Extend your wi-fi for free: how to turn an old router into an access point

At Which? Tech Support, we regularly hear from members who struggle with unreliable wi-fi at home. But did you know that an old router you have lying around could potentially come to the rescue?

By plugging in a once-retired router and making tweaks in its settings, you can repurpose the device as a wi-fi extender. Doing so is a sustainable, money-saving alternative to buying a brand new one.

Below, our experts run you through the steps. We've also got details on how we uncover the very best wi-fi routers and extenders in our lab tests.

Each month, we feature one of the most popular questions answered by our Tech Support team.

Question of the month: can an old router boost my wi-fi signal?

'The wi-fi signal in my home office is very weak and the current cost of living has halted my plans for a mesh system. Is there a way I can use an old router to help the signal?'

Our expert says:

'Absolutely, and there are a few different ways to achieve this. Many routers come with a built-in 'wireless repeater' or 'wireless bridging' mode that lets you configure the router. Here, we’ll be covering how you adjust your settings to do this. It will work for the vast majority of routers released in the past five to 10 years.

'Not only will the router extend your wi-fi signal, but the ethernet LAN ports on the device can also used to physically connect other devices to your network.'

Put your old router to work in 6 steps

To get started, factory reset your old router. The exact method will vary, but usually this is done by pressing the reset button on the back of the router for 30 seconds.

Make a note of the IP addresses of your current router and the old one – these can be found on the back or on a small card from your broadband provider.

Once you've reset your old router, follow these steps:

With the technical steps out of the way, it's time to position your router where you have a weak signal. Use an ethernet cable to connect the old router to the main router, as it provides optimal performance and gives a reliable and efficient link between the two devices.
