Im Following post with interest as mine is doing exactly the same as of today. It was working perfectly.
Mine went solid red and is now flashing green after rebooting. I suspect it's some sort of authentication error at BT's end, you would hope that someone at BT is already on the case so I'll give it 24 hours or so (it'll take that long to find someone who can do something about it anyway).
Mine doing the same. It was solid red. On reboot/reset it is now fast flashing green. Something's been done at the server end and they've not mentioned it!
