I've recently set up Ethernet in my room, connecting directly to the downstairs router. I've tested the connection with my laptop, which is using a USB-C Ethernet adapter, and it consistently reaches about 1.1 Gbps. However, when I run the same test on my PC, which has an onboard Ethernet port, I'm only getting speeds fluctuating between 500 and 800 Mbps, often settling around 600 Mbps. Interestingly, using the same USB-C Ethernet adapter on the PC gives slightly better results, but it still drops significantly at times. Yet, internet speed tests report I'm hitting the full 1 Gbps. Why is there such a discrepancy in speed and stability between my PC and laptop during real-world usage?

Also, keep in mind that if Steam is downloading and installing updates simultaneously, it might not use the full bandwidth available, which could lead to the lower speeds on your PC.
Make sure to adjust your power settings on the PC. Set it to performance mode and disable any power management settings. Sometimes, Windows cuts power to the Ethernet while it's trying to save energy.
You might want to check your motherboard's website for updated LAN drivers. Sometimes, outdated drivers can affect your Ethernet performance significantly.
