Fibre dropped by around 10mb

[#1]

Hi there,
Can anyone tell me what could make my fibre connection sync at a lower speed?
When I first took out fibre a year or so ago, I'm sure I was synching at around mid 60's, now on checking my PlusNet member centre, it seems my 'current speed' is around 52mb.
I'm not sure if that's generally over time, or just a recent thing.
Seems to me like that's dropped quite a bit.
I've also noticed things like youtube on my ipad seems to buffer quite a bit.  Particularly if I skip forward a few mins.
Thanks
Carl

Join the club mate. There's a fair few of us, I was syncing at 77.43 for well over a year and over the past few weeks I'm now down to below 60... just keep getting told to live with it and 60 is all your line is capable of when clearly it isn't syncing at 77.43 for so long.

The buffering could be a wireless issue. It should be fine at those speeds though.
I'm running a line test now to see what sort of speeds you are getting and if we can see anything obvious.

Two things I've noticed.
1) "Voice fault suspected - contact Voice CP to progress copper issue". It's worth checking out your phone line to ensure it's all ok. This error message may be a red herring though, so if they can't find an issue, ignore it.
2) Your line is G.INP. BT are rolling out a updates to this. I'd expect if this fixes it, you'll see an increase.
At this time, I'd say that there isn't much point raising a fault, at least in the short term.
