I have a Lenovo with Qualcomm Atheros QCA61x4 Wireless Network Adapter. I setup it as dual boot Ubuntu 15.10 and Win10. The wireless card works fine on Win10, but is not recognized in Ubuntu.
Here is some output from my Linux terminal:

$ lspci | grep Net
01:00.0 Network controller: Qualcomm Atheros Device 0041 (rev 20)

$ sudo apt-get install linux-headers-$(uname -r)
...
linux-headers-4.2.0-16-generic is already the newest version.

$ dmesg | grep -c ath10k
0

Please do not mark this question as duplicate of Ubuntu 14.04 Wireless not working: no network interface. Atheros [168c:003e] device because its answer

This device is supported in Ubuntu 15.10 with the latest update

was incorrect in my case.

Please advice.

  • It probably is supported in 15.10 by the driver ath10k_pci but it likely doesn't have the needed firmware. Check the message log: dmesg | grep ath10k Edit your question to add the result and I will propose a solution.
