Thunderbolt 3 new dock station no Ethernet controller driver available for P5Q56AV#ABA

[JimLemieux]

Hello,

My company just bought 5 new Thunderbolt 3 docks station with part number P5Q56AV#ABA. (Made in Mexico instead China)

When the dock is plugged on the laptop. We have an not installed network device in the Windows device manager.

The material ID is

PCI\VEN_14E4&DEV_16A3&SUBSYS_168214E4&REV_01

PCI\VEN_14E4&DEV_16A3&SUBSYS_168214E4

PCI\VEN_14E4&DEV_16A3&CC_020000

PCI\VEN_14E4&DEV_16A3&CC_0200

After a few searches on the internet, it seems to be a Broadcom Network Device (NetXtreme BCM57786 Gigabit Ethernet PCIe).

Then I went to download the Broadcom Ethernet Controller Drivers (64 bit) (For external docks) on the HP website. (sp84642.exe)

Unfortunately, it doesn't work at all. The device ID seems to not be listed in the driver package.

Take note that the previous Thunderbolt 3 docks station, bought a few months ago, still work just perfectly.

Where can I find this driver and make the my new docks work as expected?

Best regards,

Thanks for the quick reply!

I just tried all the Softpack that you have posted.

Unfortunately, the Network Controller in the device manager still appears as not installed.

I'm searching on Google for the driver related to this device ID PCI\VEN_14E4&DEV_16A3 and I don't find anything.

So weird!

Hello sir,
I have installed HP Support Assistant with no luck.
6 drivers have been updated,but not the driver expected.
I finally found my driver corresponding of the device ID in the "BootCamp5.1.5621.zip" file.
The right driver seems to be the "BroadcomComController64.exe"
After the execution of the install file, the device now appears as installed.
But unfortunately, there is no new network card for the dock station and the Ethernet connection still unavailable.

It still doesn't work
I don't know what to do?!

Ok, I returned these 3 problematic docks to the vendor and he sent me back new ones! The new docks work has expected.

I don't know what this issue was!
