This type of network is gaining popularity because it is fairly cheap and easy to handle. It also allows you to go online no matter where you are. If you use a wireless network, make sure it is encrypted.
Follow the recommendations for protection
The most common practice is to connect a router directly to the Internet connection and, when you use wireless adapters on computers, to connect these adapters to the router. In this case, the wireless zone of the network may be considered part of the Internet. You should follow the recommendations for protecting your computer from attacks both from the Internet and from the wireless network zone in your home.
Encrypt internal networks
If you use a wireless network connecting several active computers in your home that share resources on the internal network, we recommend encrypting traffic on a wireless network if your network program allows this.
Use of public network access points
We recommend connecting only to access points that you trust. Access points may be bogus in order to retrieve personal information about you.
What can happen if you do not encrypt a wireless network?
As wireless networks are standard programs with a range that exceeds the walls of your home, someone outside your home can monitor traffic on your network and use your Internet connection via a portable computer. This is why it is always a good idea to encrypt traffic on a wireless network if your network program allows this.
