XPS15: Ethernet through Thunderbolt port not working

English Hardware
1

Hi, I have a laptop Dell XPS 15 witout Ethernet port. Instead, I have a Thunderbolt one. I bought this adapter to get an Ethernet port when the WiFi is not available. The device includes three USB ports which work without problems, but not the Ethernet. In the network manager, I get a wired connection which appears when i plug the device, and the MAC address seems to be read properly, so the system seems to recognise that something similar to an Ethernet card has been connected. However, the connection can not be established, just as if the cable was disconnected.

Do you have an idea on how to debug this issue? I can provide more information if you tell me what is relevant for this case and indicate me how to get it.

Thank you very much in advance.

I don’t have one of those and I’m assuming it can be hot-plugged, like USB. In this case, I’d start by opening a terminal, plug the device and type dmesg to see what messages the kernel gives. With a pendrive I get something like this:


:~> dmesg

Then you could try the hwinfo as root (see man hwinfo for switches) to probe your hardware. From above I see that the pendrive is mounted as /dev/sde, so:

Then you can see a lot on info, including the driver in use. Some googling on the device code, brand or driver, etc. may yield more info and possibly a solution.

What does hwinfo show?

/usr/sbin/hwinfo --netcard

Also, when a LAN ethernet cable is connected, does the link state reflect that?

ip link

Report back with the output of those two commands

4

If using network manager (and assuming the link is up), is the device node shown?

nmcli d

Thanks for the replies. The device seems to be hardware-recognised.


$ nmcli device

Note that the second line was not there before plugging in the adapter (it’s Spanish, sorry).

To me, everything seems to be in order. Can you suggest other ways to proceed? Maybe forcing some sort of “manual setup”? I’m connected to the University Network, so I can not skip using DHCP, for instance.

6

The link state is down. Are you sure the ethernet cable is ok? Connected properly?

Try

ip link set dev eth0 up

then check link state again. Any different?

7

Not really :frowning:

Yes, it’s as if the cable was dead. But it is not, as I have tried several, and in different networks. Unfortunately I do not have Windows, so I can not test if the cable/device is the problem. But I’m pretty sure it’s not the case.

8

Try using YaST’s networksettings module, switch the networking to use wicked, then configure the device ( it’s detected, so should show up ), let it use DHCP, set it to start at boot time. You might need a reboot.

Thanks. Indeed the card is recognised and assigned as eth0, but the somewhat manual setup still doesn’t bring up the network. I have set to connect after hot plug using DHCP. But it does not work:

Perhaps related to this issue, the last message in dmesg when the usb is plugged is a suspicious ‘stop’ message:

Open a root Terminal, type:

journalctl -f

put in the Stick and post the new lines from Terminal.

I think you’re impacted by the bug described here
https://bugzilla.redhat.com/show_bug.cgi?id=1236679
whereby USB autosuspend is causing the device to sleep perhaps. In the bug report is was mentioned that tlp (power management utility) could be used with the appropriate configuration

USB_BLACKLIST="0bda:8153"

It is possible to prevent autosuspend via a suitable udev rule, but tlp simplifies power management of various system components.

The last comment in that bug report suggests that there was a bug fix in kernel 4.13.4, so if the above power management tweak is not sufficient, then perhaps trying the current stable kernel might also help here.

Sorry sauerland - missed your slightly earlier reply.

No Problem, I edited the Thread a short time before the time was gone, so no time to explain the Link as you have done.

Hi, and I’m sorry for the delay. I was not aware of the latest messages. I’ll go now through the links mentioned. Meanwhile, I have tried journalctl and this is what I get when I plug in:

Little update. I have tried a very similar device from a college (from outside, it looks just the same), and it works out of the box! The difference seems to be internal, and subtle. The one that does not work is (obtained with hwinfo) “Realtek RTL8153 Gigabit Ethernet Adapter”, whereas the working device is “Realtek RTL8152 Fast Ethernet Adapter”. The one not working seems slightly better or at least a newer model. As the kernel module is called ''r8512", I’d interpret that the kernel module is just not updated to deal with the newer model, right? So I guess I basically have to survive with the “old model” until a newer kernel fixes the problem, right?

By the way, I’m already using a fairly updated kernel to cope with other sound card issues, a version 4.14.
