Your wifi interface clearly appeared before and iw confirms that.. Which means that it is correctly installed and recognized. I don't understand why you say it does not appear in system settings... Where are you looking? The txpower at 0dbm suggest that it is not "up". Please trysudo ip l s wlp6s0 upand shows us yoursudo iw devstdout after that. what is strnage is this "dell wireless" interface... wtf is that? to be sure that it is not bllocking somehow your qualcom. you have on this interface a soft block (dosudo rfkill unblock wifi) and a hard block (check efi-bios and button)

Your wifi interface clearly appeared before and iw confirms that.. Which means that it is correctly installed and recognized. I don't understand why you say it does not appear in system settings... Where are you looking? The txpower at 0dbm suggest that it is not "up". Please try
sudo ip l s wlp6s0 up and shows us your sudo iw dev stdout after that. what is strnage is this "dell wireless" interface... wtf is that? to be sure that it is not bllocking somehow your qualcom. you have on this interface a soft block (do sudo rfkill unblock wifi) and a hard block (check efi-bios and button)– kcdtv

Guys i tried contionusly for a month then able to find solution of problem "No WiFi adapter found " , the problem is same in all versions of ubuntu because i tried Ubuntu 16.04 and then Ubuntu 14.04 , but i finnally able to find the solution.I almost tried each and every solution available.
In my case the output of rfkill list
0: dell-rbtn: Wireless LAN
Soft blocked: yes
Hard blocked: yes
so to solve the problem i need to blacklist dell-rbtn (this is hardware issue)
to balcklist dell-rbtn, i did
echo "blacklist dell-rbtn" | sudo tee /etc/modprobe.d/dell-rbtn.conf
and after this reboot the laptop and now i m able to use WIFI.
I hope this will help someone because i also tried for months to solve this problem. Thanks
One last thing my laptop configration Dell Inspiron 3542 and Network controller [0280]: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter
