Unfortunately everyone want everything cheap - they decide on price and NOT performance in too many cases.
Sounds like the UK broadband market..

Exactly ... whether it is the overall price where the ISPs have to outsource to India to cut a few pence of the costs, or supply bottom end modems/hubs/routers.

Which you can't either.


Dunno, haven't seen it defined precisely enough yet.

IP Profile is 96.79% of sync. There are no sync's above 80Mbps.

My broadband basic info/help site - www.robertos.me.uk | Domains,website and mail hosting - Tsohost.
Connection - Plusnet UnLim Fibre (FTTC). Sync ~ 54.2/15.2Mbps @ 600m. - BQM

I think I got in a tangle with your introducing a surmise about what he meant as opposed to what he said. Hence my reversion to the Subject of the thread and thinking we were talking about FTTC IP Profile.

Reverting to your original
In reply to a post by yarwell:
claiming the 80mbit sync I had originally was not possible as requires FTTP
perhaps he meant you can only have an 80M IP Profile on FTTP.
even by your own argument here and in this post the engineer would have been talking twaddle if he had meant what you suggest. Which is what Chrysalis was saying and you were replying to.
The engineer wasnt particurly great either badly trained or deliberatly trying to mislead me, claiming the 80mbit sync I had originally was not possible as requires FTTP.

that depends how the 80M FTTP product is defined, which I don't know. It could be for all I know an 80M IP profile, which was where my loop started.

my line is been monitored for a week now as was stable over the weekend, no engineer was booked as I expected.

DLM also swapped me back to fast path which has my sync just below my estimated speed now so if the line is stable between now and then I think they will close my case, even tho the engineer visit was a bit of a sham.

case is as good as closed now unless the stability is compromised again but has been stable on fast path all week.

I am on a 62mbit IP profile, originally was the full 77.43. Also I am not even seeing variations on noise margin and attainable now. So its possible they did do something but just not saying so. BT have told me tho as far as they concerned the 77.43 down to 62 profile is not something to investigate even tho my line could do 110mbit on day 1. So I havent got anywhere on that.

So in my case I guess I just wait for vectoring, that will prove if its crosstalk or not.

The stabilisation may also be related to the fritzbox which I put in since sunday, it has incredibly low errors compared to the hg612.

I am still in 2 minds, realistically 60mbit is pretty good for the uk, and for me it is good enough. But I have a mind that wants the best and it has bugged me the lost attainable but the main reason I did contact them was the long outages which have stopped.

Also my line is on a 74mbit banded profile, which is irrelevant currently as its synced below that.

However if it falls down nearer to 40mbit, I may downgrade, whilst 20mbit upload is nice to have I dont actually upload often, and I wont be paying for missing performance.
