I have an Acer Aspire 7 A715-71G-75B3. I recently installed Debian on it with wicd. When I run wicd-client, I can't see any network displayed.

I think my WiFi card isn't activated (even though rfkill says otherwise, see the command at the end). I should be able to activate it by pressing Fn+F3 but it's not working. On the other hand, the other key combination are working. (like Fn+F4 to put the PC in sleep mode)

I can't see any option to activate it from BIOS and the key combination is working on Windows (dual boot).

Is there any ways to activate it from the cmd line or something?

Here's the result of differents command I used already:

    Atheros QCA6174 is well supported. Two possibilities: 1. a conflicting module or 2. missing firmware.

    I don't know much about this so I suggest you run this Ubuntu Forums script ubuntuforums.org/showthread.php?t=370108 with an alternative internet connection (or run it offline) and add the results by editing the question.

As MichealBay said in the comments of my original question it was a missing firmware.

Indeed, after running the script he talked about here. I could see that the command dmesg returned this :

[    3.224796] ath10k_pci 0000:02:00.0: firmware: failed to load ath10k/QCA6174/hw3.0/firmware-5.bin (-2)

So I went to this github and downloaded the following ath10k archive. Then I extracted the zip file to the folder :

/lib/firmware/ath10k

Wich I had to create.

Thenn in the both folders :

/lib/firmware/ath10k/QCA6174/hw2.1/
/lib/firmware/ath10k/QCA6174/hw3.0/

I had to rename the files :

hw2.1/firmware-5.bin_SW_RM.1.1.1-00157-QCARMSWPZ-1 to firmware-5.bin
hw3.0/firmware-4.bin_WLAN.RM.2.0-00180-QCARMSWPZ-1 to firmware-4.bin

After a reboot it was working fine.

Hope this will help.
