Is it happening that your PC is still experiencing slow internet connections even though you're using a 1 Gbps plan?

Thank you for the suggestion to reset the network settings. I followed the instructions and reset the network, but the speed hasn’t improved and still stays around 300 Mbps. Considering all these attempts, the problem seems more complex, possibly involving hardware issues. If you have any other advanced settings or diagnostic steps in mind, I would really appreciate it. You might also want to try an external network adapter to determine if the issue lies with your current network card.
I also thought about recommending an external non-Realtek USB adapter (like ASIX), but you mentioned the Wi-Fi was also restricted.

Would you have thought about upgrading to Windows 11?
The described setup involves connecting an ethernet cable from the modem through the router to the PC, without any switches. The diagram should reflect this path clearly. If the modem functions as both a modem and a router, its DHCP services must be turned off. Please adjust your line diagram accordingly.
Do you have another pc type device that is connected via ethernet. The goal would be to test inside your house between 2 devices and see what you get for transfer rates and compare that to the speedtest numbers. There is a old line mode tool called IPERF3 that can be used to test transfer. You could i guess use a file transfer and watch the numbers in resource monitor, just be aware some numbers in resource monitor are BTYES/sec and other BITS/sec.
You could try a USB bootable linux image. This will not damage your windows install. Most images have a browser preinstalled and you can run the same speedtest you do in windows. This is mostly to confirm it is some strange issue with windows driver or configurations. If the linux image has the same slow issue then you more suppect hardware.

WiFi adapter and Bluetooth were activated on my PC, so I disabled them. The ipconfig/all output is as follows:
