THE lights on a BT broadband router is your Wi-Fi’s way of telling you what’s wrong – so, they’re all helpful to know.
But the purple flashing light, in particular, is one you should always remember.
The purple light on your BT Hub means the Wi-Fi isn’t working as it should.
The purple light will flash when the router is working but isn’t connected to the internet.
This is the case for select Hubs, including the BT Smart Hub, BT Smart Hub 2 and Ultrafast Smart Hub.
