Either you don't have a network at home, or your wired network is showing its age, and you need to build a wireless network yourself.

The first site you should visit is "Wireless Product Equipment - Network Routers, Access Points, Adapters and More". This site reveals exactly what hardware you need to buy and how it all works together.

You may also want to visit "DIY: Wireless network buying guide". This article first of all works out with you what type of network you need to build. Is this purely a home network, or are you building a network that you need to use at home and you also work with another network when you go to work? Maybe you want your network to be super-good for online gaming and entertainment? This article walks you through the ideal network for your circumstances.

The absolute best set of instructions for setting up a wireless network, without a doubt, is "Tech Guide: Setting up a Wi-Fi home network." These instructions span 12 pages of information complete with pictures where explanation can be made more informative.

I suggest you read all three sites, then go and purchase the hardware you need, and then following the set of instructions that seems to be the best that you can understand, read and build as you go. Do not try to build the network without reading the instructions. The devil is in the detail, and miss one little detail and you could be troubleshooting your network build for hours.

Really, following the ZDNet set of instructions you can be very successful in building the network first up!
