ADSL Max - Pro add on or Max Premium trial?

[#1]

Hmm, not sure if it's already been tried (sorry if it has) but we could always run an SNR reset on the line and see if that updates things?

[#2]

Happy to give it a go - anything to help!
Wouldn't have thought Snr would be affecting it though.. Wouldn't we be seeing a lower sync rate or something similar?
It's as if there's a limit on the line somewhere upstream of our physical connection - all looks great in terms of sync & line speeds, yet upstream seems capped somehow.

The SNR reset actually resets everything on the line to back as if it was newly installed, and allows it to retrain. I suspect you're right and there's an incorrect profile on the upstream across some of the exchange kit, the SNR reset *should* sort that out - here's hoping. I'll put it through for you now.
EDIT: Sorry, I can't do that as the order to put you back on to Max Premium is now going through... I'll do it once that's completed.

Thanks Matt

Hi Matt, Chris & Adam - any idea if the order to re-add Max Premium has been completed yet; and whether an order has been placed to reset our SNR ?
Our line has been performing badly throughout the weekend; slow downloads speed with upload measurable at around 80-90Kbs during a good moment and high latencies.
Router restarts / reconnects haven't helped so can only assume it's something at the Exchange or Plusnet ends.
Very keen to get this sorted as so far our connection has taken a distinct nose-dive towards the ground since being ported over... Not exactly inspiring much confidence right now although I do of course appreciate things are happening, albeit slowly.
Any update would be greatly appreciated.
Thanks both
Tim

Is there any update for this issue & support cases please?
I'm keen to get it resolved as quickly as possible as the line's not been good since our connection migrated to Plus Net on 09/12/13.
Downstream speeds vary wildly currently from 1.2Mbs to 6.7Mbs and upstream is at best 120-200Kbs. Prior to migrating our connection performed consistently, delivering a steady 6.6-6.7Mbs / 720Kbs on the same line with the same router - and had done for the previous 2-3 years... 
All in all, a long way away from the fast & reliable service you guys are supposed to be offering
It's pretty clear that removing & adding Max Premium has had little to no positive effect, so what's next? SNR reset? If so can this happen today?
