How can I switch back from r8169 to r8168 on an installed system? The system runs well with WLAN and the r8169 driver, but it must also run with Ethernet (WLAN can be omitted!), which worked fine with the previous installation with r8168. A reinstallation of r8169 followed by a reboot did not improve anything.

This is a kernel module - how did you reinstall it?

Should just be a case of installing the package; if I remember correctly it will blacklist r8169.

Sorry, typo, I meant of course reinstallation of the r8168.

But exactly THAT is not what it has done at least not through sudo pacman -S r8168

And how can I do that manually?

I have now added the line blacklist r8169 in /etc/modprobe.d/blacklist.conf, but the r8169 is still in use after the reboot.

Show the output

cat /etc/modprobe.d/blacklist.conf
10 
[pany@HAL-hp ~]$ cat /etc/modprobe.d/blacklist.conf
# Disable intel mei (including mei_watchdog).
blacklist intel_pmc_bxt
blacklist iTCO_vendor_support

# Do not load the 'iTCO_wdt' watchdog module on boot.
blacklist iTCO_wdt

# Disable r8169
blacklist r8169

You are certain the it still loaded the r8169?

At least lspci -v still shows me the r8169 and my ethernet witrd doesn’t even show me to connect.

Hmm?

sudo modprobe -r r8169

sudo modprobe r8168

reboot and check again.

    vendor: Hewlett-Packard ProBook 450/455 driver: N/A modules: r8169 pcie:

it says: driver: N/A

and to use r8168 this need to be installed what will blacklist the in kernel driver: r8169 when installing the package:
/usr/lib/modprobe.d/r8168.conf
blacklist r8169

Good catch…

:scream:

16 
[pany@HAL-hp ~]$ sudo modprobe r8168
modprobe: FATAL: Module r8168 not found in directory /lib/modules/5.15.44-1-lts

but I have installed it with sudo pacman -S r8168 …

You have to install the lts version.

sudo pacman -S r8168-lts
