Thanks for the reply.

This is a very basic 10 Mb/s Ethernet resp. FastEthernet 100Mb device only. An intermediate switch might magically "fix" the link issue problem

As I wrote, I already have a small switch between the XS508 and the Arduino (It's a Zyxel GS-105B to be exact). This is the same model, that I use in between my Router and the netgear switch and I have other 100Mb devices working without problems. But I can see if I can get 100 Mb Switch to put in between.

I need to get back for this tomorrow, can't look it up right now. But it is an Intel 4th Gen Motherboard, should also be a  Realtek Chip.

Energy saving mode on the Fritz LAN port active?

No, all ports are in power mode / 1Gbit. General "Energy savings mode" is turned off.

One more question: Operating Jumbo Frames?

I haven't changed any settings regarding jumbo frames on any device, so I'd assume they are turned off. On the PC with the 2.5 Gb Jumbo Frames are deactivated in the device settings.
