I am experiencing problems with wifi on newly installed ubuntu 16.04.

For this reason I have followed steps described in this answer.
However now the wifi connections completely disappeared from networks.
How can I fix this?

I have tried to do

sudo ifconfig eno1 up
sudo service network-manager restart

But nothing changes

Outputs from commands:

ifconfig

  • Please post results for rfkill list Thanks – Jeremy31 Aug 07 '17 at 16:28
  • i have noticed that my network adapter was disabled and I don't know why the configuration had a title of 'rename3'. Running sudo ifconfig rename3 up sudo service network-manager restart have solved the problem – rahimli Aug 08 '17 at 07:34
