Finally, after reinstalling Windows from scratch and installing the drivers in a specific order, Windows detected and correctly configured the two LAN network adapters, as well as the WLAN adapter.
I had been working fine for a while, but suddenly I lost my internet connection. Apparently, it indicated that the two LAN network adapters were disabled. I tried to enable them, and although there were no errors in the process, they did not finish enabling.
With the two LAN adapters disabled, I restarted Windows, and when it started up again, the LAN network adapters no longer even appeared in Device Manager.
I had updated the BIOS with the latest version available in the download area.
