1 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.
OfficeConnect ADSL	The OfficeConnect ADSL Wireless11g Firewall Router is designed to
Wireless11g	provide a cost-effective means of sharing a single broadband Internet
Firewall Router	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.

	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.
