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.
Wireless 11n
Cable/DSL Firewall
Router
The 3Com Wireless 11n Cable/DSL Firewall 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.

When you use the Router in your network (

), it becomes your
connection to the Internet. Connections can be made directly to the
Router, or to a 3Com Switch, expanding the number of computers you
can have in your network.
