Have you ever found your Wi-Fi doesn't cover your entire house? Maybe you want to stream Netflix in the bedroom, but it's out of the range of the router. Or you can't get online in the kitchen to read recipes without eating up valuable mobile data.
Help is at hand, in the form of BT Whole Home Wi-Fi.
It's a new Wi-Fi system that promises to cover every room in the house, all the way from the garage to the attic.
Now that more and more of our lives are online, it will be particularly useful for anyone with a big house, and a large family who all want online access in their separate rooms at the same time.
So what does it involve? And how do you get it? Read on for everything you need to know.

1 It comprises three discs
The system comprises three disc-shaped Wi-Fi repeaters. These are about the size of a small frisbee, and they extend the coverage area of your Wi-Fi network.
They're not Wi-Fi routers, but essentially amplifiers that spread the router's Wi-Fi signal further.
The idea is you place them around your home in order to maximise coverage. Because each acts independently, you're best off spreading them around the house as wide as they allow. That way, you'll maximise your Wi-Fi coverage.
Inside each is a dual-core CPU (the likes of which are usually found in smartphones), an Ethernet LAN port, and four built-in 2.4GHz and 5GHz antennas.
They're very clever, too. BT claims they combine to make an "intelligent self-configuring wireless network" that switches you to the fastest and most reliable signal as you move from room to room.
2 It's super fast
Make no mistake, this is a premium product. It works with dual-band AC2533 routers, which means they support both the 2.4GHz and 5GHz bands. In theory, these should give you speeds of up to 800Mbps and 1733Mbps respectively. Though in reality, real-world performance will be a little less than that.
Of course they won't make your broadband super speedy, as they can only work with the Wi-Fi signal you already have. But if you have superfast Wi-Fi, the system will be able to spread it around the house without compromising on speed.
3 It has its own app
You control the system through an app on your smartphone or tablet.
This lets you see who's online and how the network is being used, control how bright the discs shine – ideal for freaking out someone in their bedroom – and see vital diagnostic information about the network, like the current speeds you're getting and how much bandwidth each device is using.
It also lets you pause the home network to make sure everyone goes offline for a set period – dinnertime, say. And it advises you on where best to place the discs to maximise your Wi-Fi coverage throughout your home.
4 It automatically checks for software updates
The last thing you want is anyone compromising your network and using it to get online themselves.
Obviously as your network spreads, the chance of that happening increases. But BT has built-in a smart security system to see off ne'er-do-wells.
The Whole Home Wi-Fi System automatically runs software checks to make sure you've got the latest firmware and security updates.
If you do have a connection issue, you won't have to reboot it either. It checks itself, and automatically reboots should the connection drop.
5 It isn't cheap
As we said, this is a premium product, and as such commands a high price.
