[arnenaessens]

Hello,

Today i installed debian 9 on my laptop next to my windows 10.
Everything seems to be working except my wifi.
Ethernet works.

lspci shows this

I have already installed firmware-atheros

Any ideas?

Does your present kernel driver support that PCI ID number? The output of (as root or with sudo)

Code: Select all

modinfo ath10k_pci

support would be shown by this line

Code: Select all

alias:          pci:v0000168Cd0000003Esv*sd*bc*sc*i*

Could you also be more specific about what's not working? Can you disconnect the wired connection and scan for available networks? What desktop are you using? The default is GNOME 3, and you should be able to try and scan with the panel widget.

One of the great things about Debian is the documentation and there are two specific web pages that deal with Debian Wifi.

Debian Wifi: howto to correctly ID your device

Wifi setup: Howto setup Network Manager in Gnome/KDE, WiCD, connman, Command Line, and special setups (wpa-enterprise) with wpa_supplicant.

Awareness of the documentation is low among new users, I feel it would allow new users to make informed choices.

Hi,
Can you tell me the specific steps you took to resolve the issue? I have a very similar situation. I just installed Debian 9 stretch on a Sony laptop Z series (that originally had windows 7 pro), and the wifi doesn't work. I can't even see any setting for wifi control (in the cinnamon desktop environment). When I did an lspci command, I got the following as a network controller, which I assume is the same as the wifi controller.

Code: Select all

network controller: Intel Corporation Centrino Advanced-N 6200 (rev 35)

This controller is different than your Qualcomm Atheros controller, so I may have to modify your specific solution.
Here's what I did so far:

I added the following to my sources.list:

Code: Select all

deb http://security.debian.org stretch/updates main contrib non-free
deb http://httpredir.debian.org/debian stretch main contrib non-free
deb http://httpredir.debian.org/debian stretch-updates main contrib non-free
deb-src http://httpredir.debian.org/debian stretch main contrib non-free
deb-src http://httpredir.debian.org/debian stretch-updates main contrib non-free

and did:

Code: Select all

# apt-get update
# apt-get install firmware-ipw2x00 wireless-tools

Any help would be appreciated.
Thanks!
