No WiFi option for Ubuntu 14.04 on my lenovo yoga 510 14SK laptop. I'm new to Ubuntu and can someone help me from the scratch?

  • If you have windows installed, check if your WiFi adapter is ON in Windows. Sometimes, that also is one of the major reasons why one is not able to connect to internet in Ubuntu OS. – Manu Mathur Feb 22 '18 at 07:54
  • More often than not, the WiFi drivers are installed along with the Ubuntu OS. Check if you have a hard switch for WiFi on your laptop that's toggled Off. – lightsong Feb 22 '18 at 08:17

  • ok. in that case we will look for other options. – Manu Mathur Feb 22 '18 at 15:34
  • First, you need to find out which network card you have with this command: lspci | awk '/[Nn]et/ {print $1}' | xargs -i% lspci -ks % – atjm Feb 22 '18 at 07:55
