Always unless I hit a snag (not that I have). Linux-5.5.2.arch1-1 is my fallback. I might also install linux-lts.

No itās not fixed in the kernel 5.5.2 update. If itās of any interest to anyone running vanilla arch on a machine with the AC-3168 wifi card, my solution was this:
I installed Linux-lts using sudo pacman -S linux-lts. Then I created an extra arch.conf file calling it arch-lts.conf and amended the two linux lines as below:
linux vmlinuz-linux-lts
initrd /initramfs-linux-lts.img
This file has to go into /boot/loader/entries/
On reboot, you get the choice of arch linux or arch-lts linux at the boot loader screen.
With the linux-lts kernel, the wifi ac-3168 card is recognised.
I donāt know how this is done with Grub, but I expect it is a similar method. When the linux kernel or linux firmware is patched to correct the problem, Iāll go back to the latest arch linux.
I should add that my Intel NUC5PYH running Endeavouros does not have the wifi problem - different wifi card.
Itās fun isnāt it?
In grub, after installing linux-lts, the following command is needed:
sudo grub-mkconfig -o /boot/grub/grub.cfg
and after reboot you have a choice.
Even tje rc,s are developiing for three months is normal in first release has some iccups probablt at 3th minor releaze it fixes zelf i use linux-zen and linux-lts lts is for fallback, also in my systemdboot i made a entry that bootsndirect in tty lol
With the 5.5.2 update there was also a new version of the NVIDIA 440 driver. Soā¦ not sure what helped, but less clipping when moving windows and scrolling browser windows now.

Sorry about the late reply. Was too busy. There was an immediate update for that Kernel and the patch has fixed the screen tearing issue. Iām using 4.19 LTS kernel anyway.
BTW; My āgrep VGAā is Intel UHD 630. No dedicated graphics card.
Thanks @Resiliencia
Now it seems that wifi is working again with update of linux 5.5.2.arch2-2. It probably worked with 5.5.2.arch2-1 already, but then I didnāt pay attention to it.
Note that Iām testing this with the [testing] repo, so new kernel should be released soon to the stable line.
And the sound in kaffeine seems to work too.
This āordealā is a great demonstration about the benefits of having both kernels installed: linux and linux-lts.
The new kernel is working fine for me, even my antique Dell D430 & D630 work well.
Iām still having the screen tearing issues on 5.5.2-arch1-1. They are not horrible, but pretty constant. I have an ATI graphics card (AMD legacy). xf86-video-vesa 2.4.0-2, xf86-video-fbdev 0.5.0-1, xf86-video-ati 1:19.1.0-1 and xf86-video-amdgpu 19.1.0-1 drivers installed. Running XFCE with i3 as DE.
@Tasia91
Have you tried setting the v-blank settings to off or xpresent on Xfce? Try this and see if it helps.
xfconf-query -c xfwm4 -p /general/vblank_mode -s off
@ricklinux, unfortunately it didnāt help. But your message made me think that indeed the problem may be in my current setup. Iāve switched to lts kernel (4.19) and the issue is still present, although it seems to be worse on 5.5.2. Can it be caused by the fact that I have 2 wms? (xfce and i3) installed?
edit: seems like Iāve fixed it completely. It was probably an issue with i3wm and possibly xfce conflicts. I uninstalled xfce4 and xfce4-goodiescompletely, reinstalled only some of its apps I absolutely need. Rebooted and installed picom compositor. After running it with a simple --vsync thereās no more tearing. So far I tested it only with lts kernel, but Iām almost sure it should be alright with 5.5.2 as well.
I donāt think itās because of the 2 wms. Itās seems to be Xfceās compositor. Seems to be an issue on the AMD cards. The v-blank setting works for me on older ATI/AMD cards. Iāve never tried picom. Do you just install it with xfce or do you need to do some other things? Uninstall or change settings? Glad itās better.

@ricklinux, I was using i3wm primarily, but it makes sense that itās xfce compositor that was causing problems, because I was having screen tearing issues while running xfcewm as well. I just uninstalled xfce completely and installed picom instead, since I wasnāt really using xfce much anyway. I think itās possible to run picom with xfce too, but Iām not sure, Iām pretty much a linux newbie. As to the settings Iām just running it with one option ( picom --vsync ), but it can read normally from a config file too.

Is this Compton then? Or one of the picom-git versions?
I thought picom was the new Compton?
