Hi All

I hope you;re well.

I've been running a mini-network in my room (PC, PS5, Smart TV) via a powerline for some-time now and due to various issues with the circuits in my parents' older house, which were causing fluctuations in speed, I finally decided to run a ethernet cable straight from the Virgin box downstairs, all the way to my room. The cable now connects to my TP-Link LS1005 5 Port Gigabit Switch and then goes off to various devices from there - listed above.

The issue is, when the speeds I am getting from the Gigabit Switch are about 1/3 the speed I am getting if I plug the cable (from downstairs) directly into the desktop. In fact, the speeds are actually slower with the cable directly into the Gigabit Switch than I got from the powerline setup I had originally (that also ran through the Gigabit Switch)

For reference, the speeds I am getting on speedtest.net with the cable directly into my desktop is 400mbps. The speed I am getting when I am running the cable to the switch and then to the desktop is 80-90.

At first I thought this might be because of cat5 cable being used (but cat5 was used in the previous setup where the powerline was used to) but in fact because the speeds are below the limit of cat5, i doubt it's the cable, it seems that the switch is in some way limiting the speeds that I am getting.

Does anyone know why this might be? Do I need to purchase a different switch?

I've ordered 5 new cat6 cables to use from the switch for the various devices as a precaution anyway, but I doubt it's that - or am I completely mistaken?

That's for the help in advance and sorry if this is in the wrong section of the forum!

Thanks

Oli
