I have a newly refurbished HP laptop:
HP HP ZBook 14u G5Intel® Core™ i7-8650U CPU @ 1.90GHz × 8AMD® Radeon pro wx 3100 / Mesa Intel® UHD Graphics 620 (KBL GT2)
I did a clean install of Ubuntu 22.04.2 LTS, with kernel version: 5.19.0-42-generic
And I discover that the computer does not see the wifi adapter. Here is the result of doing lshw – C network:

Still doesn’t work.
(New edit to my question). I found a question on Ask Ubuntu that looked like mine, involving the same intel wifi firmware:
(WiFi not working after upgrading to 22.04)
In this person's case purging the backports solved the problem. In my case, the backports are not on the computer:
sudo apt purge backport-iwlwifi-dkms Reading package lists... Done Building dependency tree... Done Reading state information... Done Package 'backport-iwlwifi-dkms' is not installed, so not removed 0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded Could this be the problem? Also what is a backport?
When I do sudo dmesg | grep iwl
I get the following message:

I would not describe myself as a superuser, but I’ve been using earlier versions of Ubuntu for years, and never encountered problems like this. Also, I know that the wifi adapter works, because the computer originally came with Windows 10 and the wifi worked without a problem (This is how I downloaded the ISO for Ubuntu). Also just to confirm from the discussion in the comments, airplane mode is off.
Can anyone provide some help here?
