Summary
A secure home Wi-Fi network helps protect personal devices, private information, and internet access. Strong encryption, updated equipment, and careful router settings reduce the chance that nearby users can access or misuse a home network.
Why home Wi-Fi security matters
Your home Wi-Fi network connects many of your most personal devices, including phones, laptops, tablets, smart TVs, printers, cameras, speakers, and smart home devices. If a home network is poorly secured, someone nearby may be able to misuse the connection, observe unsafe traffic, or attempt to access devices on the network.
How Do Home Wi-Fi Networks Work?
Your Wi-Fi network is you home's wireless internet connection. It usually involves a wireless router that sends a signal through the air. Your personal devices use that signal to connect to the internet. Unless your home network is password protected, any device within range can connect to the signal and use your internet connection.
WPA3
WPA3 is the latest Wi-Fi security standard and provides stronger protection than previous options. If your router and devices support WPA3-Personal, it is generally the best choice for home Wi-Fi security. WPA3 includes improved encryption and protections against password guessing attacks.
Recommended when available
WPA2
WPA2 is still widely used and can be secure when configured with AES encryption and a strong password. If WPA3 is not available on your router or devices, WPA2-Personal with AES is the next best option. Avoid using WPA2 with TKIP or mixed mode if possible, as these are less secure.
Acceptable when configured correctly
Legacy security
Legacy security configurations include older standards like WEP, WPA-Personal with TKIP, and enterprise modes that may not be properly configured. These options are generally less secure and should be updated to WPA2 or WPA3 when possible.
Should be upgraded when possible
Open networks
Open networks have no visible encryption and are higher risk for home use. They can allow nearby users to connect without a password, potentially misuse the connection, or access devices on the network. Open Wi-Fi may be appropriate for public spaces with additional protections, but is generally not recommended for residential networks.
Not recommended for home networks
How to secure your home Wi-Fi network
Use this list as a basic idea of how to improve home network security. Refer to your own router user manual and provider's website to learn more about how to secure your Wi-Fi network.
- Use WPA3 if your router and devices support it.
- If WPA3 is not available, use WPA2-Personal with AES.
- Use a long, unique Wi-Fi password.
- Change the default router administrator password.
- Update your router firmware regularly.
- Disable Wifi Protected Setup (WPS), remote management, and Universal Plug and Play (UPnP) if you do use these features.
- Create a guest network for visitors and smart home devices.
- Replace old routers that no longer receive security updates, particularly ones that can only handle legacy firmware.
- Check to make sure the router firewall is turned on.
