I am however on the wrong upload profile of 50 Mb/s - I've read I should give it a couple of days before chasing BT as it can take a while for the right profile to kick-in. If I'm not on the proper profile by Monday I'll post on the BT Forums as theres an on-going thread there where the BT folks get it sorted for people.
Unplug your router from the WAN when you're done using it for today, do a factory reset and then turn it off. Plug the WAN back in when you get up tomorrow and power it back on, see if that clears the profile issue.
