CableNut is a tool for optimizing your Windows TCP/IP stack i.e. your Internet Connection. We have provided a way to tweak almost every possible TCP registry entry via the CableNut program. You can load CableNut Custom Setting files that are included with the program to tweak your Internet connection. You can make your own CableNut Custom Setting files save them for later use, or distribute them to anyone with the CableNut program.

Dialup, Cable, and DSL connections are supported out of the box. If you don't have one of the supported connection types don't worry you can visit the forums, and ask the CableNut team for help. Best of all it is freeware. We don't haggle you with anonying ads, banners, time limits, or restrictions.
