Introduction
This Guide takes you through the basic steps necessary to install and configure
your OfficeConnect ADSL Wireless 11g Firewall Router, and establish a connection
from your computers to the Internet. Throughout this guide the OfficeConnect
ADSL Wireless 11g Firewall Router is simply referred to as the Router.
Note: 3Com recommends that the Router is configured from a wired Ethernet
computer during the initial set-up.
Your package contains:
• One OfficeConnect ADSL Wireless 11g Firewall Router
• One 12V power adapter for use with the Router
• Four rubber feet
• One RJ11 cable
• One CD-ROM containing the User Guide
• This Installation Guide
• One Support and Safety Information Sheet
• One Warranty Flyer
System Requirements
Before starting, you must ensure the following:
• You already have an ADSL broadband account.
• You have a computer that has an Ethernet connection available and is
already correctly configured for communication with the Internet. Your
computer must be able to connect to the Internet via the modem, and must
have a Web browser installed.
• There are no other DHCP server devices on your local network that are
responsible for allocating IP addresses to your computers and other network-
connected devices. Your Router will now perform this function by default.
• If you require wireless access you have a computer with a wireless 802.11b
or 802.11g adapter card installed.
If one or more of these conditions are not met, refer to the comprehensive
Router User Guide provided on the accompanying CD-ROM for further guidance.
