An unsecured wireless network leaves your home computers and your network open to people around you who may take advantage of your personal information. Anything you do on your wireless network may be seen by others who are also logged on to the network, unless you've properly secured the network and taken other security precautions.
When your wireless network is not secure, your neighbors can get onto your network and access the Internet from their computers. In addition to utilizing your connection for their own use, they can also view what is happening on your network. Your personal information can be easily compromised, because neighbors can view what sites you go to, what email you send and what your passwords are, so that they could gain access to your financial information.
Create a Password
Setting up a password to protect your wireless network is one way to deter neighbor from accessing your private information over the wireless internet. If you set up a password or security key, only people who know your password will be able to log onto your wireless. Ensure that your password is something that you'll remember, and something that would be difficult for your neighbors to guess.
Encryption makes it difficult for anyone to view what you're doing on your network, since it changes data into a code between the computer and a wireless router. Beyond encryption for the network itself, you can also encrypt specific files or folders on your computer to make them more secure and less likely to be viewed.
Reduce Connection Area
To avoid neighbors gaining access to your Wi-Fi, try to make the connection area smaller. If you currently have a wireless router near a window, the connection area may go far beyond that window so that a nearby house can pick up your signal. Move the router deeper into your own house to make the connection area more compact so that fewer people can access the signal.
