THE lights on a BT broadband router is your device’s way of telling you what’s wrong.
The purple flashing light in particular is one that you should always remember.
What does a purple light mean on a BT Hub?
The purple light on your BT Hub means the Wi-Fi isn’t working as it should do.
Why is my BT Hub flashing purple?
The purple light will flash when the router is working but isn’t connected to the internet.
This is the case for some Hubs, including the BT Smart Hub, BT Smart Hub 2 and Ultrafast Smart Hub.
How do you fix a purple flashing light on a BT Hub?
Check that the broadband – the black cable with the grey ends – is plugged in correctly and you’re using a filter if needed.
If your Hub is new, then it’s likely that your broadband hasn’t been activated just yet.
According to BT, it can take up until midnight on the day it switches your broadband on for it to start working.
The network provider added that if you have Fibre broadband and you’ve upgraded to the BT Smart Hub, your Openreach modem isn‘t needed anymore.
If you try to use them together, your broadband won’t work.
If that’s the case, simply plug your Smart Hub into your master phone socket.
Alternatively, you can use the My BT app or the company’s service status pages to check if there’s any Wi-Fi issues in your area.
