Yeah so turns out my home network is even more shit than I thought.
I changed my pc from powerline to wireless and the speed dropped from ~50mbit down to 0-20mbit. Apparently that won't be an option then.
Another test I did was my phone (OP3T) laying directly next to my router, which resulted in roughly 200mbit, so a little better but not at all what it should be.
Next up my GFs laptop wirelessly again with theoretical speeds of 866mbit only reached 50-300mbit with huge fluctuations.
The only thing that would help is an actual cable from my router to my pc room, which is kinda complicated. Fuck this...

@Technomancer__ as this is not my house I really don't know how much I can do to it and where exactly the wires run behind the wall. Calling an electrician is probably hella expensive compared to just running a wire along the walls myself.
