Finally just to throw random phrases at you.... G.IMP and vectoring... are these relevant to VDSL - I've read that the smart hub doesn't support them but the network does?
Take a look here for an explanation :-
This is through the test port, a new filter and a different rj11-rj11. Oddly slightly slower but within the realm of ‘it just is’.
so I’m still basically losing around 5mb sync from the front of the house to the side via a brand new cable - unless the engineer was wrong when he said the sync speed there was 60mb.
As that is virtually the same speed and attainable speed it does not look liked your line is capable of going any faster
Apparently so 😞
I’ll still probably get an alternative modem at some point just for the lols and to prove myself wrong but yep. Still think it’s weird though!
(I’m aware first world problems etc - I’m arguing over ‘only’ getting 50mb here)
edit: really oddly I do get a faster speed without using the test port. I do think I’d be able to eek out a little extra with the right modem. Noise is now 6.1 / 6.1 but the sync speed is higher. Anyway stability is good..
