Fibre speed fallen by 10Mbps in last few weeks

No changes have been made at my end.
As you can see from the associated graph, from Samknows, my actual speed achieved was 60 - 65 Mbps.
The current speed has been throttled - please reset my profile to 65+ Mbps
Attached are graphs of the last 6 months speed monitoring,
Two BT screenshots which indicate that my profile has been limited to 59.3Mbps
Please fix this.

You're going to fall within the acceptable limits of your line, so there isn't much Plusnet will be able to do.
Do you have access to your modem stats?

Re: Fibre speed fallen by 10Mbps in last few weeks

Because I have a BT fibre modem, I don't have access to any modem stats.
Possibily, Plusnet are trying to shave off bandwidth in a cost cutting exercise...

Re: Fibre speed fallen by 10Mbps in last few weeks

This will be a tricky one for the reason AndyH has already mentioned, it's not even a 25% drop which could get counted as a fault.
It's not as simple as "resetting the profile" and the profile hasn't been limited to 59.3Mbps.
The IP profile is directly related to the current sync speed. It's not a banded speed AFAIK. So something has caused a drop in your sync speed.
See if you can identify which Type of Cabinet you are on.
What make of modem is it, and how long has it been on-line?
What's the results of pingtest.net? Also ping ntp.plus.net from a command prompt.
If you put your number into the DSL Checker it will tell you which Cabinet you are on (as well as your exchange which you know doubt know)..

Re: Fibre speed fallen by 10Mbps in last few weeks

Thanks @Anotherone!
That's all useful information.
I would appear to have a Huawei 96/128 FTTC cabinet - however the cabinet number is sprayed on the telephone cabinet (which is definitely 15+ years old); the nearby FTTC (maybe 5 years old) cabinet has no number.
However, it might have worn off as my Plusnet account says I've had fibre since 25/01/2010.  Shocked
Never been this slow before.
I've attached the DSL checker display - which claims perfect speeds.

Those two statements contradict each other. We cannot alter the sync or the profile on a Fibre connection, nor would we if we could.
Sync:
Downstream Speed 61.3 Mbps
Upstream Speed 20.0 Mbps

Re: Fibre speed fallen by 10Mbps in last few weeks

I haven't been getting any downloads of 61.3Mbps and even if I were, it would be considerably less than download speeds obtained only a few weeks ago.

Re: Fibre speed fallen by 10Mbps in last few weeks

You forgot to say what make of Modem it is Smiley
But apart from that, the Samknows results clearly show something isn't right. Even the sync speed is a good 10Mbps below the Range B Impacted estimates. The pings look fine.

Re: Fibre speed fallen by 10Mbps in last few weeks

Still waiting - although the home page says they've answered my ticket - although they haven't.
If I add anything to it, I face a 3+ delay until it gets looked at.
So I thought I'd wait until 15th (that would be 6 days) before adding a stay alive message.  Smiley
Interestingly enough, my current line speed which normally doesn't change from one month to the next has increased by a modest 4Mbps in the last couple of days.
Perhaps I should re-title the subject line to Fibre speed fallen by 10 6Mbps in last few weeks

But it's gone down, even if it's now creeping up Crazy

Why? Tickets no longer go to the back of the queue if you add to them, that was fixed, remember.......then they got rid of tickets for most topics!

Re: Fibre speed fallen by 10Mbps in last few weeks

I think I will wait until after the weekend - there won't be anyone in the office to look at my ticket.  Lips are sealed
