Lost Internet Connection when using USB Interface of FPC / FSH / FPH / ZVH / ZPH / FSC

Question

When I connect my device via the USB interface, the internet connection of my PC gets lost.

Answer

The main reason in that case is, that the Operating System automatically can switch between the gateways. We have at least two gateways available after the device is connected to the computer. This can easily be investigated by just requesting "ipconfig" in the command prompt.

As standard the new network adaptor is set to DHCP and this also causes the computer to set a standard gateway for this connection.

If the settings for this very network is changed to static IP Address, the original gateway will be used again and the internet connection will work as desired.
