Thought I'd end the working week with a good news story. DLM Does Work!!!!
Although my maximum reported data rate with several different hubs or modems has been around 56 Mbps since January 2016, all this time I've been on a banded profile of 34.999 Mbps with an SNRM of 13dB.
I noticed this morning that the line had resynced overnight, and nearly spat my coffee everywhere when I saw that the line was now operating at 49 Mbps with an SNRM of 8.9!!!
So DLM does indeed do what it's supposed to. Though when you guys say be patient..... you weren't kidding
Personally I think it's down to the amazing stability I'm enjoying ever since connecting the wonderful and super reliable BT Smart Hub. OK... that last bit is a lie.
@licquorice - with results like this you might want to consider swapping your TP-Link for a HH6. I've one going cheap that you could probably prise from my grip
