Ethernet speed capped at 100 Mbps

I have a Lenovo Legion T5 28IMB05, and my Ethernet connection is capped at 100 Mbps.

Things I have already tried and didn't work:

• Switch to another cable. Originally, I had a CAT5e and as my speed was capped, I bought a CAT6. It didn't help (though I'm still using it)
  
• Force the driver to use 1000 Mbps full duplex
  
• Try my cable and router with another PC. It works
  
• Try to boot from a live USB running Ubuntu 21.10. It also didn't reach full speed
  

The funny thing is that if a plug a USB Ethernet adapter (TP-link UE330), it reaches gigabit speeds with that cable and router; and then if I reconnect the cable to the Ethernet port on my PC, IT WORKS at gigabit speeds for as long as I have the PC turned on. When I restart, it goes back to 100 Mbps.

As of course, I prefer not to have to depend on a USB dongle to reach full speed on my network, what can I do?

 

Ethernet Link Speed at 10 Mbps

• The light coming from the Ethernet port is blinking yellow
  
• On my mother board box it says its a '10/100/1000 Mbps Gaming LAN'
  
• The driver I am using is Realtek PCIe GbE Family Controller (Driver version: 10.54.1111.2021). This is what automatically installed when I uninstalled the driver and restarted
