Bug Description

I dual booted my Windows computer with Ubuntu 14.04 because my professor needed me to be compatible with the lab. On my Windows partition, the wifi works. On Linux, it does not work at all. I have tried to sudo-apt get install many backports, and none of them worked.

It is odd that lspci shows you have a Qualcomm Atheros QCA9377 with driver ath10k_pci, but dmesg shows nothing about ath10k as QCA9377 never exists.

Can you run lspci -v to confirm QCA9377 and run "sudo modprobe -r ath10k_pci ; sudo modprobe ath10k_pci" to unload and reload wifi driver. Also run dmesg to check why driver fails to loaded.

You can also update linux-firmware (from http://security.ubuntu.com/ubuntu/pool/main/l/linux-firmware/) and / or update system BIOS (do it with cautions).
