Mine is similar on the downstream, and has been for months - through many re-sync's.

IIRC it is usually the unexpected way up on upstream as well.

Engineer came last week, all his tests pasts which didn't surprise me as the issue appears to be intermittent.

He went out in his van and found a big source of REIN just near my house and he tried to build a REIN case but couldn't as the interference doesn't seem to occur at any time of day, it's just always there. Coupled with the fact that the connection is quite stable (although erroring a lot in my view) meant he couldn't open a REIN case.

TalkTalk are being quite useless, they just want to close the fault. I don't think they're going to be much help (they lack proper line testing tools, historical line data, etc.) so I think we'll be moving to Plusnet.

Still having issues...

Getting absolutely nowhere with this.

The connection is stable yes but the performance just seems to be so meh!

Hlog still looks bizarre: http://imgur.com/rT9BhD4
