I assume, in Plusnet's defence, that they were not one of the trialist CPs.
No, they weren't.
Initially, it was geared toward LLU operators, but Alex R at Plusnet informs me that they are now definitely looking into adopting it.
Maybe, just maybe, I will get my "potential" HR issue "thoroughly" investigated one day.
I still have quite a high error count (27000 CRC errors within a 1 minute sample yesterday morning), & lower speeds than at first.
In theory, I believe the switch from profile 8c to profile 17a should actually have given me quite a substantial speed increase.
It appears to have done so for many others who weren't achieving maximum speeds on the 8c profile.
It only really appears to have increased my error count, though I'm not 100% sure about that as I couldn't really monitor them until quite recently.
