Ethernet (NetworkManager) Troubles

orbvs · October 14, 2021, 9:48pm

Afternoon!

I have a ThinkPad T14 that has two Gigabit Ethernet interfaces: one via USB-C, one RJ45 jack.

Running Tumbleweed, using NetworkManager and KDE.

The problem is that the machine does not “see” RJ45 cables that are plugged in. Not even “dmesg --follow” shows any activity. And of course, no lights on the physical RJ45 port.

It has no problem connecting to USBC ethernet (when docked) but does not recognize ethernet cables in the RJ45 dock.

I have tried adding a connection through the KDE “Connections” panel for RJ45, but this only results in working sometimes.

Funny enough, WiFi is the most reliable connection for this machine! More than RJ45, which seems odd.

In Ubuntu Live USB, the port works fine with the same cable configuration without fail.

How do I structure NetworkManager to work with this interface? Or barring that, how do I reset NetworkManager, outside of a clean TW install (I’d rather not do that)?

Thank you for your help and time with this problem!

Some hardware details first please…

/usr/sbin/hwinfo --netcard

With an ethernet cable connected to the interface of interest, run

ip link

/usr/sbin/ethtool enp5s0

nmcli d

Post the output here for others to review and advise next steps.

Thank you for the help! Here is the hardware dump.

I separated the commands with _______ lines for ease of reading. The WLAN SSID and MAC addresses have been obscured, otherwise this is the output of each command as I see it with superuser privileges.

There doesn’t seem to be anything in my repos matching R8168…

I’ve included the repo list as well, using all the standard (and some extra) enabled repos.


~$ zypper se -si r8168

No matching items found.

Sauerland’s repo can be added using…

sudo zypper addrepo https://download.opensuse.org/repositories/home:Sauerland/openSUSE_Leap_15.3/home:Sauerland.repo

sudo zypper refresh

Install package…

sudo zypper install r8168

…then restart.

Sauerland · October 15, 2021, 11:08pm

But the question is:
why do the 2 cards not working with r8169?

Post also as root:

journalctl -b | grep -Ei 'r816|firmware|enp2s|enp5s'

@deano_ferrari
Packman has the same packages, so no need to add my Repo, because less Repos are often more… I am sometime a little bit faster in updating but packages are the same…
When using my Repo please use the Hardware branch:
https://download.opensuse.org/repositories/home:/Sauerland:/hardware/openSUSE_Leap_15.3/
There are only hardware packages and not all others.

orbvs · October 15, 2021, 11:32pm

Here is the output of the journalctl -b command:

I really appreciate your help with this!

I think the device is working, but there is some configuration issue. I can get the ethernet to light up, but only sometimes and only by adding a connection in KDE Settings > Connections > Add Wired Connection.

That works about 30% of the time to bring “up” an ethernet connection. Which leads me to think this is software based, and not firmware.

If it remains stubborn, I might resort to re-installing Tumbleweed. The machine is going to need to interface with a lot of LAN equipment soon, and a working ethernet port is a must.

Good to know. Maybe you should consider adjusting the recommended instructions accordingly…
