Over 4.5m broadband customers exposed to security risks due to outdated Wi-Fi routers
More than 4.5m households* may be exposed to broadband security risks and poor performance due to outdated Wi-Fi routers.
According to research by MoneySuperMarket**, 16% of broadband customers have a router that is over five years old.
Most of us get our WiFi routers through our internet service providers (ISPs) when we sign up for a broadband package, but unless we have switched to a new deal or required a repair, few of us realise that using an old router can put your network at risk and slow down our connection.
“Wireless routers are the sort of home appliance that most people will set up and forget about,” said Alicia Hempsted, finance expert at MoneySuperMarket.
“But using an old router can be risky because it might not get important firmware updates to fix security problems. This makes it easier for hackers to break into your network and steal your information. What's more, older routers often lack the advanced security features found in newer models, such as improved encryption standards and enhanced firewall protection.
“To ensure your home network remains secure, it's important that you keep your router updated and consider upgrading to a new router if yours is more than five years old."
How old is too old for your router?
Routers older than five years are often considered outdated, as they may lack the latest security features and advanced encryption standards, but routers as young as three years might need replacing if they haven't been properly maintained and kept up to date.
But even if you have taken good care of your broadband router, like most products they have a lifecycle. If your router is nearing the end of its lifecycle, it may no longer receive updates from the manufacturer. Without these updates, any new vulnerabilities pose a significant threat to your network.
Hackers are frequently finding exploits in our tech security and becoming more sophisticated in their methods to get their hands on your data.
Manufacturers regularly release patches to fix these issues, but they will need to be installed for your router to stay protected to stay protected. So, if your old router has stopped receiving these important updates, it may be time to retire it and get a new one.

How can I tell if my router is out of date?
If you are unsure about the age of your tech, there are signs to watch out for to know if your router is out of date.
Check if your router still receives regular firmware updates from the manufacturer (you can usually find this in the router's settings online or on the app). If updates have stopped, your router may be vulnerable to new security threats.
Performance issues, such as frequent connection drops or slow speeds, can also indicate that the hardware is aging and less reliable. Performing broadband speed tests is one way to check on the performance of your router and the quality of your internet service.
Modern routers come with advanced security features like WPA3 encryption and built-in firewalls, which older models may not support.
Check the manufacturer's website for information on your router model; if it's listed as end-of-life or no longer supported, it's time to consider a new one.
How to keep your current router up to date
Check regularly for firmware updates:
Most modern routers have an option to automatically check for updates. You can usually find this in the router's settings, accessible via a web browser or a dedicated app.
Change default passwords:
Ensure you change the default administrator password to something strong and unique. This prevents unauthorised access to your router's settings.
Monitor connected devices:
Regularly check which devices are connected to your network. This helps you spot any devices that you don’t recognise that might be using your WiFi.
Enable security features:
Make sure your router's security features, such as WPA3 encryption and firewalls, are enabled. These features provide an additional layer of protection against cyber threats.
Consult your Internet Service Provider (ISP):
If you're unsure about how to update your router or enable certain features, contact your Internet Service Provider (ISP) for assistance.
They can provide guidance and support to ensure your router is secure.
If your router is outdated, you can request an upgrade from your ISP. They might provide a new router as part of your contract, especially if you're experiencing performance issues.
