Glass fiber, but only RJ45's installed in house? (self.asklemmy)

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.

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.
