I think you have a MTU conflict with your NIC, TCP optimizer force your NIC to use 1500
do like this, open TCP optimizer, click restore if you have a backup
if not, blank out where you see a MTU value, so the field is clear then click save
dont reboot when asked
now install cablenut 4.08
http://testmy.net/forum/index.php?action=dlattach;topic=1013.0;id=64download this setting file i attach, unzip the settings to C:\Program\Cablenut
open cablenut adjuster, click delete cablenut tweaks + click save to registry
now in top left corner click file, click load custom settings file
browse to the file you unzipped and dubble click on that
click save to registry again and reboot your pc
good luck
