Do you need a LAN?
If you have more than 1 computer, (PC, Mac, Xbox 360, etc,) at home or in an office you will want them to connect to the Internet. You will also probably want them to communicate with each other and share printers, etc. In order to do this, you will need to network them
Practically all computers these days come ‘network ready’ with network cards built in and the software (e.g. Windows on the PC or MAC OS on the Mac) is very user-friendly now, but it can still be very frustrating when is just doesn’t work.
This site shows you how to get the most out of your LAN and how to set it up first time with minimum fuss.
Just follow the guides to get started and ask in the forum if you need any help!
