How to Secure Your Home WiFi Router

How to Secure Your Home WiFi Router

Your router is the front door of your home network. Every phone, laptop, TV and camera in the house talks to the internet through it, so a weak setting there puts all of them at risk. The good news: securing it takes about 20 minutes and no special tools. This guide covers the settings that matter most, in order of importance.

The menu names differ between router makers, so look for similar wording in yours. Nothing here needs you to open the router or install software.

Before You Start: Open the Router Settings

1. Connect a computer or phone to your home Wi-Fi (or a network cable).
2. Find the router's address (usually something like 192.168.0.1 or 192.168.1.1). See how to find your router IP address on any device.
3. Type that address into a browser and sign in. Many newer routers use a phone app instead; the maker's name is on the label under the router.

Tip: write down the current Wi-Fi name and password before you change anything, so you can reconnect your devices if needed.

1. Change the Router's Admin Password

The admin password protects the settings page, not the Wi-Fi itself. Many routers ship with a default one printed on the label or published in the manual, which anyone on your network could look up.

• Look for Administration, System or Management > Password.
• Choose a long passphrase (four or more random words works well) that you don't use anywhere else.
• Keep it different from the Wi-Fi password.

2. Use WPA3 or WPA2 Encryption

In the Wireless or Wi-Fi security section:

• Choose WPA3-Personal if every device you own supports it.
• If older devices can't connect, choose WPA2/WPA3 (transition or mixed mode), or WPA2-Personal (AES).
• Avoid WEP, WPA and TKIP. They are outdated and Microsoft, among others, has deprecated them.

3. Set a Strong Wi-Fi Password

Anyone who has your Wi-Fi password can reach every device on your network. Use at least 12-16 characters, and change it if you've shared it widely over the years or if a former roommate or contractor still knows it.

After changing it, every device has to reconnect with the new password. If you forget what you saved, see how to find your WiFi password on Windows 11.

4. Update the Router Firmware

Firmware updates fix security holes that attackers actively look for.

• Look for Firmware update, Router update or Administration > Update.
• Turn on automatic updates if your router offers them.
• If the router has had no update for years and the maker lists it as end-of-life, replace it. An unsupported router stays vulnerable no matter how you configure it.

Don't unplug the router while an update is installing.

5. Turn Off WPS

WPS (Wi-Fi Protected Setup) lets devices join with a button press or an 8-digit PIN. The PIN method has known weaknesses. If you don't use WPS, turn it off under Wireless > WPS. You can still connect new devices by typing the password.

6. Turn Off Remote Management

Remote management (also called remote access, web access from WAN or cloud access) lets someone reach the settings page from the internet. Unless you really need to manage the router while away from home, turn it off. If you use the maker's app, check that its account has a strong password and two-step verification.

7. Turn Off UPnP If You Don't Need It

UPnP lets devices open ports on the router by themselves. Some game consoles and apps rely on it, so turning it off can cause problems with online gaming or video calls. If you don't need it, turning it off reduces what a compromised device on your network can do. If something stops working afterwards, turn it back on.

8. Use a Guest Network

Most routers can run a separate guest network. Use it for visitors and, if the router allows, for smart-home gadgets such as plugs, bulbs and cameras. Devices on the guest network can reach the internet but not your computers and phones.

9. Check What Is Connected

Open the Connected devices, Attached devices or DHCP clients list. If you see something you don't recognize, change the Wi-Fi password so every device has to reconnect with the new one.

What Not to Rely On

• Hiding the network name (SSID) doesn't stop anyone who wants to find it, and it can make your own devices connect less reliably.
• MAC address filtering is easy to get around and becomes a chore every time you get a new device.

Neither hurts, but neither replaces a strong password and current firmware.

Still Not Sure?

If a change leaves you without internet, restart the router and check the steps in router connected but no internet. As a last resort, most routers have a reset button that restores the factory settings, which also resets the admin and Wi-Fi passwords to the ones on the label, so you'd need to set everything up again.
