Long story short, it looks like my laptop ships with different wireless cards. Here is a thread where my card is used (but on a different laptop) and here is a thread where my laptop is used (but with a different card?). I was using the workaround from the first thread (downgrade from using `firmware-6.bin` to using `firmware-4.bin`, also summarized here) for a while now only to wake up today to a non-working WiFi.

So, I hooked up to my router with an Ethernet cable and double checked that I'm using the old `firmware-4.bin` for my card. Turned out I was not: there was a new `firmware-6.bin` sitting in `/usr/lib/firmware/ath10k/QCA6174/hw3.0` since `2017-11-24`. That's weird because yesterday WiFi worked for me. Anyway, I downgraded it again and it did not help.

I'm currently running `firmware-4.bin` which does not work, I will upgrade back to `firmware-6.bin` and post `dmesg` output shortly.

Here is `dmesg` when running with `firmware-6.bin`

In both cases trying `sudo wifi-menu` or `sudo netctl start wlp5s0@some_wifi_profile` fails. For both firmwares I've also tried `sudo iw dev wlp5s0 set power_save off` which did not work.

Any suggestions?

You've not actually shown a problem. Your dmesg output does indeed show a few attempted firmware loads failing, but then it looks like one succeeds.

As for netctl not working, that introduces countless other variables (not the least of which is the obscurred "some_wifi_profile"). What is the output of `ip a`? What is the first step in connecting manually that fails or gives an error?

@Trilby thanks so much!

It turned out to be the rfkill caveat for me:

alex@k-2so ~ % rfkill list                                                                                                        :(
0: tpacpi_bluetooth_sw: Bluetooth
	Soft blocked: no
	Hard blocked: no
1: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no
2: phy0: Wireless LAN
	Soft blocked: yes
	Hard blocked: no
alex@k-2so ~ % rfkill unblock wifi

After that, my WiFi worked with the latest firmware. Will be marking as solved.
