Thank you for the additional details and testing, I can confirm the Netgear EN104TP 10Mbps Ethernet Hub is not compatible with the docking station. I recommend using a gigabit Ethernet Switch, these are widely available and can provide for significantly better performance, especially when connecting to multiple computers. Hubs like the EN104TP broadcast data packets out all connected ports while switches target the packet to the port with the destination computer connected. This helps to reduce network congestion and increase throughput between devices. Additionally the speed improvements from 10Mbps to 1Gbps are significant for file transfers, web page loading times etc.
Please note, additional 10Mbps hubs in between the docking station and the destination device or network router will cause the connection speed to be reduced to 10Mbps.
Thank you, and I a look forward to your update.
