Fixing issues with the Belkin Dock Utility

Symptom: The app is in the grey error state and persists in that state even after a cold/warm boot or install/reinstall.

This case was caused by a bug in prior releases of Belkin Dock Utility (was Belkin Dock Manager) and should be resolved in v2.6.4 and later. Grey disconnected will be displayed if no dock or adapter is attached.

Cause: The app is confused about the MAC Address Pass Through (MAPT) state based on the following two items:

a. The Network Interface Controllers (NICs) of the laptop are enabled or disabled.

b. There is a MAC address cloned in the network driver settings of the adapter or dock.

You can try the solutions below.

Solution #1: Confirm the Dock Manager Utility service is running.

1. Click the Windows® Start button or search bar and enter “Service”.

2. Choose Run as administrator from the right-hand list.

3. Locate the Belkin Dock Utility entry in the Services list.

4. Start the service if Status does not show Running.

5. If the Belkin Dock Utility service is not listed, download and install the software.

Solution #2: Confirm the adapter/dock is enabled.

1. Type "View Network Connection" in the search bar and run it. Then locate the laptop’s NIC.

2. Locate the adapter or dock network connection and enable it if it is disabled. The name of the device depends on the connected adapter or dock.

3. If an adapter/dock cannot be found, check the adapter/dock connection, and confirm the attached device is supported by Dock Manager Utility.

Solution #3: If there is another MAC address in the driver setting of the adapter/dock.

1. Type “Device Manager” in the search bar and run it.

2. Locate the network adapter of the USB-C® dock or adapter.

3. Right-click on the USB-C adapter or dock NIC and click on Properties.

4. Click on the Advanced tab in Properties, then locate the Network Address in the Property column.

5. If the Value box of the Network Address already contains the MAC address of the laptop, then click on the Not Present radio button and then click OK to set the Network Address of the USB-C adapter or dock to its default MAC address.
