hey Tim
what is your Cap up and down?
download cablenut here https://testmy.net/forum/index.php?action=dlattach;topic=1013.0;id=64
install it and unzip the attached file in my first post to C:ProgramCablenut
open cablenut adjuster, click delete cablenut tweaks and click save to registry
now go to top left corner, click file, click load custom settings file, browse to
C:ProgramCablenutvanburens_cablenut_settings_version_DSLDSLWinXP_2KMSS1460
dubbleclick on Cable & DSL 1000 256.ccs ( if that is your cap, 1000 Kbps down and 256 Kbps up )
if you have more then 1500Kbps down, then use the 1500+ files
now you see some values in adjuster, click save to registry again + reboot your pc
now do some speedtest and one more tweaktest
