For the last few months my interleaving has increased as has the error rate mainly on the upstream.
Before I came to talk talk I was almost always on fast path with BT etc, but I suppose with Talktalk selecting a more stable setting I can expect some interleaving.
My max attainable sync usually stays around 90mbits/s downstream and 25-30 upstream but with Talktalk's error correction and interleaving my connection is usually in the high 60 to 70mbit/s.
I have tried changing routers a couple of times but to no effect.
Interleaving of 298 and RSCorrectable errors on the upstream from 5 to 300% is new.
Downstream interleaving is 1277 and even when my connection has been up for over a month without a disconnection it has stuck here.
The Downstream RSCorr is fine at well below 1% - 0.0278% just now.
The upstream correction and interleaving are what's really troubling and yes I use gigabit Lan cables for all testing and monitoring.
Hi @Murph_2 too advanced a question for me to answer so your post has been flagged for assistance and you should hear during tomorrow.
Yes, slow downs and periods of no activity which I take it are due to the huge number of retransmissions on the upstream path. As I say I never had interleaving on the upstream path until fairly recently (probably in over 6 years at least) and now the RSCorr/RS error rate sometimes shoots up to a few hundred percent instead of the sub 1% I'd expect.
Apologies for this.
We are unable to change the profile, this is set/changed by Openreach's DLM.
Please can you run a speed test when you experience this issue using a wired connection (and with no other devices in use) so we can see the results?
