Last updated: 20 Feb, 2020

The EZ-Dock utility software is designed for a Windows computer to clone (passthrough) its internal MAC address to a Cable Matters adapter/dock with Ethernet that connects to the computer.

Refer to the steps below about the setup process.

Download and install the EZ-Dock utility software
EZ Dock setup

EZ-Dock setup
Double-click to run the EZ-Dock utility software

A welcome message will appear in the lower right-hand corner of your screen when EZ-Dock starts up.

Click the “Show hidden icons” arrow next to the notification area in the bottom right-hand corner.

Right-click the EZ-Dock icon and follow the steps to set up the software.

  • Enable WIfi Auto-Switch: When checked, EZ-Dock disables the Wifi network card while a Cable Matters adapter/dock with a wired network is connected and has internet access.
  • Enable MAC Address Passthrough: When checked, EZ-Dock clones the computer’s internal MAC address to the Cable Matters adapter/dock. Note: The CMI adapter/dock must be connected and have internet access.
  • Run on system startup: When checked, EZ-Dock will start automatically during Windows startup with saved configurations.


EZ-Dock only works when a Cable Matters adapter/dock is connected and the internet is accessed through the Cable Matters adapter/dock. Unplugging the Ethernet cable or the Cable Matters adapter/dock will stop the EZ-Dock program (the EZ-Dock icon is grey when turned off). The initial settings of the computer’s network card will be recovered.

When EZ-Dock is closed (either manually or automatically), wait at least 10 seconds to restart the utility software, otherwise, you may receive an error message: The program is already running.

After 10 seconds, if starting EZ-Dock still sends you the above error message, reboot the computer and restart the utility software.
