Everything...

Cables, filters, router, different PC. Took out all the originals and replaced with spares which i had. Exactly the same results i'm afraid.

Thanks for taking a look at the stats.

Since the initial drop, the sync speed has crept up a small amount. If the problem which caused the drop in sync in the first place was only temporary, am i likely to see the sync speed increase over time?

I noticed that it has gone from 5706 to 6062. Would i be right in saying that the IP Profile will start to increase automatically over time if it sees a stable line?

Sync speed is negotiated at sync time, if the interference isn't there at the time it'll sync faster. If it comes along later it may trigger a resync to a lower speed.

It won't "creep up" but you may see step changes if the SNR margin target adjusts based on stability.

Your graphs need to cover a longer time period - can you set it up to run for 24 hours with 30 second samples. An 80 minute snapshot is not really sufficient.

You can create a single graph with SNR and Sync speed together.

It was in last paragraph of the report

We were unable to identify any performance problem with your service at this time.
It is possible that any problem you are currently, or had previously experienced may have been caused by traffic congestion on the Internet or by the server you were accessing responding slowly.

Well, For whatever reason i decided to reset my router this afternoon...

When it re-sync'd this is what i was met with:

ADSL Link Downstream Upstream
Connection Speed 13707 kbps 959 kbps
Line Attenuation 24.0 db 10.7 db
Noise Margin 6.3 db 6.6 db

Downloads are pretty slow at the moment, but its normally like this late afternoon. Ill test it later when its quieter to see if its working at full speed.

I have done nothing whatsoever to get the increase in speed! Can only assume that it was something that BT has done, or as suggested something electrical was causing the problem somewhere in the vicinity.

Hope i am not counting my chickens too soon!

Well, that was short lived. Back down to 5106k.
