Make sure your switch(es) are actually getting the full speed. Despite good cables, they could be negotiating at lower speeds. Also check that your router isn't limiting bandwidth in its configuration somewhere.

Set up iperf on a machine connected to your router.
From your machine, connect it to the router too and see if iperf shows good speed.
Take your machine to another room and plug into your lan and test again.
If the speed is considerably lower then yes you have an internal network issue. I would look into how the cables connect to the router. It might be an old or cheap switch. It could also be the cables or cable ends themselves. I’ve seen cables that are terminated poorly cause slowness. I’ve seen two connections in a single cable end work but have lots of problems.
I recently bought a house with Cat-5e. I noticed that my switch was registering dead ports and a lot of ports st 100mbps instead og 1gbps. It turns out that most of the cable ends were crimped incorrectly. I would suggest you check your lines with a double ended cable tester.
Every single port, cable, switch and router between your fiber ONT to your laptop has to support that bandwidth. What model is your laptop? What model is your router?
When you say directly connect to the router, are you physically right next to the router testing the speed? Or are you plugging your laptop into ports installed throughout your home?
From each point in your network do a speed test.
Http://speed.cloudflare.com is excellent
Do these tests with wired connections.
For gaming, the thing you really care about is latency and packet loss, even if your total bandwidth is lower, it shouldn't impact gaming. Especially at fiber speeds, if you're only getting 300 instead of 1,000 megabytes per second you will have no problems gaming
If you see packet loss and high latency on your wired connections, there's probably interference, the cable might be running parallel to a power cable, it might be damaged, it might be poorly terminated.
Ethernet cable is really cheap, you can just run extra cable. On the floor even and tape it in the corners of the walls. You can fish it through the wall cavities.
If that's not an option, you can use powerline ethernet, which will not be as good, but it will use your power lines, so you won't have to run cables.
If you're still having problems, please describe your network and detail to us, including the kind of cables you're using example:
Fiber-isp router-cat 5a cable to living room-switch in living room-cat 5a cable-gaming computer.
I only use cat 7, it says cat 7 on the Orange cable
It's time to measure and get empirical results
The speed that you get through your rj45's depends on the quality of the cable used, both 'in the wall' and from the socket to your device. For 1Gb/sec they need to be cat 5e or better.
I only use cat 7, it says cat 7 on the Orange cable
Doesn't mean shit if the RJ 45 doesn't support it or is hooked up incorrectly or if the cable has some kink somewhere resulting in a lose connection or if the patch cable between the laptop and the RJ 45 is bad or the RJ 45 or patch panel on the other side is bad or the internal cable loops a hundred times around the house before getting hooked up or the cable has faulty shielding and is next to some other cables.
That's all I could think of off the top of my head.
You got downvoted but you are correct. I had to re-crimp more than half of the cables in my house. Before I did, whoever worked was gimped at 100mbps.
