just for info,, this is the details from my router,,, 8meg max rate bt line

so my router is showing 7616 kbps, or 7.6 meg..
the lower the loop attenuation the shorter the line generally..
also the higher the snr this would point to line issues and this is raised to combat line quality issues, but will effect sync max rate speeds,,
also the errors are not good....
my speedtest. net result...
