When we joined Infinity 2 we were quoted a theoretical max speed of 80mb, though tests would usually top out around 76mb over a wired connection, which I was more than happy with.
Then a few months ago we had a problem with the connection and an engineer had to come out and repair (not replace) the cable outside my house. After this the sync was still 80/20 but the speed dropped down to mid 60s, so I gave BT support a call. This is where it gets confusing.
The lady I spoke to insisted the maximum sync speed is and always was 73/20, even though I am, and always have been, connected at 80/20, and that the maximum speed they offer is 73mb, even though I've constantly obtained higher. So it looks distinctly like BT have decided to limit the maximum speed we can achieve, whilst constantly increasing the amount they charge?!
Should they not legally be providing the maximum speed our lines can support? I've lost around 10% of my speed yet the hub's sync speed is no different, so clearly something is limiting it artificially. They also didn't inform me of any changes, including of which package they had me on, that's a little suspect, too.
Can you post hub stats if hh6 then advanced settings then technical log information

Run btspeedtester and when first test completes then run diagnostic test must be done with Ethernet connection
My question is more about how BT seem to have switched people from a package with an 80mb max speed to one with 73mb, without warning.
An increase in crosstalk from other customers on the cabinet will cause a drop in connection speed.
BT do not sell a package with a max 73Mbps speed.
to be able to get more idea of your problem and then provide some assistance you need to post the information I requested
Chances are the rep was either wrong, or didn’t explain themselves very well, FTTC VDSL is capped at 40,55 or 80Mb, if your individual line is capable of delivering the highest band, and you have purchased that band, your router will sync at that rate, obviously if your line cannot achieve the upper bands , it’s probably not a good choice to purchase them ( some may do that for the improved upload speed though )
ISP’s cannot market products as they once did in the past ( so no longer should you see ‘upto 80Mb’ ) they have to use ‘average’ speeds a typical customer of theirs on that band get , so in simplest terms , say they had 2 customers both on the highest band , one getting 80Mb, and one getting 60Mb the advert would have to be ‘average speed 70Mb, one getting better than average , one getting less, obviously in reality it’s millions of customers but the process is the same, it could be the rep has quoted what a typical BT customer on Superfast 2 ( or whatever that band is marketed as ) gets, for al, the use it is, personally I think the old ‘upto’ way of advertising was no worse than the average speed they now have to use.
As others have already stated if your line once synced at 80Mb but now syncs at less, it may well be due to cross talk from adjacent circuits , the more people that take the service the more likely cross talk becomes an issue , and DLM may reduce your sync speed to give a stable service, or their could be an issue ( fault) with the ‘line’ , and DLM again has intervened.
For what is worth, I’m on 80Mb, ( around 80 metres from the cab ) and sync at 80Mb, and have done since the service was provided.
