Latitude 7530 USB NIC keeps disconnecting

I have a user that has a new Latitude 7530 and I have not been able to get this laptop to stay wired (Ethernet) despite using multiple USB-C hubs.

It seems to drop back to Wi-Fi randomly and then the user will need to disconnect the hub and plug it back in and it will work for X amount of time. I’ve used multiple USB-C hub brands and replaced the patch cable from the wall jack but can’t seem to figure out what’s going on here. There is no NIC so a hub is my only option. Drivers/BIOS are all up to date as of today. It’s really effecting MS Teams calls.

I came across this post here in which some users have had success with disabling the power settings on the USB NIC so I just did that under the advanced options and hope that will stick but curious to see if others are having this issue as well.

Adjusting the power settings did not make a difference as it happened again this morning to that user.
