How to Secure Your Home Wi-Fi Router in 10 Minutes
Your router connects every device in your home to the internet. If it's poorly secured, neighbours can use your internet, and attackers could snoop on traffic or change settings. Securing it takes only a few minutes.
Log into your router
The router's address and default login are usually on a sticker on the router, often 192.168.0.1 or 192.168.1.1. Type the address in a browser on a connected device. Some routers use a mobile app. See changing your Wi-Fi password for detailed login steps.
1. Change the admin password
The admin password controls the router's settings. Default passwords like "admin" are widely known. Change it to a strong, unique password.
2. Use WPA2 or WPA3
In Wireless Security settings, choose WPA3 or WPA2-PSK (AES). Never use WEP or "Open".
3. Use a strong Wi-Fi password
At least 12 characters. A passphrase of random words works well.
4. Turn off WPS
WPS (Wi-Fi Protected Setup) PIN mode has known weaknesses. Turn it off if you don't use it.
5. Update firmware
Check for firmware updates in the router's settings or app. Enable automatic updates if available. Very old routers that no longer get updates should be replaced.
6. Disable remote management
Unless you need it, turn off remote administration so the router can't be managed from the internet.
7. Change the network name
Change the default network name (SSID) to something that doesn't reveal the router brand or your identity, like your name or flat number.
8. Use a guest network
Give visitors and smart home gadgets a separate guest network, so they can't reach your laptops and phones.
9. Review connected devices
Check the device list and remove unknown ones. See removing unknown devices from Wi-Fi.
10. Consider turning off UPnP
UPnP lets devices open ports automatically. It's convenient for gaming but can be abused by malware. Turn it off unless you need it.
Securing smart home devices
Smart cameras, plugs, TVs and doorbells connect to your router too, and cheaper devices can be weak points:
- Change default passwords on every smart device and camera.
- Keep their apps and firmware updated.
- Put them on the guest network where possible.
- Buy from reputable brands that provide security updates.
- Turn off features you don't use, like remote access or cloud recording.
- Place indoor cameras thoughtfully and inform household members and guests.
Signs your router may be compromised
- Your router admin password no longer works.
- DNS settings changed to unknown servers.
- Websites redirect to strange pages or show unusual ads.
- Unknown devices keep reappearing.
If you notice these, reset the router to factory settings, update firmware immediately, and set it up again with new strong passwords.
When to replace your router
Replace your router if it no longer receives firmware updates, doesn't support WPA2 or WPA3, or struggles with the number of devices in your home. Modern routers are faster, more secure and often easier to manage through an app. See mesh vs extenders if coverage is also a problem.
Frequently asked questions
Should I hide my Wi-Fi network name?
Hiding the SSID adds little security and can cause connection problems. A strong password matters more.
My internet provider manages my router. Can I still change settings?
Usually you can change the Wi-Fi password and name. Ask your provider for admin access if needed.
