We assumed they removed the Web GUI so we can't access the line stats anymore, though If I thought if they were attempting to achieve this...
Why on earth would they add the formula for the Line Attenuation? I feel the removel of the WebGUI was for a different purpose...
Ermm...
'we' didn't assume anything of the kind. It was an
initial assessment I made after my
initial examination of the new firmware. That's why I used the terms 'preliminary results' in the title and 'first look' in the post body.
Since then it's become obvious that while most of the config changes
are aimed solely at blocking access, (there are only two which refer to anything else), the removal of the web interface is at least partially due to space considerations. My rebuilt images with the web interface restored encroach the 'spare flash area' by either one or two blocks depending on the presence of the BTAgent.
I'm fairly sure the line attenuation bug you mention is a separate issue as this is somewhere in the underlying interface/driver layer, not the web interface which works normally for non VDSL2 connections.
Of course, it's entirely possible that it's a combination of both which might explain why downstream is now available and upstream is not.
BTW: The only changes I made to the web interface were removing the non-functional BTAgent interface components to reduce the size of the webimg file and some minor cosmetic changes. Engrish spelling and grammar to English.
