Glass fiber, but only RJ45's installed in house?

Hey, I just got glass fiber internet.

When I connect my laptop with a Lan cable directly to the router I have very fast internet.
If I connect my laptop to the RJ45 it seems like its slowed down.
It's still fast, but not as fast as when directly connected to the router.

Any ideas how I can get faster speed through my RJ45's if I connect my laptop to the RJ45 port?

The problem is I can't install new ports everywhere in every room and my router is basically in a room where my laundry is. So I won't be gaming in there, but for now I am.... because of how fast it is lol.

Any ideas? No I won't use WiFi for gaming though lol.

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?

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.
