP
address on the Ethernet port is shared by all Wireless clients.)

When Should I NOT use Router Mode? You can always use Router
mode to establish a wireless connection to the LAN or WAN.

However, this mode uses a technology called NAPT (Network Address
Port Translation), and NAPT may cause problems with some complex
multi-user communication applications. (There is no problem with

4

common services such as HTTP, FTP, E-mail, etc.) If you have problems, you
should try getting permission for all users to connect to the LAN/WAN, so
you can use AP mode instead.

You can connect to the Travel Router, and change its configuration, while
it is Router Mode.

The IP address used is the Wireless LAN IP address, which can be set on
the Router setup screen. The default value is 192.168.0.1 (the same as
the Setup/Configuration Mode IP address), but you can change this if you
wish.

You MUST change the Wireless LAN IP address if the LAN/WAN is using
the address range 192.168.0.1 - 192.168.0.254.

Access Point Mode

In Access Point mode, the Travel Router connects Wireless stations to
each other, and to the LAN on the Ethernet port. Because the Travel
Router is transparent (does not have an IP address) you cannot configure
it while in AP mode.

When Should I use Access Point (AP) Mode? Use AP mode in any of
these situations:

■ There are multiple wireless clients, and you have explicit permission for

all users to connect to the LAN or WAN to which the Ethernet port is
connected.

■ You want the wireless clients to use a DHCP server on the network the

Ethernet port is connected to.
