Installed a MK2 faceplate this morning, so far it has nudged my downstream speed up by another megabit or so.
Current Results:
Max: Upstream rate = 29547 Kbps, Downstream rate = 100780 Kbps
Bearer: 0, Upstream rate = 20000 Kbps, Downstream rate = 68999 Kbps
The attainable rate hardly changes for me no matter what time of day it is, a variance of at most 500-750Kbps on the downstream and upstream. I'll update after 24 hours or so once I have sufficient statistics to know whether or not it has reduced my errored seconds and/or CRC's. My sync rate is deliberately 68999 because I've done 'xdslcmd configure --maxDataRate 69000 20000 89000' to see if I can do what I did over a year ago (stick DLM into a banding state with no interleaving applied, at the moment I'm interleaved at INP 3 with delay 8).
