The lights on a BT Broadband Router are your WiFi’s way of telling you what’s wrong – so it helps to know them all.
But you should always keep an eye on the purple flashing light in particular.
What does a purple light on a BT Hub mean?
The purple light on your BT Hub means the WiFi is not working properly.
Why is my BT Hub flashing purple?
The purple light flashes when the router is working but not connected to the internet.
This is the case with select hubs including BT Smart Hub, BT Smart Hub 2 and Ultrafast Smart Hub.
How to fix a purple flashing light on a BT Hub?
Check that the broadband cable (the black one with the gray ends) is plugged in properly and that you are using a filter if necessary.
If your hub is new, chances are your broadband hasn’t been activated yet.
According to BT, the day your broadband is switched on it could be as late as midnight before it starts working again.
The network provider added that if you have fiber broadband and have just upgraded to the BT Smart Hub, your Openreach modem is no longer needed.
And if you try to use them together, your broadband won’t work.
If this is the case for you, simply plug your Smart Hub into your main phone wall socket.
Alternatively, you can use the My BT app or the company’s service status pages to check if there are WiFi issues in your area.
