I'm dual booting windows 10 and Zorin. I had to swap from windows 11 to 10 to try fix this issue but nothing changed. Before you ask: fast boot, secure boot, etc. is turned OFF. I'm on a dell latitude 5420 laptop. My internet card is an intel AX201.
My issue: WiFi isn't an option in settings and doesn't work. lshw says its "unclaimed".
I can use my USB tethering hotspot to connect to internet.
Results of commands:
rfkill list:
sudo lshw -C network:
I know other topics have been made with this problem, but they haven't fixed my issue.
DO NOT SUGGEST
Disabling fast boot AND fast startup(done)
Disabling secure boot (done)
Shutting down for extended period of time (done)
Booting into xorg (done)

Here is my Intel Support System Utility result.
Scan Info:
Computer:
Hello and welcome,
sudo apt update
sudo apt install linux-firmware
If that doesn't work: rebuild/reinstall the driver
If firmware is present but the device is still unclaimed, the driver might need rebuilding:
sudo apt install build-essential
sudo apt install linux-headers-$(uname -r)
Then rebuild iwlwifi:
sudo modprobe -r iwlwifi
sudo modprobe iwlwifi
Check if it loaded:
lsmod | grep iwlwifi

By the way, this is my second installation with the same error
Try that
sudo apt install firmware-iwlwifi
Then reboot and check lshw again.

Package firmware-iwlwifi is not available, but is referred to by another package.
E: Package 'firmware-iwlwifi' has no installation candidate
That's a repo issue. The package should exist on Zorin 18.1. Let's fix your sources:
sudo add-apt-repository universe
sudo add-apt-repository multiverse
sudo apt update
Then try again:
sudo apt install firmware-iwlwifi

Hi and welcome.
I would follow @Nourpon 's advice.
Zorin 18 is a fork of Ubuntu 24.04, so using this in my search criteria using Brave search via Mojeek gives:
" The Intel AX201 often appears as an unclaimed network controller in Ubuntu 24.04 due to missing firmware , ACPI BIOS errors , or incompatible chipset integration (specifically with CNVio devices).
To resolve this, try the following steps:
Install/Reinstall Firmware : The most common fix is ensuring the correct firmware is present. Run sudo apt install --reinstall linux-firmware and reboot. If issues persist, manually download the iwlwifi firmware from the official Linux firmware repository and place it in /lib/firmware/ .
Disable Intel AMT in BIOS : Many users report that disabling Intel AMT (Active Management Technology) in the BIOS settings allows the AX201 to be detected and function correctly on various Linux distributions.
Check for CNVio Compatibility : The AX201 uses Intel's CNVio technology, which requires specific chipset support. If you are using a system like the Intel NUC5PPYH , the chipset does not support CNVio devices, and the card will never be detected; you must replace it with a standard PCIe card like the AX200 or AX210 .
Address ACPI Errors : If dmesg shows ACPI BIOS errors (e.g., AE_NOT_FOUND ), this may prevent the driver from loading. Updating the BIOS or adding acpi_osi=! to kernel parameters may help.
Verify Kernel Version : Ensure you are running a kernel version that supports the AX201 (typically 6.0 or newer). If using a very new kernel (like 6.14 ), check if linux-modules-extra is installed, as missing modules can cause the device to be unclaimed.

This doesn't work. I've tried all these. I don't want AI generated results.
did you disable repos in Softwares & Updates ?

Everything in software and updates is enabled
Softwares & Updates are set to main server ?

It was set to Australian server, but no change even after swapping to main
Run these two commands and paste the output:
sudo dmesg | grep -i "iwl\|firmware" | tail -30
and
ls -la /lib/firmware/iwlwifi/ | head -20

"[ 2.832803] iwlwifi 0000:00:14.3: value [iter 11]: 0x00000000
and
"ls: cannot access '/lib/firmware/iwlwifi/': No such file or directory"
Run these commands:
sudo mkdir -p /lib/firmware/iwlwifi
Now download the AX201 firmware files (the AX201 uses the 6000 series Intel WiFi firmware):
cd /tmp
wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/iwlwifi-6000-4.ucode
wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/iwlwifi-6000u-2.ucode
wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/iwlwifi-6050-2.ucode
sudo cp iwlwifi-* /lib/firmware/iwlwifi/
Verify they copied:
ls -la /lib/firmware/iwlwifi/
Then reboot:
sudo reboot
After reboot, check if the device is claimed:
lshw -C network
