Fritzbox 7590, if I connect a laptop directly to the router 25 / mbs but only 5 / mb in my room?

I have a Fritzbox 7590 and a 250,000 contract, which also come in when I connect a laptop directly to the router, but when I connect a Fritzbox Powerline one room further I only get 5 / mbs instead of 25 / mbs with my father Further down the room it is exactly the same that only 5 / mbs arrive, what can I do?

Do without the Powerline and pull a cable.

D-LAN is just a thing, depending on the quality of the wiring in the house, there are violent losses…

How do you mean? A cable through the whole house or how

For example.

Is there another option

Wireless Internet access. But that can be better, but it doesn't have to be.

But there will be a reason why you are not using Wi-Fi.

Depending on the construction of the house (no reinforced concrete) also multi-channel Wi-Fi, possibly with a repeater in the middle
