Only 93 Mbit/s even if Lan is Gigabit and I-Net-Speed is 250MBit/s

I have this network-card:

Atheros AR8161/8165 PCI-E Gigabit Ethernet Controller (10/100/1000MBit/s)

At my router, I got 274 Mbit/s:

But at my PC, I only got 93 Mbit/s.
The PC is connected with a LAN-Cable, straight to the router.

How can I figure out, why I-Net speed is so low at my pc?

I got it.
In FRITZ!Box, you can set Green-Mode to your LAN-Ports, which limits the speed to 100Mbit/s.

I’ve switched the port where my PC is connected to GB, and it has full speed now.

They should add Gluten-free 10Mbit/s mode.
