How to enable Ethernet Interface (Ubuntu 22.04)

Question

Laptop: HP Spectre X360 15-bl001na

Ubuntu 22.04 does not see any wifi network, then I checked with the command below and I see a "DISABLED".

How can I enable that interface?

$ sudo lshw -class network
  *-network DISABLED

And the results of sudo ifconfig eth0 up and ifconfig -a:

$ sudo ifconfig eth0 up
eth0: ERROR while getting interface flags: No such device
$ ifconfig -a

and the result for frkill is:

$ rfkill list all
1: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
2: hci0: Bluetooth
    Soft blocked: yes
    Hard blocked: no

and this is the content of /etc/network/interfaces is:

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

I can also add that, in the Ubuntu config panel, WiFi is of course enabled but the "Visible networks" is spinning forever screenshot

Adding also info about iwlwifi module:

$ sudo dmesg | grep iwl

Have you tried $ sudo ifconfig eth0 up? "eth0" is the name of your ethernet connection your want to activate, and may be something different on your system. You can also use the same command to activate wifi. If you run $ ifconfig -a you get a list of all interfaces and their status. — user1608347, Jun 29 '22 at 21:26
The problem is elsewhere, I think. I can't offer you any help on that. — user1608347, Jun 29 '22 at 22:07
@Lorenzo Best to place any requested command line output appended to your question rather than placed as a new answer. I have sorted it out... — andrew.46, Jun 30 '22 at 01:15
Please edit your question to show the result of the terminal command: rfkill list all Welcome to Ask Ubuntu. — chili555, Jun 30 '22 at 01:45
Hi @chili555 many thanks for your help and suggestion about how to manage my request. I'll do, from now on, as you recommended. I'm adding the result for rfkill command — Lorenzo, Jun 30 '22 at 06:53
could you please also recommend a better title for my question? I find my title quite generic, but don't know how to technically improve it. — Lorenzo, Jun 30 '22 at 07:04
The name of your disabled device isn't eth0 it's wlp59s0. — mchid, Sep 25 '22 at 01:53
Does this answer your question? WiFi not working after upgrading to 22.04 — Artur Meinild, Oct 23 '23 at 11:10

Same issue. Figured out that I had moved around some hardware, specifically an LSI disk controller. This seemingly unrelated benign act caused my network card address to change!

To resolve just edit the auto generated netplan file

sudo  /etc/netplan/00-installer-config.yaml

cat  /etc/netplan/00-installer-config.yaml
This is the network config written by 'subiquity'
network:
  ethernets:
    enp6s0:
      dhcp4: true
  version: 2

any number of tools including ifconfig, ip a, etc. will show you what the correct interface id is. In my example the interface ID had changed from enp5s0 to enp6s0.

Hope this helps!

This isn't related in the very slightest to the original question. – chili555 Jun 28 '23 at 12:43
it is related, BECAUSE "same issue" .. the scenario as described caused the same error message and google led me to this page. – Brian Horakh Jul 08 '23 at 01:55

This is absolutely related. If the ethernet port was working, some hardware additions change the address of the port, effectively disabling it. I had exactly the same problem from adding an SSD drive. – Suncat2000 Aug 22 '23 at 03:06
