It wasn't all that long ago when personal computers where restricted for offices and wealthy households. Moreover, computer networks where approximately unheard of in residential settings, such technology was reserved for large office structure - things however, have progressed considerably over the years.
One of the most tasteless methods to share a broadband connection within homes and offices today is using wireless technologies.

Although such technology has revolutionised the way habitancy can way networks and the internet it does have a major disadvantage, one that was not prevalent with coaxial cables or the more familiar Cat5 network cable; this being security.
The technology that comprises a wireless network ordinarily consists of a wireless router; wireless receivers (generally Usb dongles or built in antennas); and in some cases one or more repeaters (if the signal needs to span an exceptionally long distance).
Once set up, the wireless router will happily start broadcasting and accepting facts within a obvious radius. This essentially means that your next door neighbour (or whatever in range!) could be accessing your network, and leaching your internet connection - which as well as invading your privacy could be costing you money if you have a broadband usage allowance.
So, the first line of defence is to familiarise yourself with your network and your routers configuration options, which are ordinarily accessed via a browser window
Router manufactures tend to apply the same Ssid (the networks name) and login details for all of their routers, so to begin with, changing these to something more personal is the first line of defence.
Following this you should apply some form of encryption, the favorite choice being Wep (Wired Equivalent Privacy) and Wpa (Wi-Fi Protected Access), the later of which is the most secure. This involves applying a exact "key" that any computer attempting to way your router will need to input.
Lastly, maybe one of the best ways to ensure only devices of your choice have way to your router is to build Mac filtering. Mac or Media way control is a unique code given to every physical network device.
Therefore, looking out the Mac code for each gadget in your network (this can prove difficult to the untrained so referring to the manufactures hand-operated is recommended) and inputting only these addresses on your Mac filter list will ensure only they will have access.
