I had the SR102 (the black one) on immediately after the line changes and that was pretty much the same around a 2.4mb down and maybe 1.1 up at a push. that is one of the reasons I switched in the asus to see more details around the connection and whether it was just a dodgy aging router.
irrespective of the routers deficiencies shouldn't DLM be trying to take the router to the target snr of 6ish? it doesn't seem to move from the low to mid 30s even through there are no crcs and no dropouts (apart from what I assume is the cabinet at around 5am every morning?)
Hope that helps. I could try the old router again?
The downstream 1997Kbps and extremely high noise margin suggest to me the line has been banded at 2Mbps downstream. That being the case it needs stability before DLM will relent and reduce the severity of the banding.
If setting to Annex B as I suggested in my previous post doesn't produce an improvement in 3-4 days I suggest that you do replace the ASUS with the SR102 then leave well alone for at least a month.
When the engineer worked on the line they should have requested a DLM reset . Whether that could be requested by Sky based on the fact the engineer omitted to do that is another question entirely, even if Sky support understand what you are saying.
Edit - Strikeout because the engineer was working on the PSTN not the broadband so wouldn't even know about the speed problem.
