3. Enable Wi-Fi encryption
You wouldn't let a criminal waltz into your home, but that's exactly what you're doing if you leave your home Wi-Fi network unsecured. Not only are you inviting a crook to use your internet for illegal activities, they can snoop on your gadgets to find out what you're doing.
That can give them your passwords, surfing habits or even let them slip a virus onto your machines. This is why I tell you to be careful when using public Wi-Fi.
So don't let your home network be a public Wi-Fi hotspot. Here's how to make sure it's secure against hackers. You should also know how to check it occasionally for unauthorized users.
