I dual booted my Laptop Acer Aspire E5-573 with Windows 10 and Ubuntu 15.10 and every since the first day I'm not able to use WiFi on any linux platform. I did everything I could have done still no use. No additional drivers available for me on Ubuntu but I'm perfectly able to use WiFi on Windows 10. WiFi chip in my laptop is Qualcomm Atheros QCA9377 Wireless Network Adapter. Please find me a solution for it.
