A quick guide on fixing BT disc flashing red 

What is a Complete WiFi?

BT Complete Wi-Fi boosts broadband strength with a Wi-Fi "disk". 

Also, it's an impressive piece of kit on paper.

According to BT, it's compact, reliable, and guarantees flawless WiFi in each room of your home.

If you live in a house with four bedrooms, you can see up to a 25% speedup thanks to your one disk.

But here is the best part. BT is so confident in its claims that, for some reason, if you don't get a wireless connection throughout your house, they can send you two more discs to boost your signal for free.

How does it work?

It will work through a Wi-Fi Disk combination and BT's Smart Hub 2 to produce a complete 'mesh' network throughout your house. 

The disc connects to the hub with the strongest signal, and walking around the house increases the signal from the hub, greatly reducing the chances of hitting an uneven surface.

All of this, according to BT, can give you faster connections and the ability to stream HD content in the room.

Networks are treated as one entity, so you don't have to use many different passwords to connect to them.

You need the My BT app to find out where to place your discs for the best signal. 

Once downloaded, you can check each room's WiFi signal and see if any other devices are connected.

Who is it for?

It's aimed at people who have to put up with patchy WiFi spots at home.

However, you can only sign up and get the WiFi warranty if it is a BT Fiber Broadband customer using the Hub 2 router.

Full Wi-Fi discs are unavailable on Sky, Plusnet, EE, Virgin Media, or other popular carriers.

Customers of other providers can sign up for BT's equivalent services in the form of Whole Home Wi-Fi. 

This is similar, but without using the BT Smart Hub 2.

However, it's a good idea to check with your current provider first to see if there's a fix for poor connectivity before enabling the whole house Wi-Fi.

BT Complete Wi-Fi may suit BT Broadband customers living in large homes, cottages, or old townhouses.

How many should you need?

This depends mainly on the size of the house but also on factors, including the floor number and if the walls are particularly thick. 

However, one disk of him is sufficient for most properties.

Yet, if you have more than 3 or 5 bedrooms, you will likely need a second or third disc.

    Having some issues trying to connect my BT whole home wifi disks to my Vodafone router. When I plug the disk in to the router and follow the steps on the app the disk goes from a flashing blue to a static red and not connecting however, on the Vodafone broadband app it shows as a device connected to the network? I spoke to a chap on the phone yesterday regarding a different issue and he says they are just TP-Link repeaters branded as BT so they should be able to work with Vodafone.
    Is there something in the Vodafone settings I need to change in order to allow access or something? Wonder if any one else has had this problem?

      Hi, you can follow these steps:
      - Plug one end of the ethernet cable into a yellow port on the back of the Hub and the other end into the yellow port on the disc
      - The light on the Wi-Fi disc will start flashing blue and will turn solid blue after a couple of minutes
      - You can now unplug the cable. The light will change to flashing red, but will go back to solid blue after a few seconds
      - Unplug the disc from the mains and plug it in at the preferred location
