ROG STRIX B450-F GAMING II Lan port not working

[Skurk52]

So I've been modifying the BIOS to setup the windows boot before the fedora option, and I saw that my RAM speed was configured to be 2400 when it should be 3200, so i changed that too. but when Windows loaded, I had no ethernet connection, and the port lights were off. Im not even sure if the port can be disabled by BIOS, or its broken.

Hello, @Skurk52 

If you are concerned about the impact of BIOS settings, we recommend referring to "How to Clear CMOS?" and following the steps to restore the BIOS settings to default.
Additionally, may I ask for your current BIOS version, Windows version, and the network-related drivers you have installed?

Please also refer to [Motherboard] How to fix the cable network problems of Motherboard – Troubleshooting if needed.

Thank you.

Hello @Jiaszzz_ROG, thanks for the help.
I've already cleared the CMOS, and I updated the BIOS to the last patch after the problem, but its still there.
I use Windows 11 22H2 and Fedora 38

Hello, @Skurk52 Sorry for any delay in response.

Since the relevant drivers on the official website are for Windows, could you please remove the Fedora Linux system disk first to avoid any confusion and then further verify the issue?
Could you also help confirm whether your current memory is listed in the QVL of the ROG STRIX B450-F GAMING II and installed in the recommended slots as per the user manual?
At the same time, according to the official website, the latest BIOS version released is 5102 on June 12, 2023.
We recommend that you update and check the issue again under the default BIOS settings.

Thank you.
