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.)

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.

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.

The plot thickens. Attainable is now 82488. I want my banding removed!

Banding is often due to too many disconnections.

Not in my case, my connection is normally solid for weeks on end.

Do you monitor it using MDWS?
