Migrated to Leap 16.0, no network

English Network/Internet
1

I used the opensuse-migration-tool to go from Leap 15.6 to 16.0. It boots OK, but there is no network. Both wired and wireless worked in 15.6. The taskbar icon says “No available connections”.

howard@HP-oS160:~> nmcli device
DEVICE  TYPE      STATE                   CONNECTION 
lo      loopback  connected (externally)  lo         
howard@HP-oS160:~>

and Network Interfaces - Info Center shows

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host noprefixroute 
       valid_lft forever preferred_lft forever

Yast Network shows connection is controlled by NetworkManager, but nothing happens.
How to fix?
Thanks,
Howard

@crmrhm missing firmware or driver… what is the card(s)?
/sbin/lspci -nnk | grep -EA3 "Net|Eth"

3

What networking were you using on 15.6? Wicked or NetworkManager?

NetworkManager

@crmrhm is kernel-firmware-realtek installed?

7

Yes:
kernel-firmware-realtek - Kernel firmware files for Realtek wireless drivers
Version: 20250717-160000.1.2

8

@crmrhm well it contains the firmware for that card as well: 10ec:8168
/sbin/modinfo r8169

What about journalctl -b output and look for errors?

9

I could not find any errors about network cards.

10

@crmrhm and no additional repos added on the Leap 15.6 setup?

11

Fixed

Sauerland was in 15.6 but not 16.0. I remembered something about the r8169 driver being a problem. I downloaded files
r8168-ueficert-8.055.00-lp160.66.36.x86_64.rpm
r8168-kmp-default-8.055.00_k6.12.0_160000.5-lp160.66.36.x86_64.rpm
r8168-blacklist-r8169-8.055.00-lp160.66.36.x86_64.rpm
from Sauerland on another machine, installed them here, rebooted, and there is network.
Great joy.
Howard
