How to make "Atheros QCA9377 ... (rev 31)" work on Debian

[rpf]

Hi,
today I installed Debian 9. Now I have troubles with my WiFi - it doesn't work.

lspci reports "Qualcomm Atheros QCA9377 ... (rev 31)":

Code: Select all

~# lspci | grep -i 9377
02:00.0 Network controller: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 31)

But the ifconfig doesn't list a WiFi-Device

Code: Select all

~# ~# ifconfig

How can I fix this failures? Thanks for any advice.

What makes this probably the most asked question here? Almost all wi-fi hardware now requires additional non-free firmware to work, in addition to the driver that's hopefully already in the kernel (brand-new hardware may require a brand-new kernel update). Debian's commitment to libre software means that the standard install ISOs don't include the firmware, though you can get versions that do include it.

After install, you can add the nonfree section alongside "main" in the entry for the primary Debian repo in your software sources list and install the firmware-atheros package. https://wiki.debian.org/SourcesList

If you need wi-fi before you can make a connection, you can manually download the Stretch deb of that package and install it it on the isolated Debian with dpkg.

My liver curses you already for just suggesting it!
