Sudden Drop In Speed
Just to update on the 3db profile trial line has been quite stable for 26 days which is the longest so far that my line has stayed connected without any re-syncs .
@bobpullen Has there been any further developments in regards to the 3db trial , So far my line has remained stable for 49 days while on the 3db profile so results do look quite promising .
After 2 months of my line being stable on the 3db profile the line has had a resync and speed has dropped to 57Mbps IP profile was at 71Mbps for 2 months now has dropped to 57 have done the usual checks quiet line test incase of any noise on the line but cannot hear anything but noise margin has gone back up to 6db @bobpullen @Anoush as to why its reverted back considering the line had been stable for 2 months.
I am sorry for the delay in my response.
I've recently joined the social media team, and as such I've had to create a new forum account so I don't look at the notifications on my old account very often.
It looks like you're back down to 3db...

The line length looks a bit odd to me as its showing that the line length has increased comparing to a previous test.
It's only an estimated line length, not an actual measurement and its only changed by a few metres so nothing to worry about.
