Hi,
after updates my HP Z400 Workstation lost the LAN card … W-LAN dongle is still working.

See what network card you have, from the terminal, with:

lspci | grep Ethernet

If your network card is Broadcom, try disconnecting the cable, and execute the following (from the terminal and as root):

# modprobe -r tg3
# modprobe broadcom
# modprobe tg3

Plug your network cable back in and check whether the module succeeded with:

# dmesg | grep tg3

If this procedure solved the issue you can make it permanent by adding broadcom and tg3 (in this order) to the MODULES array:

sudo nano /etc/mkinitcpio.conf

MODULES=(.. broadcom tg3 ..)

Regenerate the initramfs:

# mkinitcpio -P

If your network card still doesn’t work, try starting from the RebornOS installer, and test if you have internet access.

If you have a LAN connection, that may mean that the new kernel installed on your system does not have the correct driver for your lan. I suggest you install (if you don’t already have it) the LTS kernel:

sudo pacman -S 	linux-lts linux-lts-headers
sudo grub-mkconfig -o /boot/grub/grub.cfg

If you already have the LTS kernel installed, do the following from the terminal:

sudo grub-mkconfig -o /boot/grub/grub.cfg

Reboot and test if you have a LAN connection. (Select Advanced options for RebornOS, and select LTS Kernel).

Note that if you have installed the NVIDIA driver, you will need to make the necessary changes to make it work with the LTS kernel (using nvidia-dkms).

first thanks a lot for the fast answer,

after the 3 modprobe´s the network comes up …
i did add in mkinitcpio.conf broadcom and tg3
looks:
MODULES=“crc32 libcrc32c crc32c_generic crc32c-intel crc32-pclmul broadcom tg3”
did regenerate mkinitcpio - but after reboot is enp1s0 still not present.

If you try the LTS kernel, what happens?

Have you tried the ISO of the installer, to see if you have a network there?

have try LTS kernel bevore have ask for help
there was also no broadcom … but is it not supported if modprobe works?

but the ISO - u speak about the last one ? not tested up to now …

yeh I need to test the last installer

Greetings.

Before making the changes to the mkinitcpio.conf file, it never told me if after the tests indicated before this, it had a network connection or not.

The best thing is that you try to test with the LIVE installer if you have a connection (with the latest one), and if you don’t, try to try another installer. It may also be the case that the network cable is not in good condition. I do not know. But we need to confirm that the network connection works.

Greetings, and I hope you have a nice day!

Hi,
Win10, EndeavourOS, Manjaro, Elementary, Studio, Kali, Parrot, Geruda have no problem with

also understand:
