My son has a Sony Vaio that is running Kubuntu 20.04 lts. The wifi connection stopped working on the Vaio when we installed ubuntu 19. I had hoped that kubuntu would resolve the issue but never did. It was not a big deal until now. I researched and some said they had luck with a fresh install but no such luck here. Also there is no slider or button on this vaio that controlls the wifi. I had to use jpegs because there I could not copy and paste the results of all of the things I thought would help. I ran lspci, sudo lshw -C network, and lsmod (last 2 images).
I am not sure what else you might need. Again sorry for images and not code. I was kind of my option.
