No network after installing kernel

[CSNLinux]

Now that you're on the 4.4.x-x kernel series run the commands Jerry suggested.
 
1) sudo rfkill unblock all

2) sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/g' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Code:

sed: can't read /etc/NetworkManager/conf.d/default-wifi-powersafe-on.conf:
