[solved for now] Difficulty with Intel Wireless 9462AC Card

Hello.
I have recently begun using Arch after a few months of absence (August was my last login), so I decided to update my Dell G3 15 laptop's Arch install by executing "sudo packman -Syyu".
Now apparently my wireless card "Intel Wireless 9462AC" cannot be set to up. Well, specifically wlo1 cannot be set to up, but I remember that wlo1 is the correct device.

I'm sorry that I can't post more useful information, as I am a bit of a novice when it comes to Linux in general (as in I have not used it for long, but I would like to think that I have a decent amount of knowledge since I set it up and got a window manager [i3 gaps] and Steam to work, and customised the status bar).

Just ran "dmesg | grep 'iwlwifi' | less" and scrolled down, it correctly identified the card as AC 9462. The line says "Detected Intel (R) Dual Band Wireless AC 9462, REV=0x318"

It also, rather worryingly says a few lines below, "wlo1: renamed from wlan0".

Thanks. How do I apply Mehmet's patch to my kernel? I am struggling to understand the PKGBUILD system.
Sorry to be troublesome.

Patching_packages#Applying_patches
As the kernel package automatically applies any file with a .patch extension you just need to add the patch to the source and checksum arrays.

git clone git://git.archlinux.org/svntogit/packages.git --single-branch --branch "packages/linux"
cd packages/trunk
curl -o 0001-Revert-iwlwifi-mvm-fix-scan-config-command-size.patch https://bugs.archlinux.org/task/64703?getfile=18121

Modifiy the PKGBUILD here.  git diff of changes:

git diff
diff --git a/trunk/PKGBUILD b/trunk/PKGBUILD

 export KBUILD_BUILD_HOST=archlinux
 export KBUILD_BUILD_USER=$pkgbase

Then build the package then install the package makepkg generated.

I can't execute the git clone or curl because my computer cannot access the Internet due to a lack of WiFi. I managed to download the patch by going to my Dad's Windows desktop and downloading it to a USB flash drive.

I would suggest you downgrade the kernel package to restore WiFi connectivity.

I downgraded my kernel and headers using the pacman cache, everything works now, thanks. I guess I'll have to wait for a version without this problem.
