I just got a new computer (HP Envy) and installed elementary OS. As you may know, a lot of HP laptops come with Intel wireless drivers and they do not work on Linux right after the installation. And mine is not an exception. I do not see wireless option in the network setting. Right now, I am connected to internet by USB tethering using my phone.
My wireless driver is Intel Wireless AC9560. I have tried many different methods online but failed. Could anyone help me get my wifi working?
p.s. I also could not install elementary tweaks on my computer. While adding the PPA, it always returned
