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:

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!

Hi I ported over a native build of Unbuntu server provisionally hosted in Windows Hyper-v to my NUC, booted fine no integrated network device picked up. Would like to thank the folks in the thread for breaking out of my loop, the command from user1608347 sudo ifconfig eth0 up, and prior to that using the following command to determine the device was detected, but disabled via lshw -class network sorted me out, no need to reinstall the BIOS firmware, many thanks.
