Loosing Data over USB NIC/Ethernet Adapter

Hi all, I wonder if anyone can help here. I have a 2021 Razer Blade 15 Advanced and I'm loosing data over USB NICs. So far I've tried a generic Chinese 1gb adapter, a TP-Link UE300 1gb and a CableMatters 2,5gb. If I plug a different machine onto the same connecting hardware that side of it works fine but on the Razer I'm loosing data as soon as the load goes over about 300Mbps. It doesn't matter if I connect to the USB3 or USB-c. Specifically I'm trying to use NDI video ingest and it's loosing frames in random chunks. Many thanks.
