From the faster line, which is now SNR tweaked back to around 8dB...

On the other line, there are a lot less errors (although I've not reset them since the connection last reset so the stats are meaningless), however this jumps out:
D (interleaver depth): 96 2
Not seen interleaving get that high before, theoretical max speed is reporting as 3ish megs, connecting at 2ish, and it's moved itself back to a 6dB SNR margin from 9dB previously...
