Most people log into the network on their devices once and never think about their connection again unless something goes wrong. However, there are some important steps you should take to protect yourself from cyber threats related to unsecured WiFi networks. They only take a few minutes and most need to be done only once. Some of those steps include enabling your router’s encryption, creating a guest WiFi network and using a strong password.
Continue reading to learn about the steps you can take to protect your home’s WiFi network.
1. Enable your router’s encryption and firewall
WiFi encryption protects your data from being intercepted by unauthorized users. Over the years, WiFi encryption protocols have improved significantly – WPA3 is currently the most secure standard available. If your router only supports WPA2, that’s still a good option. However, if neither WPA3 nor WPA2 is available, you should consider upgrading your router to ensure better protection.
To check or change your encryption settings, log into your Internet Service Provider’s (ISP) admin portal. Most modern routers also come with built-in firewalls, so while you’re in the settings, make sure the firewall is enabled for an added layer of security.
2. Create a strong WiFi password
Weak or default passwords are a common target for cybercriminals, especially those provided by your ISP, which can often be cracked easily using automated tools. To improve your security, you should replace the default WiFi password with a strong, unique one. You have two good options:
- A long, complex password (at least 16 characters with a mix of letters, numbers and symbols), or
- A secure passphrase, which is a series of random words (e.g., “Disease8-Determine-Curve-Aloud-Exclaimed”) that’s easier to remember but still very strong if it’s long and unique.
It’s also important to change the router admin password, which is different from your WiFi password. The admin password is used to log into your router’s settings and manage your network. If this remains set to a default, anyone who gains access to your network could easily take control of your router.
If remembering complex passwords feels overwhelming, consider using a password manager. These tools securely store all your passwords and can generate strong, unique ones for every account. You only need to remember one master password to access your password vault.
3. Change the default network name
While updating your password, it’s also a good idea to change your router’s default network name, known as the Service Set Identifier (SSID). Leaving the default SSID makes your network an easier target for cybercriminals because it signals that basic security measures might be overlooked and it can reveal your ISP. This information can help cybercriminals identify specific vulnerabilities tied to your ISP’s equipment or default settings, making it easier for them to exploit your network.
To stay safer, choose a unique SSID that doesn’t include any personal or identifying information, such as your name or address. For example, instead of “SmithFamilyWiFi” or “Xfinity1234,” try something neutral and unrelated like “BlueSkyNetwork” or “SilentPenguin.”
4. Disable SSID broadcasting
When you open the WiFi options on your computer, you’ll often see a list of available networks, especially if you’ve lived in an apartment building, where dozens of network names appear. This list is made possible by something called SSID broadcasting, which allows your router to announce its network name to nearby devices.
For home networks, it’s a good idea to turn off SSID broadcasting so your network doesn’t show up publicly. This helps prevent neighbors or potential cybercriminals from easily spotting your WiFi and trying to access it. You can disable this feature in your router’s settings.
SSID broadcasting is useful in public places like airports or cafes, where networks need to be visible for users to connect. But at home, hiding your primary network adds an extra layer of security. If you use a guest network for visitors, it’s okay to keep that one visible for convenience, while keeping your main network hidden.
5. Set up a guest WiFi network
If you don’t already have a guest network set up, it’s a good idea to create one. A guest network is a separate, limited WiFi connection that lets visitors access the internet without giving them access to your primary network or any of your connected devices. This network has its own password, which should also be strong and unique.
While your visitors probably aren’t trying to cause harm, connecting unfamiliar devices to your main network can pose risks. Security is only as strong as the weakest link, and if a guest’s device has malware or weak security, it could compromise your network. Keeping your primary network password private and reserved for trusted users adds an extra layer of protection.
You can usually set up a guest network through your router’s settings or sometimes through your ISP’s admin portal, depending on the equipment and service you have.
6. Regularly update your router
Keeping your router’s firmware up to date is essential for protecting your WiFi network from attacks. As new cyber attack methods emerge and previously unknown vulnerabilities are discovered, router manufacturers release software patches to fix these security gaps. To stay protected, it’s important to download and install these updates promptly because delaying these updates can leave your network exposed to potential threats.
To check for updates, log into your router’s admin settings and look for a “Firmware Update” or “Router Update” section. Many modern routers also offer an option to enable automatic updates, so patches install in the background without you having to lift a finger. If your router doesn’t support this, it’s a good habit to manually check for updates every few months.
7. Use a VPN for further protection
A Virtual Private Network (VPN) encrypts your data when you’re connected to public WiFi networks like at a coffee shop or library, protecting your information from hackers and eavesdroppers. While using a VPN on a secured home network isn’t always necessary, some people choose to do so to prevent their ISP from tracking their online activities or to access geo-restricted content. If you’re comfortable with the potential trade-offs, such as slightly slower internet speeds, using a VPN at home can offer an extra layer of privacy and security.
Home security includes your network
Home security isn’t just about strong locks and alarm systems, your digital life needs protection too. With so many devices connected to your home network carrying sensitive information, securing your WiFi is essential to protect against cyber attacks and identity theft.

Frequently asked questions
How to secure a home WiFi router?
You can secure your home’s WiFi router by:
- Enabling WPA3 or WPA2 encryption
- Changing the default WiFi and admin passwords to strong, unique ones.
- Keeping your router’s firmware updated and enabling auto-updates if possible.
- Using a password manager like Keeper® to create, save and share your WiFi password.
- Enabling your router’s firewall for added protection.
- Setting up a guest network with a separate password for visitors.
- Changing the default network name (SSID) to something unique and non-identifying.
- Hiding your SSID to make your network less visible.
How do I make my WiFi private?
Two simple steps you can take to make your WiFi private include:
- Disabling SSID broadcasting: This prevents your network from showing up in WiFi lists.
- Using a generic network name: Avoid using a WiFi network name that includes your personal information.
You can take these steps by logging into your router’s settings.
How can a password manager help me secure my WiFi network?
A password manager enhances the security of your WiFi network in three key ways:
- It can generate a strong, complex WiFi password that’s difficult to guess or crack.
- The password is stored safely in an encrypted vault, so you never have to write it down or try to remember it.
- If you need to give someone access to your network, password managers like Keeper offer secure sharing features. With Keeper’s One-Time Share, you can send a WiFi password via an encrypted link that expires. This way, your network stays protected, even when you share access.
