gazaai, are you on Plusnet?
I was previously on BT then just switched to plusnet two days ago, hopefully my 76mb will be activated soon. You can see my previous banding on myDSLWebStats under my username: GaZaai
Edit:
Reading through the posts you seem confused to what I mean.
While I was on the 76mb package with BT I got banded at 66999 on the downstream, I was going to change ISP Provider anyway after my contract was up so I decided I would try going to plusnets 38mb package then upgrade to 76mb again a few days later to see if it removes the 66999 banding, just an experiment.
I will find out by tomorrow what happens...
