As you can see from the image my network is 1Gb/s, however my gaming PC does not get more than 100~105Mb/s down while on ethernet. My PS5 and my laptop both get the full connection, I have tried multiple cables of cat5e and cat6, some provided from ISP some from work.
I tried looking around first before making this post, I have done all of the ethernet adapter settings mentioned in this article, I've had a new router provided, I upgraded from windows 10 to windows 11 on a fresh install, I have removed all network drivers before installing the latest from Realtek, and this week I even bought a TP-link ethernet PCI Express adapter and instaled it to my PC and still I am having this issue. I have exhausted just about everything I can think off plus everything I have found online including other post made to this forum for similar issues.
PC Spec's;
Asus Tuf Gaming X570-PLUS (Wi-Fi)
AMD Ryzen 3700x
GTX 1070
Router is Virgin media HUB 5, Ethernet is pluged into the 2.5Gb/s port (have tried others too)
