Solved -- Help with Realtek module r8169

[garybean]

using command “lspci -v”,

under Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit

ethernet Controller (rev 15)
Subsystem: ASUSTeK Computer Inc. Device 205f
Flags: bus master, fast devsel, latency 0, IRQ 24, IOMMU group 13
I/O ports at d000 [size=256]
Memory at fc804000 (64-bit, non-prefetchable) [size=4K]
Memory at fc800000 (64-bit, non-prefetchable) [size=16K]
Capabilities:
Kernel driver in use: r8169
Kernel modules: r8169

So, wizards of Linux, where does this selection of r8169 happen?

…is " udev rules written by the administrator go in /etc/udev/rules.d/
a clue?

udev should detect your network interface controller (NIC) and automatically load the necessary kernel module at startup. Check the “Ethernet controller” entry (or similar) from the lspci -v output. It should tell you which kernel module contains the driver for your network device.

edit: removal of r8168 package solved my issue

I have the same controller in my laptop and had the same issues. Removing everything Reltek worked for me… the r8168 specifically…

I wish you luck!

[garybean]

from experience, removing the r8168 driver package results in LOSS of ethernet network connection.

my guess is that the solution is somewhere in UDEV, not the removal of any package

[mlayland]

Yes of course it will but install the r8169 in its place maybe do that first

[FLVAL]

About r8169 it depends your hardware, on mine it’s a r8168 but detected as a r8169, so the install of r8168 made it work…

Try to see first what there is in your hardware !

May have stumbled onto cause of my issue.

removed r8168 package, REBOOTED, r8169 appears under “nmcli”

ethernet network connection working!

I tried modules-load.d modprobe.d and default/grub but nothing. I had to manually modprobe r8169 every boot!

BUT Thanks to Mr G and his simple solution I have regular ethernet again!!

Thank you!!
