Router slowing LAN down from 240 to 50

[Tom01]

When I connect my pc dirrectly to the modem I am getting 240Mb/s down and 20 up, but if I plug in my router I am getting only ~50 down and 20 up. In my routers settings I didn't find anything that would limit the speed and the PC is connected to the gigabit port. Can someone help me solve this issue?
Thanks Tom

Fritz!Box 7360 is my router

That router has some fast ethernet ports. That will limit to 100Mbit. You need a new all gigabit router. The Netgear R7000 would be a good choice.
