    Wired Network

    My wireless card is working but I cannot get my wired connection working. Here is a partial output of lshw -C network:
    *-network UNCLAIMED
    description: Ethernet Controller
    product: Qualcomm Atheros
    vendor: Qualcomm Atheros
    physical id: 0
    bus info: pci@0000:03:00.0
    version 10
    width: 64 bits
    clock 33MHz
    capabilities: pm pciexpress msi msix bus_master cap_list
    configuration : latency=0
    resources: memory:92c00000-92c3ffff ioport:2000(Size=128)

    How do I activate and set it to DHCP? It's currently plugged into a network.

    Re: Wired Network

    Unclaimed means that it lacks a working driver. Let's see why. Please run and post:

    Code:
    lspci -nnk | grep 0200 -A3
    dmesg | grep ath
    Thanks.

    Thanks chili555; here's the output:

    The usual driver for this device is alx. Let's load it and see if there are any interesting messages, errors, etc.

    Code:
    sudo modprobe alx && dmesg | grep alx

    That's weird.

    I wonder why they always give me the hard problems to solve. Can't I get the occaisional softball, guys??

    Let's dig deeper. We'll try to see what's going on on the PCI bus:

    Code:
    dmesg | grep 03:00
    modinfo alx | grep E0B1
    That's E-zero-B-one; not a capital O.

    That means that the version of the driver alx in your system doesn't cover your exact device. Let's see:
    Code:
    modinfo alx | grep file
    lsb_release -d

    Support for 14.04.x ended about a year ago. Move to 16.04 or better, 18.04.
    https://wiki.ubuntu.com/Releases Of course, you could pay Canonical for ESM support, but most people find the cost isn't worth it due to all the other hassles they will see running a 6 yr old release.

    Chilli - you get the hard ones due to your amazing ability to get to the answer so fast.

    I had an alx NIC. It was a USB3-to-GigE adapter with 4 USB3 ports. Perfect for a laptop that didn't have any RJ-45 ports. After about 6 yrs, that device died and I got a $20 replacement which is used almost daily.
