    Default XPS15: Ethernet through Thunderbolt port not working

    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:

    Code:
    :~> 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:

    Code:
    # hwinfo --disk --only /dev/sde

    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?
    Code:
    /usr/sbin/hwinfo --netcard
    Also, when a LAN ethernet cable is connected, does the link state reflect that?
    Code:
    ip link
    Report back with the output of those two commands

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

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

    Code:
    $ nmcli device
    
    DISPOSITIVO  TIPO      ESTADO         CONEXIÓN 
    wlan0        wifi      conectado      eduroam  
    eth0         ethernet  no disponible  --       
    lo           loopback  sin gestión    --
    Note that the second line was not there before plugging in the adapter (it's Spanish, sorry).

    Code:
    $ /usr/sbin/hwinfo --netcard

    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.

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

    Try
    Code:
    ip link set dev eth0 up
    then check link state again. Any different?

    Not really

    Code:
    # ip link set dev eth0 up
    
    # ip link
    1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000

    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.

    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:


    Code:
    # ifconfig 
    eth0      Link encap:Ethernet  HWaddr 00:E1:4C:68:7B:FC  
              UP BROADCAST MULTICAST  MTU:1500  Metric:1
              RX packets:0 errors:0 dropped:0 overruns:0 frame:0
              TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
              collisions:0 txqueuelen:1000 
              RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
    Code:
    # ip link
    1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
        link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    2: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
        link/ether 9c:b6:d0:d9:22:a7 brd ff:ff:ff:ff:ff:ff
    3: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 1000
        link/ether 00:e1:4c:68:7b:fc brd ff:ff:ff:ff:ff:ff
    Perhaps related to this issue, the last message in dmesg when the usb is plugged is a suspicious 'stop' message:

    Code:
    [ 4041.919727] r8152 4-1.1:1.0 eth0: v1.09.9
    [ 4067.453924] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
    [ 4067.463481] r8152 4-1.1:1.0 eth0: Stop submitting intr, status -71
