There was a recent thread on here where someone lost 20% of his downstream sync speed in one go.

Will you post the link, please?

Sure. I was thinking of this thread.

Thank you. Much appreciated.

as crosstalk increases (more people subscribe to FTTC) you will slowly see your speed degrade.

That's not necessarily how crosstalk works. You can have many connections that do nothing to your speed, then one further line is connected that interferes badly with yours and drops your speed significantly. There was a recent thread on here where someone lost 20% of his downstream sync speed in one go.

BT Openreach are experimenting with vectoring, which will help to eliminate the effect of crosstalk. Unfortunately, deployment still looks to be some way off.

agreed but given his cabinet is 2 years old, hopefully any crosstalk is already in place so his speed stays as is.

Folks,
Thanks for all the advice.
David-W I found that link very helpful too.

I'll just have to tour the neighbourhood discouraging any further take-up of fibre

It seems unlikely though - 23 to 13 is a big drop and I wouldn't think crosstalk would be that bad.

My speed has dropped from 69 Mbps to around 56 Mbps and there's at least 10 fibre connections coming from the same pole as my line so whether this could be caused by crosstalk, I have no idea.

I must admit I was thinking any drops would be a percentage rather than in terms of absolute figures but I could be wrong.

My own connection dropped from 80 to 72, then interleaving kicked on and now it's 65. So that's a total drop in 18 months of either 18.5% or an absolute drop of 15Mb/s. 18.5% off the OP's current 23 ain't so bad but a drop of 15Mb/s would be painful. Then there's banding to consider.

So I don't know. I'd rather hope as Mr Saffron wrote that it being an established cabinet means he's already dealing with crosstalk but we've no way of knowing. Hopefully they'll come back with a status report in a few months

My max achievable has went from 110Mbps to around 89Mbps in 10 months.

When I got infinity installed my estimate was 41.6 down 6.5 up in reality I getting about 53.24 down and 13 up it's still good!

As others have said, your speed will probably drop.

BT line here (via the excellent Plusnet), predicted speed: 59/20

When the engineer came, his test equipment said 72/20. This translated to 62/15 when the modem was installed (direct on the master socket), and dropped to 50/15 within a couple of days. Currently the cabinet is 1 week in service so probably near-empty aside from us, so we have crosstalk to look forward to as well.

It's no longer playing rollercoaster during busy periods, so that's something.
