Clark has noticed that the cost of wireless networking systems for the home has gotten dirt cheap. More than 50 percent of us now use high-speed connections, and many more people now have more than one computer. So the need for wireless networks has increased. It’s neat and simple to do. The only problem is if you live in an apartment, condo or a neighborhood where home are close together, your neighbors can tap into your network and use your Internet access. They either use your network to get online for free, or they can burglarize the information on your computer. It might not be a big deal if you don’t have much on your computer. But if you have financial information or other confidential information on there, you don’t want people tapping into your network. It’s very easy to set up. All you have to do is set up a password on your wireless account. So, be careful!
