Ethernet Speed Crashes via DynadockU3

[AlbanRampon]

Hey John,

That's indeed quite strange. Would you be able to attach the zip file of your log generated with the guide in my post signature?
Please take them when the issue is present.

It will tell me how the network is configured.
Plugging the docking station without any Ethernet cable in it should have no impact as Windows shouldn't try a network card with medium disconnected.
DisplayLink Manager (the resident software and Windows service) are only for the graphics part and don't need to fiddle with network parameters.

Kind regards,
Alban
