my wifi adapter is Intel® Dual Band Wireless-AC 3168 and wifi is not working . i searched for my adapter driver on intel site and found this :http://www.intel.in/content/www/in/en/support/network-and-i-o/wireless-networking/000005511.html
so according to intel website i need kernel 4.6 atleast to enable my wifi
what option i tried and failed
option1. tried to manually update kernel(Linux viking-HP-Pavilion-Notebook 4.4.0-36-generic #55-Ubuntu SMP Thu Aug 11 18:01:55 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux) using commands wget http://in4serv.com.br/backup/kernel-4.6.2 sudo chmod +x kernel-4.6.2 ./kernel-4.6.2
it installed the kernel but i am unable get it running ..even tried the advanced boot option .system was still running 4.4 kernel
option2 : used ukuu kernel udate utility and installed latest kernels successfully but not able to get anyone of them running .system still boots using 4.4 kernel. the advanced boot option does not shows the latest installed kernel
option3: downloaded the driver firmware files from intel website (iwlwifi-3168-ucode-22.361476.0.tgz) and tried to copy it to /lib/firmware but unable to do so..
so i am stuck with 4.4 kernel and unable to install driver so wifi is not working
any help is highly appreciated as i wasted lots of hours to get it work but of no use..
