rfkill hard blocked (ath9k)

My laptop got out of battery and when I tuned it on again the wifi wasn't working.
The wifi interface was DOWN and rfkill hard locked.
But that would be impossible to happen since to hard lock my wifi I needed my toggle using my FN key and that key isn't working at all (prob it's broken since I tried acpi_listen and even in winpe).
Also noticed when I plugged an usb wifi adapter on networkmanager (kde systemtray) it doesn't show my connections, but I can't connect using wpa_supplicant.
Some weird stuff also happens with my ethernet usb adapter that it doesn't show up even in "ip a" and once again nothing on networkmanager.
After passing hours trying to unplug my laptop, remove the battery, trying other kernels, checking firmware, blacklisting some modules, etc.
Found that if I remove ath9k module my wifi adapter, ethernet adapter and networkmanager issues are solved (ofc can't use wifi inboard since it's the one that use ath9k).
But I need the inboard wifi.

The initial state might be down and either there's a firmware loading error (system journal, in doubt post the entire "sudo journalctl -b", not some grep) or there's sime hibernating windows (link in my signature…)

I would like to, but without WiFi and ethernet I don't see how

Well, you're online right now…
Redirect the output into a file, copy that onto a usb key or your phone and use the system that gets you online to upload it.

We'll need *some* information on the actual situation beyond "it doesn't work".

Try blacklisting the acer-wmi kernel module.

Re: rfkill hard blocked (ath9k)

First things first…
1. You've dhcpcd and NM enabled, that's a recipe for disaster. Pick one, disable the other.
2. Your RNG is late, see https://wiki.archlinux.org/index.php/Rng-tools and sublinks - if the HW support it you can pass random.trust_cpu=on to the kernel, https://wiki.debian.org/BoottimeEntropyStarvation
3. Which device is actually hard-blocked? wlps1s0 or virbr0? Because NM very much seems to toggle wlps1s0. Post the actual output of rfkill and try to disable libvirtd to take it out of the equation.
4. There's no trace of a wired NIC - none. Are such efforts supposed to be covered by the log?

Sidenote, please don't use ubuntus pastebin service. It's terrible and requires registration for the plain text and it's ubuntu.
(Wiki recommendation is ix.io)

took some time to happen again
I have no sure if RNG is still late, but disabled dhcpcd and libvirtd.

Sep 23 06:27:25 S7C-Arch kernel: random: crng done (trusting CPU's manufacturer)

RNG is in time smile

There's a wifi/wwan mismatch

Sep 23 06:27:28 S7C-Arch NetworkManager[505]: <info>  [1600838848.1307] rfkill0: found Wi-Fi radio killswitch (at /sys/devices/pci0000:00/0000:00:1c.0/0000:01:00.0/ieee80211/phy0/rfkill0) (driver ath9k)

Sep 23 06:27:28 S7C-Arch NetworkManager[505]: <info>  [1600838848.1698] manager: Networking is enabled by state file

that has been reported and the context there was a reboot on an rfkill'd radio (airplane mode) - does that pattern fit you?

Re: rfkill hard blocked (ath9k)

Unfortunately I don't think so, I don't rly use airplane mode
This happens sometimes and it's persistent on reboot, but if I left the laptop during some time working or not and reboot some time later it normally works again. It's so weird.
