You are now getting good speeds for BT IPStream that you are now on. However:
Not quite up to my previous 2.2mb download 0.78mb (haven't had that since Easter time) upload but it's a lot better.
Are these connection speeds or speedtests? Not that it matters here, as IPStream UP Sync is always 448 Kbps and before Easter you got higher.
Therefore, I suspect that Orange have moved you from LLU to BT IPStream, as they are doing for all its users since they have contracted with BT to take over their BB.

say about your exchange? Post its link.
Also, what are your full router stats now? You omitted Noise Margins last time.
