Home wireless routers allow you to connect your home computers together into a network. If you want to use your router as a firewall also, make sure you purchase one that has a built-in firewall. Otherwise, you can purchase a firewall separately. Wireless network routers will allow you to connect computers, notebook computers, PDAs and printers without wires. They are also useful for connecting laptops to the Internet and other networks, such as at work or at home. If you want to use a wireless network router, you need to have a wireless network adapter installed in any computer that you connect to your network. If these are not already in the computers, youll need to purchase them and add them in. To network your home computers to each other, you can use an access point instead, but we recommend routers because you can also use them for Internet sharing and firewall security. Also, home routers tend to be less expensive than access points.
