I'm trying to connect a USB Type-C (Thunderbolt 3 compatible) ethernet adapter to my new 730-151IKB.
If I have the Device Manager window open I see the adapter added to the list of adapters, but with the yellow triangle against it. A couple of seconds later, the device drops from the list.
I've tried re-installing the Windows driver and also installing the latest Realtek drivers, to no avail.
Any ideas as to why it doesn't install.
Solved! Go to Solution.

Welcome to the Community,
You may try downloading the Intel Thunderbolt (TBT) Driver below,
Update us how it goes.

Sorry, I meant to reply earlier, but RL got in the way.
Updating the Thunderbolt driver made no difference. I still got the same results, in that the ethernet adapter appears in Device Manger for a few seconds and then disappeared.
I actually found the solution while fixing another issue.
It appears that the Check Point VPN software, which I had loaded, stops any other modification to any ethernet adapter. To fix the other issue I had, I removed the CP VPN and then as part of that fix had to re-boot. After re-booting, the ethernet adapter for the Thundebolt adapter was present and working. Of course, now the adapter is there, I could re-load the CP VPN and everything still works.
