Your home router is the doorway between your internet connection and the phones, computers, televisions, cameras, printers, smart-home devices, and other equipment in your house. Fortunately, you do not need advanced networking knowledge to make a home Wi-Fi network significantly safer.
The most important steps are protecting the router's administrator account, using modern Wi-Fi encryption, installing updates, and knowing which devices are connected.
What are the most important home Wi-Fi security settings?
For most households, focus first on a strong router administrator password, WPA3 or WPA2 encryption, a strong Wi-Fi password, current firmware, and disabling remote-management features you do not use.
1. Understand the two passwords
Your router may have an administrator password used to change router settings and a Wi-Fi password used by devices joining the network. They protect different things and should both be strong.
2. Change the router administrator password
Do not leave the administrator account protected by a factory-default or easily guessed password. Use a strong unique password that you do not reuse for email, banking, or other important accounts.
Access router settings only through the manufacturer's instructions, your internet provider's official app, or another trusted method.
3. Use WPA3 or WPA2 Wi-Fi security
When your equipment supports it, use WPA3. WPA2 remains common and can still provide appropriate protection for many home networks. Avoid older WEP security.
If changing the setting causes an older device to stop connecting, check whether the router offers a compatible WPA2/WPA3 mode before weakening security across the entire network.
4. Choose a strong Wi-Fi password
Use a long password or passphrase that is difficult to guess. Do not reuse an important account password. You can share a Wi-Fi password with trusted household members without giving them your router administrator password.
5. Keep the router updated
Router manufacturers release firmware updates to fix bugs and security problems. Turn on automatic updates when the router supports them. Otherwise, periodically check for updates through the router's normal administration interface or official provider app.
Do not download router firmware from an unfamiliar website.
6. Create a guest network when useful
A guest network lets visitors use your internet connection without giving them the password to the main household network. Some households also use a separate network for smart-home devices when their router supports it.
7. Review connected devices
Most routers or internet-provider apps show devices connected to the network. Names can be confusing, so an unfamiliar entry does not automatically mean an intruder is present. Compare device names and addresses with equipment in your home before taking action.
8. Disable features you do not need
If you do not use remote router administration, turn it off. Review other convenience features offered by the router and disable unnecessary access from outside your home network.
9. Protect the account associated with your internet provider
If your provider uses an online account or mobile app to manage the router, protect that account with a unique password and two-factor authentication when available.
10. Know what a VPN does—and does not do
A VPN can encrypt internet traffic between your device and the VPN service and can be useful for privacy in certain situations. It does not replace a secure router, strong Wi-Fi encryption, router updates, strong passwords, or careful browsing. Treat a VPN as an additional layer, not the foundation of home-network security.
Your 30-second home Wi-Fi check
- Is the router administrator password strong and unique?
- Is Wi-Fi using WPA3 or WPA2?
- Is the Wi-Fi password strong?
- Are router updates current or automatic?
- Do I recognize the devices connected to the network?
- Is unnecessary remote administration turned off?
What if you think someone is using your Wi-Fi?
Change the Wi-Fi password and reconnect your own devices. Change the router administrator password as well if there is any chance it was exposed. Review connected devices, install router updates, and verify that important settings have not been changed.
What if you cannot access the router settings?
Use the instructions from the router manufacturer or your internet provider. If the router was supplied by the provider, its support team may be able to help. Avoid following login instructions from unsolicited pop-ups or phone calls.
Should you hide your Wi-Fi network name?
Hiding the network name is not a substitute for strong encryption and passwords. Prioritize WPA3/WPA2, strong credentials, and updates rather than relying on the network being difficult to see.
What not to do
- Do not reuse an important account password for Wi-Fi.
- Do not leave the administrator password at a factory default.
- Do not use WEP when modern security is available.
- Do not download router updates from unofficial websites.
- Do not assume a VPN fixes insecure router settings.
How do you know you are safer?
Your router settings should require a strong administrator password, your Wi-Fi should use modern encryption and a strong password, updates should be current, and you should have a reasonable understanding of which devices are connected.
The Know Phishing takeaway
Protect the router settings, use WPA3 or WPA2, choose strong passwords, install updates, turn off access you do not need, and occasionally check what is connected. Those basic steps provide most households with a strong foundation.
