Lenovo Legion Y540 wifi problem

Question

I recently installed dual booted Ubuntu 16.04 with Windows 10 and now I'm facing problems with Wi-Fi. It says Wi-Fi is not enabled.

When I modify the network configuration it says "not managed." Below are the details.

iwconfig:

enp7s0    no wireless extensions.

lo        no wireless extensions.

wlp0s20f3  IEEE 802.11  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=0 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:on

lspci -knn | grep Net -A3; rfkill list:

Did output of rfkill list change? Please add output of grep ideapad /etc/modprobe.d/* to your question. — Pilot6, Aug 17 '19 at 10:00
