WI-FI getting disconnected/Networks not showing up on Ubuntu 16.04 solved ,Linux Teacher Sourav,Kolkata 09748184075

Install rfkill

sudo apt-get install rfkill

then run this command

rfkill unblock all

check if the wifi is working. If not do this

sudo nano /var/lib/NetworkManager/NetworkManager.state

then you will see some settings. Set everything to "true" reboot your system

give this command in terminal

rfkill list

you'll see that some are softblocked and hardblocked. All of them should be "no".

If it's not "no" then you need to somehow turn them to "no". I did this and it worked for me

sudo modprobe -r acer-wmi

cd /etc/modprobe.d

sudo nano blacklist.conf

Then add blacklist acer-wmi as a new line at the end of the file.

then save the file by pressing Ctrl+O ,close it and reboot the system. It should work
