In my Acer laptop, wireless driver atheros is not supporting with Ubuntu. It is working with windows 10.

What Windows does or doesn't do is of near zero value. It is a completely different OS with completely different support.

What is the output of:

sudo lshw -C network; lsb_release -a; uname -a; sudo rfkill list

Thanks

Your wireless card is not supported yet in Linux. It will likely be supported by ath10k sometime in the future

lashw -C network

I have installed the kernal version 4.2.5 in my system but still its not working. Ubuntu version is 14.04.

During installation it was showing an error with ath10k. Should I upgrade to Ubuntu 15.10 or not?

Use your 3.19 kernel and try my commands from
http://ubuntuforums.org/showthread.php?t=2300861&p=13381444#post13381444

I patched backports with a patch just released yesterday and it might work

Post the result of

lspci -nnk | grep -iA2 net

before running the commands
