I am new to Ubuntu. I tried installing Ubuntu 20.04 on my Lenovo L420 laptop, WiFi is not enabled. I checked WiFi adapter it is already enabled. Even Bluetooth is working.
After I installed Ubuntu 20.04 airplane mode is automatically enabled. Then I am not able to disable airplane mode.
I used this command to disable airplane mode sudo rfkill unblock all.
I checked in additional drivers list it is showing No additional drivers available.
I am new here please help me to solve this issue.
Note: In this same laptop I installed same
Ubuntu 20.04that time WiFi was working.
