Disabling RSC should do the trick.
Try to disable Receive Segment Coalescing (RSC), see below.
Open PowerShell as admin and run:
Get-NetAdapter
Disable-NetAdapterRsc -Name "wifi card name from the previous command"
For example:
Disable-NetAdapterRsc -Name WiFi
Disable-NetAdapterRsc -Name "Wi-Fi"
Verify that wireless adapter is set to run concurrently with LAN adapter in BIOS.
Verify please and set correctly Thunderbolt security configuration in BIOS.
Check please that the Thunderbolt device as well as connected USB devices has been authorized and set to always connected
You must have administrator's rights for installing and changing Thunderbolt devices in Windows. You may need even elevated administrator's rights, which may depend on the security configuration in your organization.
