Speed decrease again :(

[#1]

36mb when I first got FTTC, now down to just 20mb   Although I have been told by plusnet that my original estimated speed of 39 was very wrong - 33 was correct - I still don't see why it's now as low as 20.
I'd really like this fixed....along with the disconnections. It's sometimes fine for days then last night about 5 disconnects.

Sorry to hear about the issues guys,
@udk I've been running a few checks and can't see anything obvious so you'd be best raising a fault with us re that: http://faults.plus.net
@albinocory, I can see we recently looked at this for you from a faults perspective. I'd advise running another test at http://speedtest.btwholesale.com as suggested on the last fault ticket and raise that again by the faults link I've given udk above.

tried the bt wholesale test and this is the Test Error I get: The Performance Tester is currently unable to run a speed test for your broadband connection. Please try again shortly, however if this problem persists, raise the issue with your service provider.

I've just gone through the faults page
@albino, did you use it recently already? I think you need to wait a bit between using it

[#6]

@udk its been like that for a couple of days for me lol but did it this morning
@adam walker to be honrst its a waste of time going a faults ways as already had OR out 4 or 5 times out already they say its ok but 1 of them said all he can think off that its the copper wire that's degraded but they wont put a new one in the way its going  we may have to go back to asdl cos its more stable the fttc

[#7]

Could I please get a profile change on plusnet side to match the BTW values?
I've just had openreach engineers out and they've replaced all the outside cabling and performed a DLM reset, so back up to what I started

Sure thing, done.

Not to sound ungrateful, but I'm still getting the same speeds of ~20
Is there something I need to do?

I take it back, waited a bit and now getting 40mb, cheers!
