Massive jump in sync/obtainable

[link to this post]

Wow, at 0345 this morning, my attainable speed jumped to 81804 and sync to 66999 (I am banded and don't know how to get rid of that) - I have never had an attainable speed anywhere near that high. Is this, at last, the much-anticipated vectoring? (I already have G.INP.)

[re: kasg] [link to this post]

Well I had a re-sync at about 3:30, and some stats have changed a bit since Tuesday evening. The (Bearer 0) interleaving has dropped and the I, N and Q parameters changed. Upstream sync has risen, downstream almost unchanged. Attainable both up a bit, which for a night-time sync is interesting.

Compare with now:-

Thanks, interesting that it happened at about the same time. I don't know whether these before and after stats give any clues (they are legible if you zoom in).

Some of your details have moved in the opposite direction to mine. I think it's probably just routine DLM adjustments.

[re: RobertoS] [link to this post]

Well if so it's very unusual as this is by far the highest I have ever had. I'm still not sure whether that banding will ever go away of its own accord

Been getting weird things happening here, re-sync at about 3:45am a few days ago,sync at 78Mb & attainable was around 110Mb.Usually for my distance it's around 69-70Mb.
Same old pc, same old HG612 & Asus router, nothing different.
