About nine out of every 10 adults use the Internet in the U.S. and more than 75 percent of all American households use Wi-Fi as their primary network connection.

Wi-Fi is everywhere. It’s in our workplaces, grocery stores and homes. It allows us to connect with people all over the world. It’s how most business is conducted and how many families communicate.

Unfortunately, not all Wi-Fi is secure. If a network is compromised, personal and financial data stored on computing devices is at risk of being stolen.

To help prevent cyber criminals from accessing your network, we’ve outlined some common ways your home Wi-Fi can be hacked, as well as security measures you can take to keep your Internet safe.

1. Default Pre-Settings

When you set up your home’s Wi-Fi, did you change the default settings?

A default name, or service set identifier (SSID), and IP password is provided with new routers. Default passwords are often widely known and simple to crack. Change the SSID and router password once your Internet is installed. Consider a long, complicated strand of numbers and symbols to increase password security.

2. Unsecure Internet of Things (IoT) Devices

Any Internet of Things (IoT) device that connects to a network can be hacked. From smart locks to security cameras, your connected devices could give cyber criminals an opportunity to access your Wi-Fi and steal your information. Secure your connected home devices with these cyber security practices:

3. Outdated Firmware

Hackers are always looking to exploit network flaws—especially when it comes to firmware.

Firmware is the software built in a piece of hardware, like your router, that tells it how to operate. Just like passwords and connected devices, firmware must be regularly updated. When updates are neglected, flaws are discovered and hackers take over your network.

Updating firmware depends on the make of the router. We recommend checking for firmware updates every three months.

Safe Wi-Fi Practices

Take your Wi-Fi security a step further and follow these safety practices.

  • Invest in reliable antivirus, anti-spyware and firewall software to add an additional layer of protection against outside access.
  • Visit and download content only from secure websites and only open emails from sources that you know and trust. Hackers can often gain access to your network and devices through phishing links in this way.
  • Contact your router manufacturer or wireless Internet provider if you are concerned about your home Internet network at any time.
