When I tried to use wifi in my hp laptop after sleep, it was showing netwoks but was not connecting to any of them. So I rebooted the system hoping that problem will be fixed. But it got worse. Now wifi option is gone from settings and panel. I tried to disable secure boot but it didn't help. I tried to install driver shown in this solution. But it didn't work either in 20.04. My kernel version is 5.4.0-33-generic.
Any help will be appreciated.
