What are the impacted figures?
The full works:
VDSL Range A (Clean) 60 - 41.6 --- 13.7 - 8.5 handback 35
VDSL Range B (Impacted) 58.7 - 37.7 --- 13.5 - 7.9 32
And to remind, current connection is (down - up)
Attainable throughput kbit/s 40058 13156
Current throughput kbit/s 38477 9997
From what you have said, there is very little you can achieve inside the property
I can move the Master socket thus removing maybe 12 metres of xDSL run over Ethernet.
Did the installer use a pair in the Cat5e (Ethernet) cable?
Yes, the twisted almost matching blue pair! Also, and is this of relevance, he then used another pair in the same Ethernet cable to run an extension back from the Master where there's a normal phone point. (Never used, no phone connected but working.)
Disconnect the unused extension, and plug into the face plate. the small differences in Upstream between 13025 and 13126 will change regularlyYes, I had it like that for a few weeks but I didn't make regular checks. SNR only went from 8 to 7 though.
