Best Buy wi-fi routers and extenders

Routers and wi-fi extenders should offer a fast, reliable wi-fi signal that’s powerful enough to give coverage throughout even the largest houses. Scroll down for our exclusive list of Best Buy models.

Put us to the test

Our Test Labs compare features and prices on a range of products. Try Which? to unlock our reviews. You'll instantly be able to compare our test scores, so you can make sure you don't get stuck with a Don't Buy.

While many of us receive a free router from our internet service provider (ISP), you'll often get better speeds and improved performance by buying your own router. In our lab tests we directly compare the free models with third-party routers so you'll know whether it's worth shelling out on your own device.

We also compare a range of wi-fi extenders that help to rebroadcast the wireless signal from your router. These devices help ferry the wi-fi signal to all corners of your house, ensuring your connection doesn't drop out when streaming your favourite Netflix show.

The best routers and wi-fi extenders help you get the most out of your internet connection. They're fast enough that you won't experience any slowdown even if your whole family is online at the same time. And they're powerful enough that they can transmit their signal throughout even the biggest houses.

Our tests go further than anyone else's to ensure that the Best Buy routers and wi-fi extenders we recommend are the true cream of the crop. And we don't just reveal the best – if we come across any Don't Buy routers or wi-fi extenders that fail to make the grade, then we tell you about those too so that you don't end up with a dud.

How we uncover the best routers and wi-fi extenders

Every router and extender we review goes through a rigorous assessment. Our experts perform dozens of different checks and measurements. This enables us to directly compare all the latest models and to tell you just what you need to know about your next router or extender.

  • Speed and range You shouldn't have to sit next to your router to get online, so we test data transfer speeds on laptops at different distances from the router.
  • Ease of use Routers and wi-fi extenders can sometimes be tricky to set up, so we assess how easy it is to get each device out of the box and up and running.
  • Security We check router and wi-fi extender security, penalising models that don't make your network safe and stop others piggy-backing on your network as part of the default settings. We also look for child protection features to stop certain computers connecting to the internet after a set time.
