Wi-Fi Security: How Secure Is Your Home Network?

Your wireless network is the gateway connecting phones, computers, smart TVs, cameras, game consoles and IoT devices to the internet. As the number of connected devices grows, keeping your network secure becomes increasingly important.

A strong Wi-Fi password is important, but it is only one part of network security. Encryption, router credentials, open ports, UPnP, connected devices and firmware updates all matter.

Perfect WiFi helps you review these important areas in one place.

What does a Wi-Fi security check look at?

1. Wi-Fi encryption

Modern networks should use a strong security standard such as WPA2 or, where supported, WPA3. Perfect WiFi can help you identify the current encryption level and highlight when your router settings deserve a closer look.

2. Default router credentials

Your router has separate administrator credentials for its management panel. Factory-default credentials can be predictable or publicly documented. Change the administrator password to a unique one as soon as possible — and keep it different from your Wi-Fi password.

3. Open router ports

Open ports may be required by games, cameras, servers or other applications. However, ports that are not needed can increase your network's attack surface. A detected open port does not automatically mean that your router has been compromised.

4. Unknown devices

Review the devices connected to your network. Phones, laptops, televisions, printers and smart home products may all appear in the router's client list. An unfamiliar device is not necessarily an intruder: technical device names and randomised MAC addresses can make familiar devices difficult to recognise.

5. UPnP

UPnP allows devices and applications to automatically request port mappings from the router. It can be convenient, but it also gives applications more control over network configuration. If you do not need UPnP, consider disabling it.

6. Guest network

A guest Wi-Fi network can separate visitors and less-trusted devices from your primary home network. It is especially useful if guests or IoT devices connect to your Wi-Fi regularly.

7. Wi-Fi password hygiene

Use a long, unique Wi-Fi password. Avoid names, addresses, birthdays, phone numbers, router names, simple character strings and passwords reused elsewhere.

8. Router firmware

Router manufacturers regularly release firmware updates containing security and stability fixes. Check for updates regularly and enable automatic updates when your router supports them.

How Perfect WiFi helps

Perfect WiFi presents important network-security checks in an easy-to-understand overview. Depending on the information available from your network, the app can help you review:

• Wi-Fi encryption
• default router credentials
• open ports
• devices on the network
• UPnP
• guest network availability
• Wi-Fi password hygiene
• router firmware status

Instead of hunting for every setting separately in your router's admin panel, you can start with one clear overview of the areas that matter most.

Wi-Fi security checklist

• WPA2 or WPA3 is enabled.
• The router administrator password is no longer the factory default.
• My Wi-Fi password is long and unique.
• I recognise the devices connected to my network.
• I have checked open ports.
• UPnP is disabled if I do not need it.
• A guest network is available when needed.
• My router firmware is up to date.

Frequently asked questions

How can I check whether my Wi-Fi is secure?

Review encryption, administrator credentials, Wi-Fi password strength, connected devices, open ports, UPnP and firmware. Perfect WiFi helps bring these checks together in one place.

Is WPA2 still secure?

WPA2 remains a widely used security standard. If your router and devices support WPA3, it is worth considering.

Does an unknown device mean someone hacked my Wi-Fi?

Not necessarily. Device names can be unclear, and modern phones often use randomised MAC addresses. Identify the device before assuming a security breach.

Should I disable UPnP?

Not always. UPnP is convenient for many apps and devices. If you do not need it, disabling it can reduce automatic port configuration.

Take care of your Wi-Fi security

A secure network doesn't have to mean a complicated setup. What matters most is regularly checking the basics and responding to potential issues.
