First you need a dual band Wi-Fi router. This is your "hub" if you like. All of your computers connect to it via RJ45 (Ethernet) or Wi-Fi, then this connects to to your phone line or fibre optic modem. In each computer you will need a Wi-Fi card or ethernet port. You can buy these in most electrical shops as with the router. The included CD will get you connected to your router. Remember to secure your network with WPA/WEP Encription or passers by will be able to connect to your network & hack into your computers. If you need any more help, post a question on my message board.
A dual band wireless router is the most modern type of router. It broadcasts over two bands, so it is faster and more reliable than a single band router.
A dual band wireless router is capable of transmitting and receiving signals in both the 2.4 GHz and 5 GHz radio bands. This ability was originally developed because the 802.11a and B wireless transmission standards used the 5 GHz band, while all subsequent standards switched to the 2.4 GHz band. A dual band wireless router is often used in business settings where the secure internal network uses the B standard, and other more general wireless services are provided with other standards.
Wireless routers can provide up to 12 MB/s if you are using 802.11n on the 5.4 GHz. band.
