I doubt it makes a real difference to anything, but when I click on "options", under upload modem there's VMG1312-B10A and VMG1312-B10B. I assume the latter is a typo for VMG1312-B10D? AFAICG, there's no such thing as a "-B10B". Having changed mine from (legacy) hg612 to vmg1312-b10b, I (Sandreck, on 6.0.6) see no difference, except in the labelling at the bottom.
On another (trivial) matter, when I set the graph size to anything other than "original" (on firefox), I can see nothing corresponding to "data to show". (Something seems to flicker up and get drawn over when the display loads up). No, I have not fiddled with font sizes. Mind you, it's trivial to go to "original" size, select things there, and then go back to "extra large".
Many thanks for providing this great amenity.
