As you can see in your dmesg, ath10k is looking for a firmware for your device (QCA9377/hw1.0/):

But, here are the good news. There is already a firmware for your device in the ath10k-firmware.git (https://github.com/kvalo/ath10k-firmware). You may test this firmware by copying the related subfolder (QCA9377/hw1.0/) to /lib/firmware/ath10k with root permission. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1523565 Title: Qualcomm atheros network controller [168c:0042] (rev 30) does not work Status in linux package in Ubuntu: Confirmed Bug description: I installed the latest ath10k kernels, which changed the status of the hardware from unclaimed to claimed, but it still does not seem to be recognized as a wireless device ProblemType: Bug DistroRelease: Ubuntu 15.10 Package: linux-image-4.2.0-19-generic 4.2.0-19.23 ProcVersionSignature: Ubuntu 4.2.0-19.23-generic 4.2.6 Uname: Linux 4.2.0-19-generic x86_64 ApportVersion: 2.19.1-0ubuntu3 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: (removed for privacy) 1358 F.... pulseaudio /dev/snd/controlC0: (removed for privacy) 1358 F.... pulseaudio CurrentDesktop: Unity Date: Mon Dec 7 21:22:43 2015 EcryptfsInUse: Yes HibernationDevice: RESUME=UUID=ec603e54-8e2b-40c2-9bd4-559d5e329d2c InstallationDate: Installed on 2015-12-07 (0 days ago) InstallationMedia: Ubuntu 15.10 "Wily Werewolf" - Release amd64 (20151021) IwConfig: enp2s0 no wireless extensions. lo no wireless extensions.
