Wireless networking
Networking overview
A network is a collection of devices such as computers, printers, Ethernet hubs, wireless access points, and routers
connected together for communication through cables or through a wireless connection.
Devices on a wireless network use radio waves instead of cables to communicate with each other. For a device to
be able to communicate wirelessly, it must have a wireless print server attached or installed that enables it to receive
and transmit radio waves.
Common home network configurations
There are different ways a network can be set up. Some examples of common home network configurations are:
• Laptop and printer connected wirelessly with Internet
• Computer, laptop, and printer connected wirelessly with Internet
• Ethernet-connected devices with Internet
• Computer, laptop, and printer connected wirelessly without Internet
• Laptop connected wirelessly to printer without Internet
The computers and laptops in all five scenarios must be wired and/or have wireless network adapters built in or
installed in them so that they can communicate over a network.
The printers in the following diagrams represent Lexmark printers with Lexmark internal print servers built in or
installed in them so that they can communicate over a network. Lexmark internal print servers are devices made by
Lexmark to enable Lexmark printers to be connected to wired or wireless networks.
Scenario 1: Laptop and printer connected wirelessly with Internet
• A computer is connected to a wireless router by an Ethernet cable.
• A laptop and a printer are connected wirelessly to the router.
• The network is connected to the Internet through a DSL or a cable modem.
Scenario 2: Computer, laptop, and printer connected wirelessly with Internet
• A computer, a laptop, and a printer are connected wirelessly to a wireless router.
• The network is connected to the Internet through a DSL or a cable modem.
