RHEL 9.1 , Lenovo ThinkPad X201, Intel Centrino Advanced-N 6200, not working after installation

Hello,

While installing RHEL 9.1 to Lenovo ThinkPad X201 (old laptop), wifi worked in the installer. But was no longer working after reboot when installation was complete.

Wireless device on this machine according to lspci is:
02:00.0 Network controller: Intel Corporation Centrino Advanced-N 6200 (rev 35)

sudo dnf search wireless #did not seem to find appropriate driver.

Workaround I've found. Was downloading: https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-6000-ucode-9.221.4.1.tgz using Firefox

from list here: https://www.intel.com/content/www/us/en/support/articles/000005511/wireless.html

extracting it in ~/Downloads (where Firefox by default downloads files) via GUI file manager.

Then according to README.iwlwifi-6000-ucode

sudo cp Downloads/iwlwifi-6000-ucode-9.221.4.1/iwlwifi-6000-4.ucode /lib/firmware/

so this could be done in more simple manner:

cd ~/Downloads
wget https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-6000-ucode-9.221.4.1.tgz
tar -xvzf iwlwifi-6000-ucode-9.221.4.1.tgz
sudo cp ~/Downloads/iwlwifi-6000-ucode-9.221.4.1/iwlwifi-6000-4.ucode /lib/firmware/

But I personally dont like copying and pasting binaries from third party sources into linux/bsd systems. So I wonder if there's correct way to do this in RHEL 9.1 ?
