I have a problem that support - even thrid line cannot seem to resolve and any thoughts might be useful.
The figures vary by maybe 100kbps after a reconnect but nothing more.
I have a good quality line on a low usage cabinet. The max achievable is 77.6 Mbps and the sync rate 76.1Mbps and that is fine.
However, the IP profile is 66.4 Mbps and various speedtests - BT and thrird party come back with about 64.5 Mbps and with that IP profile it is reasonable.
What I cannot get an explanantion for is the discrepancy between Sync and IP profile - I would have expected them to be a lot closer with an IP profile in the region of 72-74 Mbps for a 76+ sync.
Any thougts or comments on why and how it can be resolved. Profile resets have NOT resolved it. Is there an issue or is some other factor comin into play.
When the VDSL connection was first made the max acvievable was over 80Mbps and speed tests of over 75Mbps were commonplace - obviously cross talk from other lines has pushed it down slightly and I accept that happens.
