Is this normal / acceptable, or a problem that can be fixed?

Hi,
I am happy to say that I have an FTTC connection as of a couple of weeks ago and during the day it is great: around 55-60 down and 15-18 up. My problem is that after around 5 or 6 pm, the down speed often drops to 5 or 6 mbps and sometimes as low as 2 or even less.  Cry That doesn't really make the things fibre is good for (streaming, downloading TV catch-up, etc.) viable.
Is this something that could be considered "normal"? It's seem likely to be something to do with contention, but as I live in a small rural village and we have a brand new cabinet, tsuch huge speed drops don't seem right.
Is there anything that can be checked, or anything I can do to find the cause and (hopefully) a solition?
Adrian
P.S. these speeds are via ethernet connection to the Hub One router.

Re: Is this normal / acceptable, or a problem that can be fixed?

The FTTC in your cabinet will not be connected to your village exchange but to a 'head exchange' which is probably in a nearby town and it' will almost certainly be that which is overloaded.
Run a BT diagnostic speed test when it is going slow and make sure you don't run another when it is going fast so that the last test BT see is below the acceptable speed.
Then raise a speed fault at http://faults.plus.net

I've also noticed how slow my FTTC connection gets at peak times during the evening.
It often drops to around 3Mbps which is no better than we got, at that time, with adsl.( We have 40/2 and get 36Mbps in morning)
As we are about 350 metres from cabinet I've put it down to demand.
We watch a lot of " on demand" services using Roku HDMI Stick and overall our viewing hasn't been seriously affected.
Does, however, make adverts seem a joke.

Have you raised a fault?

Try running the Thinkbroadband test. See if there's a disparity between single and multithreaded download tests.

Have raised a fault so will see what happens  Cool
A 90% variation is rather extreme - 36Mbps to below 4Mbps
Connection seems perfectly stable.
Plusnet Hub One is plugged straight into master socket

We need to see the tbb speed test when it's running slow please.

Re: Is this normal / acceptable, or a problem that can be fixed?

Well it's not the single threaded issue so probably just boring ol' congestion somewhere. Given we don't have many complaints here I'd assume it's fairly local to you. Your exchange most likely. I can't see it being the cabinet links back to the exchange as they are new (and anyway BT can easily upgrade them) but I can believe that BT failed to upgrade the exchange backhaul. Where is your nearest town?

Re: Is this normal / acceptable, or a problem that can be fixed?

If you haven't already done so, you need to run a BT diagnostic speed test when it is running slow.
If you are asked to run another test only run it when you know it is slow otherwise they'll take a test run in the morning at normal speed as it's fixed and BT will close the fault!

Speed even slower than I got with adsl during evenings
Only things I have currently connected is this laptop and my mobile phone.
So much for super fast fibre  Angry

Re: Is this normal / acceptable, or a problem that can be fixed?

Are you using a wired or wireless connection to the router?
If it's wireless you need to test wired to rule out local interference with the Wifi.

Not possible at present but problem exists on 2.4 and 5Ghz
Just added this to ticket

For your connection, the acceptable range of speedsis 20 Mbps-38.67 Mbps .

Then it may not be possible for anyone to progress this further. Wifi is simply not reliable enough at any frequency for people to take connection performance issues seriously.
Why is it not possible? All you need is an Ethernet cable to connect your laptop to the router.
