I upgraded to Kubuntu and my WiFi is not working. I already tried the most obvious things, I also have some info.

This is an issue with newer HP Notebooks running newer Intel wireless cards. Blacklist "acer-wmi" and "acer-wireless" in /etc/modprobe.d/blacklist.conf.
Add the lines
blacklist acer-wmi And reboot.
Ubuntu tries to load the acer-wmi and wireless module which erroneously blocks the wireless.
Edit: if the wireless card/firmware continues to fail, please run the command:
dmesg | grep iwl And edit your question with the output.
