@kermit1991 Do you see this issue on all your clients or just when using an USB ethernet adapter? Have you tried using the ethernet adapter together with different clients. Sometimes adapters and client’s BIOS/UEFI firmware just don’t play together well enough. On the other hand some USB ethernet adapters just don’t play nicely altogether. It’s a long process to figure out what exactly the issue is. So start by telling us more about the exact USB adapter you have and make/model of PC/laptop you use.
