OfficeConnect Wireless Cable/DSL Gateway

The OfficeConnect Wireless Cable/DSL Gateway is designed to provide a cost-effective means of sharing a single broadband Internet connection amongst several wired and wireless computers. The Gateway also provides protection in the form of an electronic “firewall,” preventing anyone outside of your network from seeing your files or damaging your computers.

As you can see in the example in Figure 1, 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.

Figure 1 Example Network Without a Wireless Cable/DSL Gateway

When you use the Wireless Cable/DSL Gateway in your network (Figure 2), it becomes your connection to the Internet. Connections can be made directly to the Gateway, or to an OfficeConnect Hub or Switch, expanding the number of computers you can have in your network.
