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.

  • sudo lshw -class network will show which network interfaces were found. find /lib -name rtl8723\* will show which relevant drivers are available. sudo modprobe rtl8723be and dmesg | egrep -i 'rtl|real|net|eth|wifi|error|fail' may provide information. If you have a wired connection you could add the output of those commands to the original question.
