BT’s Complete Wi-Fi service gives you a guaranteed wi-fi signal in every room of your home, or £100 back.

At home, the strength of your wi-fi signal rapidly drops as you move away from the router. This means you might have poor wi-fi in parts of your home, leading to dropped connections, buffering and slow downloads.

In the UK, BT now offers Complete Wi-Fi as an optional add-on to all of their fibre broadband plans. It gives you a guaranteed wi-fi signal in every room of your home so you can work, learn, stream and game wherever you are. It does this using mesh networking technology to improve the wi-fi signal in your home.

In this article, we’ll review BT’s Complete Wi-Fi service. We’ll start by looking at how it works, how you can get it and the main benefits of using Complete Wi-Fi. We’ll also look at BT’s latest broadband offers and at the technical specifications of the Smart Hub 2 router and Complete Wi-Fi Disc. Finally, we’ll look at how you can change your broadband provider to BT.

What is BT Complete Wi-Fi?

For many people, a major frustration when using the internet at home is having a poor wi-fi signal in parts of your house. This leads to dropped connections, buffering when you’re watching videos online and downloads taking a long time. It can also worsen the battery life on mobile devices like your smartphone.

BT’s Complete Wi-Fi service is an add-on for BT Broadband that improves the Wi-Fi signal through your home. It uses a combination of BT’s Smart Hub 2 router and up to 3 Wi-Fi Discs that boost the signal from it. It does this using mesh networking technology so you’ll get one seamless wi-fi network with better overall speeds through your home.

The Complete Wi-Fi service is backed by BT’s Complete Wi-Fi Guarantee. This says you’ll be able to get a reliable wi-fi signal in every room of your home. If it isn’t possible, you’ll get £100 back from BT.

How To Get BT Complete Wi-Fi

To get BT’s Complete Wi-Fi service, start by choosing your BT Broadband plan online. At present, you can get BT’s fibre broadband service from £24.99 per month, with a range of special offers available like a £90 reward card on Fibre 2.

Once you’ve chosen your new BT Broadband plan, tap the button to “customise your package”. You’ll be given the option to add Complete Wi-Fi for an extra £12/month. You can also add BT TV and Hybrid Connect to your plan if you like.

You can add Complete Wi-Fi when ordering your broadband plan on BT’s website.

As an alternative to adding Complete Wi-Fi to your fibre broadband plan, you can also get it as part of BT’s Halo 3+ unbreakable home wi-fi service.

BT Complete Wi-Fi Features

Wi-Fi Coverage In Every Room

The Smart Hub 2 and Wi-Fi Disc work together to give you a single wi-fi network across your home.

The main benefit of having BT’s Complete Wi-Fi add-on is the ability to get a reliable Wi-Fi signal in every room of your home.

To enable this, BT will give you their latest Smart Hub 2 router along with one Wi-Fi Disc to get started. The Smart Hub 2 and Wi-Fi Disc work closely with each other to give you a stronger wi-fi signal that reaches every room.

Once you’re able to get a reliable wi-fi signal in every room of your home, you’ll be able to stay connected whichever room you’re in (for instance, allowing you to work from the attic or from a spare bedroom).

Fast & Seamless Home Wi-Fi

The Complete Wi-Fi service uses mesh networking networking to give you one seamless home wi-fi network. There’s no need to reconnect to different networks as you walk around your home: everything happens automatically in the background to give you the best performance.

Adding a Complete Wi-Fi Disc to your home wi-fi network should improve the overall speeds you get. According to BT, a typical four-bed home will see a 25% increase in wi-fi speeds when using a single Wi-Fi Disc. In many cases, the improvement can be even larger, especially if you’re currently suffering from poor wi-fi in certain places.

Because Complete Wi-Fi uses mesh networking technology, it’s very different from cheaper wi-fi range extenders and repeaters that you can buy on the high street. Older wi-fi range extenders and repeaters normally reduce the speeds available on your network by around 50%. You’ll also need to change wi-fi networks as you walk around your home (e.g. to manually switch between the wi-fi signal from your hub and the extender).

Complete Wi-Fi Guarantee

The Complete Wi-Fi Service is backed by BT’s Complete Wi-Fi Guarantee.

When you initially take out the service, you’ll get a Smart Hub 2 router and a single Wi-Fi Disc to get started. According to BT, one Wi-Fi disc should be enough to cover most homes. However, up to two further discs are available at no extra charge if you need them.

If, after the installation of three Wi-Fi Discs, you’re still unable to get reliable Wi-Fi in every room of your home, you’ll get a £100 credit applied to your bill. BT says you should be able to get a download speed of at least 10Mbps in every room of your home. This is more than enough for smooth HD-quality video streaming.

According to BT, the Complete Wi-Fi Guarantee “covers your main home” and “does not cover outbuildings, gardens or sheds”.

Hybrid Connect

If you have BT’s Hybrid Connect service, you can use Complete Wi-Fi together with it.

With Hybrid Connect, you’ll get a 4G-based backup broadband connection. If there’s ever a disruption to your fibre broadband service, it will automatically switch over to 4G, keeping you connected to the internet. This happens seamlessly and transparently at the hub so there’s no need to switch wi-fi networks or to sign in again on your devices.

If you’re using Complete Wi-Fi with Hybrid Connect, it will continue boosting your home wi-fi signal regardless of whether you’re connected using fibre or 4G. However, the Complete Wi-Fi Guarantee does not apply when you’re connected to 4G. This is because the speeds on the 4G network may be affected by external factors like 4G coverage or congestion.

Switching to BT Broadband

If you’re currently using another broadband provider, it’s easy switching your service to BT. This will allow you to take advantage of BT’s Complete Wi-Fi for a guaranteed Wi-Fi signal in every room of your home.

To begin the switch, start by ordering your new BT Broadband plan online. When you do this, you’ll be given the option to “customise your package” and to add Complete Wi-Fi to your plan.

Once you’ve completed the online order process, you’ll be given a date for your service to switch over. This will normally be in around 2-3 weeks time. In advance of the service going live, BT will send you a Smart Hub 2 router and a Complete Wi-Fi Disc. You’ll need to plug these in on the date that your BT service goes live.

For step-by-step instructions on how to switch to BT Broadband, please select your current provider from the drop-down menu below:

  • Richard Horton said:

    We have 3 extra dishes, each with “excellent” status but degradation due to thick walls means router speed of 150mb/s downgrades to 50 at point of use.
    My power line adaptors don’t work. They connect but give minimal speed.
    Power line would overcome the wall issues.
    How can I connect them or can you recommend adaptors that will work with BT hub?

    • Hi Fred,
      Thanks for your comment. There are three things you can do here:
      1. You can add Complete Wi-Fi to your broadband plan for an extra £10/month (a new contract will also apply when you get this). This will give you a Smart Hub 2 and up to 3 Wi-Fi Discs if required.
      2. You could order the individual items yourself from the BT website. It would cost you £400 for a Smart Hub 2 and 3 Complete Wi-Fi Discs.
      3. Alternatively, it’s worth considering other mesh wi-fi systems as well. For instance, BT’s Whole Home Wi-Fi system is available for £200 with 3 discs. This is probably a better option if you want to go down the do-it-yourself route.
      Hope this helps,
      Ken

  • Hello
    We have broadband from BT. Our SH 1 is located in a basement area and I don’t want to move it. At the moment the house is served by four wirless access points which are connected to the SH 1 by ethernet cables. Will the BT Complete Wifi system function as intended IF I connect the disc(s) to the new SH 2 via the existing ethernet cables? I ask because when Sky installed their Q box and (three) mini boxes they said that their mesh system would not function correctly if the mini boxes were connected to the router by ethernet cables.
    Thanks in advance.
    Michael
