I've replied to the ticket for you.
I do understand the variable speed issues with MaxDSL
What seams to be my problem is my BRAS profile keeps getting messed up
its now been referred to BT twice now, what makes the BRAS profile get corrupt
I am running logging software to check my router sync settings and there are no drop outs or changes in sync speed at all the SNR stays around 11 to 13 day or night
I just don’t understand how the BRAS profile keeps getting messed up!
