Safety tips for using Wi-Fi


If you have a laptop computer with wireless connectivity, you can access the Internet using Wi-Fi, or wireless networks, often in public places such as coffee shops, airports, hotels, and other spaces.
Here are four quick tips to enjoy the convenience of public Wi-Fi and help to protect your privacy.

1. Use a firewall

If your computer uses Windows Vista or Windows XP and you've installed Service Pack 2, you have a built-in firewall that's turned on by default.
You can configure Windows Firewall to provide better protection when you're using a public wireless network.

2. Hide your files

When you use public Wi-Fi, network encryption is often out of your control.
Check the privacy statement on the network's Web site to learn about the type of encryption they use. (If they don't have a privacy statement, you'd be better off not using the network.)
If you keep personal or financial information on your computer, consider investing in an operating system, such as Windows Vista, that includes the tools to protect your information through encryption.
