Difference between Dell Port Replicator PR03X vs K07A002

We do have some issues with our Windows 10 laptops which are using the Dell E-Port port replicater. The problem is that the network switching between wireless/undocked and wired/docked is not working properly.

When docked the laptop can't switched to the wired connection and no network is available. When removing the network cable from the E-Port, the laptop switched to wireless connection.

Help.

I notice that we have two models around here: Dell Port Replicator PR03X and K07A002

Could someone explain to be the differences and if one of the two is not supported by Windows 10 ??
