I have just spent ages speaking to BT CS to try and get the DLM reset. After a long drawn out convo, the gist of it was:
MY estimated line speed is up to 54Mbps (I've been connected at 61Mbps-ish for over a year)
She did another line reset (nothing after 15 mins so asked her to try again)
Then she told me she has requested another reset but said it might take 5-6 hrs, after which time, I need to reset the hub using the reset button!!
At that point, I asked her to make a not of what she said she'd done as I know I'll be back onto her later. She sent me a text to reply to and she will ring me back later if need be.
I can see this becoming a looooong drawn out affair
