Five ways to make your home Wi-Fi safer

A few router settings can make a meaningful difference to the privacy and reliability of your home network.

Your router is the front door to your home network. Phones, laptops, televisions and smart devices all depend on it, so its default settings deserve a quick review.

1. Change the router administrator password

This is different from your Wi-Fi password. The administrator password controls the router settings page. Use a long, unique password and save it in a password manager. Never leave the manufacturer default in place.

2. Use WPA3 or WPA2 security

Open your router’s wireless security settings and choose WPA3-Personal when all your devices support it. WPA2-Personal is still widely used when WPA3 is unavailable. Avoid WEP and old WPA modes; they are no longer considered safe.

3. Install firmware updates

Router updates often fix security flaws and connection bugs. Check the router manufacturer’s app or settings page every few months. If automatic updates are available, enable them.

4. Create a guest network

A guest network is useful for visitors and for smart home devices that do not need to communicate with your computer. Give it a different password from your main Wi-Fi and turn off local-network access when the router offers that option.

5. Review connected devices

Most routers show a list of connected devices. Review it occasionally. An unfamiliar device is not always an intruder — it could be a phone with a generic name — but it is worth checking. Change the Wi-Fi password if you cannot identify it.

Where to place the router

Keep the router in an open, central location where possible. Thick walls, metal cabinets and being tucked behind a television can weaken the signal. Better placement can solve many apparent “internet problems” without buying new equipment.
