Hi,
CoolTuner does reapply the ndd settings after a reboot. The /opt/cooltuner/rerun_on_reboot directory should contain a file called networkmods. This script contains the ndd changes and it should be automatically executed after a reboot.
You can copy the script to /tmp, for example, then change the "-set" parameters to "-get" and remove the last parameter (the number). Then run the script from /tmp to check the current settings.
Hope this helps,
Allan
