Realtek Drivers for LE 12.2

hnxx · August 4, 2025 at 5:28 PM

Hey, that are great news.. Will it come with realtek-r8125 drivers? There are some problems with intel/asus nucs.. they use the r8169 driver by default, which is automatically loaded by the kernel. However, this driver is not correctly compatible with the RTL8125 and i always have to blacklist the r8169 driver

No.

What do you mean? RTL8125 is supported by r8169 since forever.

it seems that some linux kernels use the rtl8169 instead of rtl8125.. Maybe itś not detecting correctly

From Linux 6.16 kernel Kconfig options ^ .. the RTL8125 chip is supported by the r8169 driver so 'all' kernels (not some) are using that driver with that chip.

You will need to describe in more detail (and provide system logs) detailing the actual problem. NB: blacklisting r8169 will disable part of the ethernet stack, but not all of it. You will still see the Realtek PHY being probed and detected.
