I have installed Ubuntu 14.04 on my system. Initially Wi-fi successfully connected to a networ. E.g.: "Mario"

After a while, I deleted "Mario" from edit connections. Then I tried to connect to the same Wi-fi again but it's not working. Why? How can I solve the problem?

  • Should appear in network manager as asual even though you edited it. Could you [edit] your post with a screenshot of your network manager (something like this: https://community.linuxmint.com/img/screenshots/network-manager-gnome.png). Please edit your post with the output of sudo 'lshw -c network' and 'ifconfig -a' and 'rfkill list' – Promille Jan 27 '17 at 12:17
  • Please [edit] your question and add output of lspci -knn | grep Net -A2 terminal command. – Pilot6 Jan 27 '17 at 12:47
  • @Pilot6 output is kernel driver in use : RTL8723BE – baldraider Jan 27 '17 at 12:53
