@Pilot6: could you convert last comment above this on to an answer? — Fabby, Aug 16 '15 at 17:23
You could try to install the latest firmware(updated just 3 days ago) from here: https://wireless.wiki.kernel.org/en/users/Drivers/ath10k/firmware — Yalok Iy, Aug 16 '15 at 17:24
@Fabby I gave this answer for this adapter once or twice, but I can't find duplicates. — Pilot6, Aug 16 '15 at 18:13
@Anurag ath10k does not support it yet. But I am sure it will soon. — Pilot6, Aug 16 '15 at 18:15

Follow these steps to get your WIFI. Prior to this update your kernel by installing from this page

http://kernel.ubuntu.com/~kernel-ppa/mainline/

I installed 4.0.0 since latest 4.2 crashes my bluetooth and then follow the steps from here :

Are you sure.Mine is the same laptop! – 5ud0 Sep 04 '15 at 17:08
Did u install the kernel and followed the steps exactly?
and also added the line to modprobe?
– 5ud0 Sep 04 '15 at 17:08
Yaa i tried with both the kernel's 4.2 and 4.0 with both its not working .. – Anurag Sep 07 '15 at 13:27
Sorry dude,Me and my friends got the same laptop Lenovo Z51-70.
One difference from yours is we installed Ubuntu 14.04 or elementary freya(my recommendation ;) ).May be you might have luck with that
