BT MORADO-INTERMITENTE on Smart Hub: no internet, check broadband cable
Risk level
Low
Usually safe to check without specialist tools.
Urgency

What it means
BT links the Smart Hub 2 flashing purple light to a hub that works but does not reach the internet, and the first check it asks for is the broadband cable: black with grey ends, plugged in correctly, with a filter where one is needed. It also reminds you a newly switched line can take until midnight on activation day. The light does not say whether the cable, the socket or the line is at fault, and it does not prove the hub is faulty.
