Please download these files (kernel version 4.7): http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7/linux- headers-4.7.0-040700_4.7.0-040700.201608021801_all.deb
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7/linux- headers-4.7.0-040700-generic_4.7.0-040700.201608021801_amd64.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7/linux- image-4.7.0-040700-generic_4.7.0-040700.201608021801_amd64.deb Then install the three files and reboot your system so it loads the 4.7 kernel. How to install these packages: 1) Execute this command in order to install Gdebi: sudo apt-get install gdebi -y 2) Right-click onto any .DEB file then go to "Properties" and define "Gdebi" as the default app to open .DEB packages. 3) Double-click the linux- image-4.7.0-040700-generic_4.7.0-040700.201608021801_amd64.deb file so Gdebi will open it. Click the "Install Package" button and provide your password. 4) Repeat the installation step (item 3, above) with files linux- headers-4.7.0-040700_4.7.0-040700.201608021801_all.deb and linux- headers-4.7.0-040700-generic_4.7.0-040700.201608021801_amd64.deb An alternative way of installing these packages is to open a shell terminal window, then cd (change directory) into the directory where those three .DEB files were downloaded into (make sure those 3 .DEB files are the ONLY .DEB files present in the folder), and then execute this installation command: sudo dpkg -i *.deb Once you install kernel 4.7, reboot your system. GRUB will select 4.7-generic by default.
