I did the usual pacman -Syu command I do maybe once a week and restarted the notebook.
After rebooting in xfce environment I tried the usual
sudo netctl start wlp2s0-WIFIHOME
that I use to connect to my wifi. This always works. However, now I suddenly got this:
Job for netctl@wlp2s0\x2dWIFIHOME.service canceled.
I have never seen this message before. So I tried some more:
$ sudo ifconfig wlp2s0 up
SIOCSIFFLAGS: Input/output error
Never had this error message either before when manually setting a network device to 'up' (or down). Next..
$ sudo netctl status wlp2s0-WIFIHOME

Totally at a loss now since this has never happened before in the 2 years of me using arch on this notebook now. Any help appreciated!
(I'm writing this btw via a bluetooth tethering connection to my phone I managed to fashion by issuing the dbus-send command the archwiki instructed to do.)

SOLUTION:
Old: Downgrade to 5.4.15.
New: Upgrading to Kernel 5.5.11 fixes it (the versions in between 5.4.15 and 5.5.11 do not fix it)!

Did you try to manually remove the driver and then reboot?
Maybe some older firmware needs to be unloaded first.

Thanks for your reply! "remove the driver"? No I haven't tried such a thing. Is that safe? What driver is that? Why is it suddenly needed when it wasn't for 2 years, just asking, lol?
That page you linked had kinda complicated stuff in it, but I figured, it means I should just do
sudo rmmod rt2800pci
right? Is that a 'normal' or 'common' thing to do, something that people usually do to make wifi work again?
And after rebooting do I have to add this removed driver again somehow, or is removing the only thing needed?

Yes, rmmod as root would unload the driver.
You don't need to use sudo and I don't know what your WiFi driver is.
There are multiple drivers for different chipsets.
How did you install Arch?
Update: You can find your wifi driver by running
lspci -nnk | grep -A4 "Network controller"

Thanks, I did that and removed 2 drivers, because the 1st one said it depended on the other and couldn't be removed:
$ lspci -nnk | grep -A4 "Network controller"
02:00.0 Network controller [0280]: Intel Corporation Wireless 8260 [8086:24f3] (rev 3a)
Subsystem: Intel Corporation Wireless 8260 [8086:0110]
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi
$ sudo rmmod iwlwifi
rmmod: ERROR: Module iwlwifi is in use by: iwlmvm
$ sudo rmmod iwlmvm
$ sudo rmmod iwlwifi
and I rebooted. After reboot I tried to start the netctl stuff again and also tried to ifconfig up the adapter again and got exactly the same errors/problems as described in the op, so unfortunately this driver stuff seems to have no effect so far.
(Just for the record: I also tried to connect before actually rebooting, but then netctl would just hang and ifconfig would say that the interface doesn't even exist - which makes sense I guess if its driver got removed.)

That's also fine.
Please upload your journal since boot and dmesg to a pastebin and link them here:

Also: does it work w/ the lts kernel and ceterum censeo: do you have a parallel windows installation?

lts kernel? I only know that term from Ubuntu, where you have the long-time support version for download. That exists in archlinux too? So I guess no, I haven't tried that, didn't even know it exists..
No, I don't have a Windows installation.

However

You might have to downgrade linux-firmware.
Offline
Thanks! I got it working!
The hint about the firmware was helping: I tried to downgrade it, but didn't work out, same errors happened. But dmesg / journal looked slightly different. So I tried downgrading the kernel too, from latest 5.5.1 to 5.4.15 (previous version). And everything is working again!
So, solution:
Downgrade kernel from 5.5.1 to 5.4.15 (previous version): Packages linux and linux-headers.
Downgrade linux-firmware from 2020-01-22 to previous version 2019-12-20. (<-edited: Not required! It was only the kernel. And apparently some ppl say that 5.5.2 makes it even worse, see discussionfurther below.)
I wonder, though. I'm using a kabylake CPU and its integrated intel wifi.. so that means that everybody else who has a kabylake CPU will get his wifi killed after updating his system now?

Did you try to upgrade the firmware again (because in that case it's a kernel regression and not a firmware issue for pretty much sure)
Edit: and also please check whether the microcode errors are still there (and were just a red herring)

FWIW, hit the exact same problem. I can confirm that only the kernel downgrade is required. I'm running on the Linux 5.4.15 package, with the latest linux-firmware package. That configuration works, my wifi is happy.
Full dmesg of the firmware crash follows. TL;DR: it's crashing when the kernel driver sends a GEO_TX_POWER_LIMIT command. Googling, I was only able to find references to GEO SAR work that happened in the 5.3 timeframe, and 8000-series chipsets were excluded at that time by virtue of using a v36 microcode. Guessing that changed, or a logic bug was introduced in feature selection in 5.5.
Is there a regression bug already filed for this? If not, happy to do so.

Re! Confirmed! I just updated linux-firmware to max again and it still works!
I noticed kernel 5.5.2 just got released too, but didn't dare to update that one yet xD.

There's a patch but only on the kernel in the testing repo and there's at least one claim that it actually worsened the situation

This is my card:
08:00.0 Network controller [0280]: Intel Corporation Dual Band Wireless-AC 3168NGW [Stone Peak] [8086:24fb] (rev 10)
Subsystem: Intel Corporation Dual Band Wireless-AC 3168NGW [Stone Peak] [8086:2110]
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi
I had the same problem. Downgrading linux to 5.4.15 solved it.
Newest kernel 5.5.2 does not fix this problem.

I have the same card. 5.5.2.arch2-2 in testing fixes it for me.

@rohtie can you test applying https://bugzilla.kernel.org/show_bug.cgi?id=206479#c2 on top of 5.5.2.arch2-2

Just wanted to add here: The bug still persists in 5.5.8. I just tried to upgrade from 5.4.15 and had to downgrade back all the way again, as the intermediate 5.5.x steps didn't work either.

@millus if the dmesg is the same as in post #16 it is fixed by the patch from https://bugzilla.kernel.org/show_bug.cgi?id=206479#c4

I've just tested in 5.5.10 and the bug still persists
5.4.15 works
